Grade 2 buffered switch-mode power supply, HPSG2 13.8V/10A/40Ah HPSG2-12V10A-D

Buffered switch-mode power supply – reliable power supply for security systems

This advanced buffered power supply, designed for alarm systems (SSWiN) and access control (KD), provides uninterrupted power to devices operating at 12 V DC. Designed in accordance with EN50131-6:2017 and EN60839-11:2013 standards, it guarantees high reliability and safety of operation. Its construction, compliant with protection class 2, makes it an ideal choice for both professional installers and end-users looking for a solid solution.

Performance and functionality

The HPSG2-12V10A-D power supply offers an output power of up to 138 W with a current of 10 A. High efficiency (up to 89%) translates into minimal energy losses and reduced operating costs. The available START function allows manual switching of the power supply to the battery, which is particularly useful in emergency situations or during maintenance. The battery charging current can be easily adjusted using a jumper, choosing between 1A and 4A values. LED optical signaling informs about the operating status of the power supply and battery.

Safety first

The applied protections protect both the power supply itself and the connected devices. These include: short-circuit protection (SCP), overload protection (OLP), overvoltage protection (OVP), and deep discharge protection (UVP). Additionally, the built-in battery circuit continuity control and dynamic battery test ensure its proper operation in critical situations. Anti-tamper protection of the housing opening further increases the security level of the system. EPS and APS technical outputs signal network power failure and battery failure, respectively, enabling a quick response to potential problems.
