Power converter – AC 24 V to DC 12 V

A power converter – AC 24 V to DC 12 V is a device that transforms alternating current (AC) at 24 volts into direct current (DC) at 12 volts. These are also commonly referred to as AC/DC power adapters or rectifiers.

How it Works ⚙️

The conversion process from AC to DC typically involves several key stages:

  • Step-Down Transformer: The 24V AC input first goes through a transformer. This component reduces the voltage from 24V AC to a lower AC voltage, although not necessarily directly to 12V DC at this stage. It’s about getting to a more manageable voltage level for the subsequent steps.
  • Rectification: The reduced AC voltage then enters a rectifier circuit, usually made of diodes. Diodes allow current to flow in only one direction, effectively converting the alternating current (which periodically reverses direction) into a pulsating direct current (which flows in one direction but isn’t smooth).
    • Half-wave rectifiers block half of the AC waveform.
    • Full-wave rectifiers (like a bridge rectifier) use both halves of the AC waveform, resulting in a smoother, more efficient conversion.
  • Smoothing (Filtering): The pulsating DC output from the rectifier isn’t perfectly steady. It has “ripples” or fluctuations. To smooth this out, capacitors are used. These components store electrical energy during the peaks of the waveform and release it during the dips, creating a much more stable and continuous DC voltage.
  • Voltage Regulation: Finally, a voltage regulator circuit ensures that the output voltage remains consistently at the desired 12V DC, regardless of minor fluctuations in the input AC voltage or changes in the load connected to the converter. This also helps protect the connected device from voltage spikes or drops.

Applications 💡

These types of converters are essential for powering a wide variety of electronic devices, especially those designed to run on 12V DC but needing to draw power from an AC source. Common applications include:

  • CCTV cameras and surveillance systems: Many security cameras operate on 12V DC, and these converters allow them to be powered from a 24V AC power supply (which is often used in larger installations for longer cable runs due to less voltage drop).
  • Low-voltage lighting: Converting 24V AC to 12V DC for certain LED lights or other low-voltage lighting systems.
  • Industrial control systems: Some industrial equipment or sensors might use 12V DC power while the facility’s power supply is 24V AC.
  • Automotive accessories (with specific input needs): While most car systems are 12V DC, there might be niche applications where a 24V AC source needs to be converted.
  • Various electronic projects and devices that require a stable 12V DC supply from an AC input.

Power converters - AC 24 V to DC 15 V

A "Power converter - AC 24 V to DC 15 V" is a device that transforms an alternating current (AC) input of 24 volts into a direct current (DC) output of 15 volts. Here's a breakdown of what that means and how it works: AC (Alternating Current): This is the type of electricity typically supplied by wall outlets in homes and businesses. The voltage constantly changes direction, flowing back and forth. 24V AC is a common voltage for certain low-voltage control systems, industrial equipment, and sometimes HVAC systems. DC (Direct Current): This is the type of electricity that flows in only one direction. Most electronic devices, like phones, laptops, and many sensors or control circuits, require DC power. How an AC to DC Converter Works: An AC to DC converter (also known as a rectifier or power supply) typically involves several stages:
  1. Step-Down Transformer: The initial 24V AC is usually too high for direct conversion to 15V DC. A transformer "steps down" this AC voltage to a lower, more manageable AC voltage.
  2. Rectification: This is the core of the AC to DC conversion. Diodes are used to convert the alternating current into a pulsating direct current. There are different types of rectifiers (half-wave, full-wave, bridge) that achieve this with varying degrees of efficiency and ripple.
  3. Smoothing (Filtering): The pulsating DC output from the rectifier isn't perfectly smooth. Capacitors are used to "smooth out" these ripples, creating a more stable DC voltage.
  4. Regulation: To ensure a precise and constant 15V DC output, a voltage regulator is often employed. This circuit maintains the output voltage at the desired level, even if the input voltage fluctuates or the load on the power supply changes.
Applications: Converters that transform 24VAC to 15VDC are used in various applications, particularly in industrial, building automation, and low-voltage control systems where 24VAC is a readily available power source, but specific devices require 15VDC. Examples include:
  • Industrial control systems: Powering sensors, actuators, and control circuits that operate on 15VDC.
  • HVAC systems: Often 24VAC is used for thermostats and control panels, but some components within the system might require 15VDC.
  • Security systems: Powering cameras, access control devices, and other equipment.
  • Lighting systems: Especially in specialized LED lighting setups.
  • Custom electronics projects: Where a stable 15VDC is needed from an existing 24VAC infrastructure.
When choosing such a converter, you'd consider factors like:
  • Output current (Amps): How much current the connected device needs.
  • Power rating (Watts): The total power the converter can deliver.
  • Efficiency: How much energy is lost during the conversion process (higher efficiency means less heat and less wasted energy).
  • Protection features: Over-voltage, over-current, short-circuit protection for safety and device longevity.
  • Form factor: Whether it's an open-frame, enclosed, or DIN-rail mount design.

