Power supply 155W 13.8V 11.5A, 13.3V 0.5A AD-155A

Buffered power supply for security and automation systems

This 155W industrial power supply is designed to reliably power devices requiring a stable voltage, such as monitoring, access control, or alarm systems. Its design also allows it to operate as an uninterruptible power supply (UPS) in conjunction with a battery, ensuring continuous operation in the event of a mains power failure. The use of protections against overload, short circuit, and battery discharge guarantees the safety of both connected devices and the power supply itself.

Construction and functionality

The power supply is characterized by two outputs – one at 13.8V (11.5A) designed to power standard devices, and the other at 13.3V (0.5A) dedicated to battery charging. This solution allows for continuous system operation even during power outages. Adjustable output voltage in the range of +/- 10% allows you to adapt the parameters to the specific requirements of connected receivers. High energy efficiency (up to 80%) translates into lower energy losses and lower operating costs.

Safety and application

The power supply has a number of protections, including against short circuit, overvoltage, and overload, which minimizes the risk of damage and ensures long-term reliability. It meets the safety standards UL60950-1 and TUV EN60950-1, confirming its high quality and compliance with European standards. The possibility of mounting on a DIN rail (using appropriate brackets) facilitates installation and integration with existing systems. Designed for installation inside powered devices, as well as for professional applications. Remember to properly ground the device to ensure full safety of use.
