Power supply 55W 13.8V, 5V, 13.4V ADD-55A

Buffer power supply with battery charging output

This 55W industrial power supply is a reliable energy source for systems requiring stable power and the ability to maintain operation in the event of a power failure. It is ideal for monitoring systems, access control, alarms, and anywhere continuous operation is required. Using it in conjunction with a battery allows you to create a UPS (uninterruptible power supply) system.

Functionality and safety

The ADD-55A power supply offers three outputs: 13.8V, 5V, and 13.4V, making it a versatile solution for various applications. Short-circuit, overload, and overvoltage protection ensure safe operation of devices and protect against damage. Additional protection against deep battery discharge (in selected models) extends its lifespan. Output voltage adjustment in the range of +/-10% allows for precise adjustment of parameters to the needs of specific devices.

Construction and parameters

The power supply is designed to operate in a wide temperature range – from -10°C to +60°C – ensuring its reliability even in harsh environmental conditions. The housing made of ABS plastic is durable and resistant to mechanical damage. Compact dimensions (159x97x38mm) facilitate installation, and cooling is done by natural air circulation, eliminating the need for additional fans. The power supply is characterized by high efficiency at 71%. It accepts input voltage in the range of 88-264VAC and 124-370VDC. The output current is 3.5A at 5V and 0.23A at 13.8V/13.4V.
