Switching buffered power supply HPSB 27.6V/10A/2x40Ah HPSB-24V10A-D

Buffered power supply – reliable power supply for security and automation systems

This pulsed buffered power supply, with an output voltage of 27.6V DC and a current of 10A, is an ideal solution for alarm systems, access control, video surveillance and other devices requiring stable and uninterrupted power. The device ensures smooth operation even in the event of a mains power failure, automatically switching to battery power. The power supply design allows for the installation of batteries with a capacity of up to 40Ah, guaranteeing long-term power backup.

Construction and functionality

The power supply is characterized by high efficiency (up to 87%), which translates into energy savings. The metal housing (DC01 steel, 1mm, RAL9003 – white color) provides durability and resistance to mechanical damage. A built-in microswitch (tamper) signals an attempt to open the housing, increasing the level of security. Three battery charging current levels are available (1A/2A/4A), allowing you to adjust the parameters to specific needs and the type of batteries used. The use of impulse power supply modules ensures high energy efficiency.

Safety and compliance with standards

The power supply is equipped with a number of protections: SCP (short-circuit), OLP (overload), OVP (overvoltage), UVP (deep discharge protection) and tamper (against opening the housing). It meets the requirements of EN50131-6:2017 (environmental classes 1, 2 and II) and EN60839-11:2013 (environmental classes 1, 2 and II), confirming its high quality and reliability. Fuses protect against short circuits and overvoltages. LED signaling informs about the operating status of the device. Surface mounting facilitates installation in various locations.
