Grade 3 buffered switch-mode power supply, HPSG3 13.8V/10A/65Ah/LCD HPSG3-12V10A-E-LCD

Buffered power supply, switch-mode Grade 3 – reliable power supply for security systems

This Grade 3 switch-mode buffered power supply, with a voltage of 13.8V and a current of 10A, with a 65Ah battery, is a solid solution for alarm and access control systems. Designed in accordance with EN50131-6 and EN60839-11 standards, it provides uninterrupted power even in the event of a mains failure. Equipped with a clear LCD display, it allows monitoring of key operating parameters.

Design and functionality

The HPSG3-12V10A-E-LCD power supply has been designed with reliability and ease of use in mind. Its design allows for surface mounting, and the housing is protected against opening (tamper). Built-in protections (SCP, OLP, OVP, UVP) protect both the power supply itself and the connected devices from damage caused by overvoltages, overloads or short circuits. Additionally, it has signaling of AC mains failure, power supply failure and battery status using OC outputs.

The power supply is compatible with batteries with a capacity of 17Ah to 65Ah. The battery charging efficiency is 2.6A. This ensures optimal battery maintenance in a ready-to-use condition. Remote monitoring via LAN or RS485 network (requires appropriate modules) allows for continuous monitoring of the power supply and battery status from anywhere.

Applications and compliance with standards

The HPSG3-12V10A-E-LCD power supply is ideal for systems:

• Alarm systems (SSWiN) – meets the requirements of EN50131-6 standard in environmental class II and degree 1, 2 and 3.
• Access control (KD) – compliant with EN60839-11-2 environmental class I.
• Fire protection systems
• Building automation systems

Equipped with an LCD panel allowing reading of electrical parameters (voltage, current) and the status of technical outputs. It has three access levels protected by a password and an operating memory. The START function allows manual activation of the power supply from the battery. The power supply is adapted to work in a wide range of AC input voltage (200-240V). The efficiency of the device reaches 85%.
