Grade 2 buffered switch-mode power supply, HPSG2 13.8V/7A/17Ah HPSG2-12V7A-C

Buffered Switch-Mode Power Supply – Reliable Power for Security Systems

This Grade 2 buffered switch-mode power supply, with an output voltage of 13.8V and a current of 7A, is designed to provide uninterrupted power to devices requiring stabilized voltage. It is ideal for alarm systems (SSWiN) and access control (KD), meeting the standards of EN50131-6:2017 (Grade 1 and 2) and EN60839-11:2015+AC:2015. Its solid construction and advanced protection features guarantee long-lasting and trouble-free operation.

Functionality and Application

This power supply is designed to operate in both buffered and battery modes, offering flexibility in system configuration. The battery charging current can be adjusted using a jumper (1A or 2A), allowing it to be adapted to the capacity and type of battery (recommended 17Ah/12V battery). The START function allows manual switching to battery power, which is useful during testing or maintenance. Equipped with two technical relay-type outputs (EPS – AC power failure, APS – battery failure) enables remote monitoring of the power supply status.

Safety and Protection

The implemented protections, such as SCP (short-circuit protection), OLP (overload protection), OVP (overvoltage protection), UVP (undervoltage protection), and tamper (housing opening detection), ensure protection for both the power supply itself and the connected devices. Additionally, dynamic battery testing and monitoring of its voltage and charging status allow for early detection of potential problems. The metal housing provides durability and mechanical resistance. The IP20 protection class protects against accidental contact.
