Bridge Rectifier – 24VAC Input to DC Output – Maglock & Horn/Strobe Applications

This Bridge Rectifier converts 24VAC power to DC output for compatible garage door, gate, and access-control accessories that require direct-current power.

It is commonly used with electromagnetic locks (maglocks) and compatible horn/strobe warning devices, allowing accessories requiring DC power to operate from an available 24VAC power source.

The rectifier uses clearly identified wire leads for straightforward connection:

• Two Yellow Wires – 24VAC Input

• Red Wire – Positive DC Output (+DC)

• Black Wire – Negative DC Output (–DC)

Specifications

Converts 24VAC to DC

Many garage door operators, gate systems, and access-control power supplies provide 24VAC accessory power, while certain accessories require DC voltage.

This bridge rectifier converts the incoming AC power into DC output so compatible DC devices can be powered from the available 24VAC source.

Common Applications

The rectifier is designed for compatible applications including:

• Electromagnetic door or gate locks

• Maglock systems

• Horn/strobe warning devices

• Compatible access-control accessories

• Gate operator accessories requiring DC power

• Commercial door-control accessories requiring rectified DC power

Always verify the electrical requirements of the connected accessory before installation.

Wiring Identification

The rectifier uses four color-coded wire leads.

AC Input

Connect the two yellow wires to the appropriate 24VAC power source.

Because AC input does not have positive and negative polarity, the two yellow input wires are used for the AC supply.

DC Output

• Red = +DC Positive

• Black = –DC Negative

Polarity must be observed when connecting the DC-powered accessory.

Important Compatibility Note

This bridge rectifier is not a universal power supply.

It converts compatible AC input to DC output but does not replace a transformer or provide power by itself.

Before ordering or installing, verify:

• Available input voltage

• Accessory voltage requirements

• DC polarity

• Current requirements of the connected device

• Operator or control-panel wiring

• Manufacturer wiring instructions

Do not connect the rectifier to an unknown voltage source.

Ideal for Maglock Installations

Electromagnetic locks typically require DC power for proper operation.

When a compatible garage door, gate, or access-control system provides 24VAC, this bridge rectifier can provide the AC-to-DC conversion needed for an appropriate maglock installation.

The entire system must still be correctly sized for the electrical load of the lock and other connected accessories.

Horn & Strobe Applications

The rectifier can also be used with compatible horn/strobe warning accessories that require DC power.

Horn/strobe devices may be installed as part of commercial door or gate systems to provide audible or visual warning during automatic movement or other programmed conditions.

Always follow the operator and accessory manufacturer's wiring requirements.

Compact Retrofit Solution

Using a bridge rectifier can eliminate the need for a separate DC power supply in certain installations where suitable 24VAC power is already available.

This makes it useful for:

• New accessory installations

• Commercial door retrofits

• Gate-accessory installations

• Replacement of a failed rectifier

• Adding compatible DC accessories to an existing 24VAC system

If your system provides 24VAC and your compatible accessory requires rectified DC power, this bridge rectifier provides a straightforward conversion solution.

Add it to your cart today and complete your compatible maglock, horn/strobe, or access-control installation.

Before purchasing, verify:

• 24VAC input source

• Accessory DC requirements

• Required current capacity

• Correct wiring and polarity

• Operator or control-system compatibility

If you are unsure about your application's electrical requirements, verify the equipment wiring diagram before ordering.

Installation & Safety

Electrical installation should be performed by a qualified person familiar with garage door, gate, and access-control wiring.

Disconnect power before making electrical connections.

Incorrect voltage, polarity, or wiring can damage the rectifier, accessory, operator control board, or other equipment.

Never bypass required safety devices or modify operator wiring contrary to the equipment manufacturer's instructions.
