208CK-D DC 12V 5A Power Supply Box

Key Features

1. Ability to connect emergency power (UPS / battery) – Allows the access control system to remain operational during a power outage.

2. Supports multiple devices simultaneously – E.g., two access control systems, electric strikes, exit buttons, or controllers, thanks to its 5A capacity.

3. NC / NO outputs – Compatibility with various types of electric locks.

4. Adjustable delay time – Flexibility in setting the lock's time from 0 to 15 seconds.

5. Built-in LED signaling – LEDs indicate the device's operating status, including mains power presence, active DC power output, and charging status.

6. Electrical protections – Protection against overloads and short circuits.

7. Support for various devices – Supports electromagnetic locks, access controllers, exit buttons, and doorbells.

8. Robust construction – Made of durable materials, ensuring long-lasting use.

Controller Components

1. Power Input A

Cables supplying power to the built-in power adapter.

• Input voltage: AC 100–260 V
• Frequency: 50–60 Hz

2. Indicator LED Power

Connector designed to connect power cables for the LEDs indicating device operation.

3. PUSH Relay Time Adjustment

Potentiometer allowing setting the relay activation time after a PUSH signal.

4. Power Output Terminals

Terminal strip for connecting external devices.

• Output voltage: 11.5–13.5 V DC
• Maximum output current: 5 A

Contact description:

• NO – Normally open contact (voltage appears after relay activation / PUSH signal).
• NC – Normally closed contact (voltage disappears after relay activation / PUSH signal).
• COM – Common relay contact (usually ground).
• +12V – Constant 12V power output.
• GND – Power ground.
• PUSH – Control input, shorting to GND activates the relay.
• CONTROL (+ / −) – 5–24 V voltage control input, operating similarly to the PUSH input.
• BATT (+/−) – Connector for connecting a 12V backup battery.

5. Output Voltage Adjustment

Potentiometer allowing adjustment of the output voltage in the range of 11.5–13.5 V DC.

6. Voltage Filtering Circuit

Section of capacitors stabilizing voltage and reducing power interference.

Power Supply Connection Diagram

1. Device Power Connection

The +12V (red wire) output from the power supply is used to power access control system devices, such as an electromagnetic lock or controller.

The GND (black wire) terminal provides a common ground for the installation. The +12V and GND wires should be connected to the appropriate power inputs of the devices.

2. Electric Strike Connection

The electric strike is connected to the +NO (brown wire) and -COM (blue wire) terminals.

Upon system activation, the NO and COM contacts close, supplying voltage and opening the door.

3. Electromagnetic Lock Connection

The electromagnetic lock should be connected to the +12V (red wire) and GND (black wire) terminals.

During system operation, the lock's power supply is temporarily cut off, allowing the door to open.

4. Exit Button Connection

The exit button should be connected to the PUSH (orange wire) and GND (black wire) terminals.

Pressing the button shorts PUSH to GND, instantly unlocking the door.

5. Battery Connection (Emergency Power)

A 12V battery can be connected to the BATT+ (red wire) and BATT- (black wire) terminals.

The battery ensures system operation in case of a mains power failure.
