Buffered switch-mode power supply Grade 3, HPSG3 27.6V/2A/2x17Ah HPSG3-24V2A-C

Reliable power supply for alarm and access control systems

The buffered impulse power supply Grade 3, HPSG3 27.6V/2A/2x17Ah is a key element ensuring the continuity of security systems. The device, manufactured by Pulsar, is designed to work with batteries up to 17Ah in capacity, guaranteeing long-term power supply in the event of a power failure. Its construction meets the requirements of EN50131-6 (degree 1-3) and EN60839-11 standards, which confirms its high quality and reliability.

Functionality and safety

The HPSG3 power supply is not only a stable power source but also advanced protection features. It has built-in protection against overload (SCP), short circuit (OVP), undervoltage (UVP) and overvoltage (OLP), as well as against opening the housing and detachment from the wall (tamper). Additionally, the LED optical signaling informs about the operating status of the device. The battery charging current is 0.8A, which ensures optimal charging and longer battery life. It is worth noting the efficiency of the device reaching 83%, which translates into energy savings.

Installation and application

The HPSG3 power supply is designed for surface mounting in a metal housing (RAL 7016 color - gray). Its dimensions - 314 x 408 x 190 mm - allow for easy adaptation to different spaces. The device is used in alarm systems, access control systems and anywhere where a reliable emergency power supply is required. A manual START button allows you to start the power supply from the battery if necessary. Technical OC outputs (EPS, PSU, APS) allow for remote monitoring of the power supply and battery status.