More information about the swing gate openers: WHAT ARE THE DIFFERENT TYPES OF SWING GATE MOTORS? 1- Articulated Arm for Swing Gate Operators How do automatic gates work with articulated swing gate motors? An articulated arm electric gate opener uses a two-part arm with an ‘elbow’ joint to connect the motor to the gate. This arm protrudes from the gate motor body, so there has to be room for the arm to move as the driveway gate opens and closes. This type of electric gate opener is easier to install than other types, thanks to the geometry of the arm system. They can be slightly more expensive than other gate motors, but they open and close automated gates quickly. Many homeowners like discrete gate automation systems, and articulated arm motors can be more obvious when installed. However, many have the control system built into one of the motors. These motors for automatic gates are mounted on the inside of gates so they’re not seen from the outside of closed gates. In the event of power failure or mechanical breakdown, articulated arm motors can normally be released manually from outside the gate with an optional cable release system. All articulated arm gate operators are electric gate motors that can be either 120VAC or 24VDC. All 24V and some 120V versions have obstacle detection. This means that the gates stop moving and some even reverse when they come into contact with an object during operation. Articulated arm gate automation systems can be the best choice where each electric gate opener is mounted on a large gate pier or pillar. 2- Ram And Linear Screw Automatic Swing Gate Openers Ram gate automation motors push and pull a piston mounted on the gate. Linear screw electric motors for gates use an electric motor to rotate the gate mounting along a threaded shaft. Both types of electric gate motors are slim and don’t need a lot of space to operate. However, this advantage does mean that they require careful alignment during installation. Manual release systems are only available from inside the driveway gate. A ram or linear screw type of motor for automatic gate control is attached to the gate at one end and the gate pillar or post at the other end. Ram motors can be hydraulic or driven by electric motors, but all require a separate control box. As with articulated arm motors, 120Vac, and 24Vdc, you can buy versions with obstacle detection for safer operation. Additionally, heavy-duty versions of each type of electric gate opener are available that will operate larger gates with leaves up to 7m long. These electric gate openers can be the best gate automation solution when price is important. Their simpler design and operation can make them a cost-effective solution compared to other types of electric gate motors. 3- Underground Swing Gate Operators Many Canadian homeowners choose underground gate automation motors because they are very discreet. This is because each underground gate opener is hidden under the hinge end of each swing gate. But how do automatic gates work when they’re opened and closed by hidden underground motors? During installation, a carefully positioned hole must be dug to house a foundation box for each underground gate opener. The housing for each underground electric gate motor needs sufficient drainage to prevent the motors from sitting in water, or they will fail. Underground electric gate motors don’t need a lot of space to operate and can be installed on the inside or back of gate pillars. They are usually only installed behind gate pillars when the gates must open more than 90 degrees, so that the post or pillar does not obstruct the gates. With the addition of a 180-degree gate opener, your gates can open much wider than 90 degrees. This is an optional chain drive system for driveways that bend around behind the gate pillars. If the gate only opened to 90 degrees, it could block part of the driveway. But a 180-degree gate opener system means that it can keep going past 90 degrees, so it doesn’t block the driveway. Normally, underground automation of gates is the most expensive solution, but they are almost invisible. It is possible for the most powerful underground gate opener to open and close a swing gate up to 5m long. Underground motors for automatic gates can be manually released from outside the gate. These types of gate motors can be either hydraulic or electromechanical. A separate control box is required, and 120VAC and 24VDC versions with obstacle detection are available. Underground gate opener installation is not simple, and it should always be installed by professional electric gate engineers. Underground gate automation could be the best style for you if you want a discreet, almost invisible electric gate motor installation and you have the budget for this more expensive option.

Safety Sensor S300

A gate opener safety sensor is a crucial component of automated gate systems designed to prevent accidents and damage by detecting obstructions in the gate's path.
These sensors, often photoelectric, use an infrared beam to monitor the area and trigger the gate to stop or reverse if something is blocking its movement. 
How it works:
  • Transmitter and Receiver:
    A safety sensor typically consists of a transmitter that emits an infrared light beam and a receiver that detects the beam.
  • Obstruction Detection:
    When an object, person, or vehicle interrupts the beam, the receiver signals the gate operator to stop or reverse the gate's movement.
  • Safety Feature:
    This mechanism prevents the gate from closing on anything or anyone, ensuring safety and preventing potential damage. 
Types of Safety Sensors:
  • Photoelectric Sensors (Photo Eyes):
    These are the most common type, using an infrared beam to detect obstructions. 
  • Safety Edges:
    These sensors are typically placed along the edge of the gate and trigger a stop or reverse when they encounter pressure. 
  • Induction Loops:
    These sensors are embedded in the ground and detect vehicles as they pass over them, triggering the gate to open or close. 
Importance:
  • Safety:
    The primary function is to prevent accidents and injuries by stopping or reversing the gate when an obstruction is present. 
  • Preventing Damage:
    By detecting obstructions, these sensors help avoid damage to the gate, vehicles, or anything else in its path. 
  • Compliance:
    Safety sensors are often required for automated gates to meet safety regulations and standards. 
Common Issues:
  • Misalignment:
    If the sensor is misaligned, the infrared beam may not reach the receiver, causing the gate to malfunction.
  • Obstructions:
    Debris, dirt, or other obstructions can interfere with the beam and trigger false alarms.
  • Sensor Failure:
    Like any electronic device, sensors can fail over time, requiring replacement.
