Buffer power supply 120W 27.6V 3.4A, 27.6V 1A LAD-120B

Buffered power supply for security and monitoring systems.

The LAD-120B buffered power supply from MEAN WELL is a reliable power source designed for use in alarm systems, access control, video surveillance and other applications requiring uninterrupted power. The device provides a stable output voltage of 27.6V with a maximum current of 3.4A, and also has an additional 1A output for battery charging. This ensures that in the event of a mains power failure, the system can continue to operate powered by the battery.

The power supply is characterized by a wide range of input voltages (90-264VAC, 127-370VDC), making it a universal solution in various installations. It has built-in protection against short circuits, overloads, overheating and overvoltages, which guarantees safety for both connected devices and the power supply itself. Additionally, the device status indication (AC OK, battery connection, battery charge status) facilitates diagnostics and system monitoring.

Key features and benefits:

• Two outputs: One main (27.6V/3.4A) and a second for battery charging (27.6V/1A) – allows you to create an emergency power system (UPS).
• Wide input voltage range: Compatibility with various electrical networks around the world.
• High efficiency: Achieves an efficiency of 88%, which translates to lower energy losses and lower operating costs.
• Built-in protections: Provide protection against damage and extend the life of the device and connected receivers.
• Status indicators: Allow for quick identification of problems and effective system diagnostics.
• Output voltage adjustment: Possibility of precise adjustment of the voltage to the requirements of specific devices (-20~+5%).
• Cold start capability: Allows the power supply to be started without a connected battery.
• Compact dimensions: 1U profile housing makes it easy to mount in limited spaces (159x97x30mm).
• Three-year warranty: Confirms the high quality and reliability of the product.

The LAD-120B power supply is a solid and efficient solution for professionals and users who value the reliability and safety of power systems. It will work well in both new installations and in the modernization of existing security and video surveillance systems. Its versatility makes it a product worth recommending to installers and end customers looking for a proven solution in the field of buffered power supply.
