Buffered switch-mode power supply for built-in Grade 2, PSG2 13.8V/1A PSG2-12V1A

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

The PSG2 13.8V/1A buffered switch-mode power supply is a device designed to provide uninterrupted power to alarm systems (I&HAS) and access control systems (ACS). The power supply design meets the requirements of EN50131-6:2017 and EN60839-11:2013 standards, class 1, 2 and II, which guarantees its high quality and reliability in critical applications. Thanks to the stabilized output voltage of 13.8V DC (±15%), it is ideally suited for powering devices requiring precise voltage.

Construction and functionality

The PSG2 power supply is characterized by a compact design for installation with dimensions of 110 x 78 x 36 mm. It offers an output current of 1A at 13.8V DC and a battery charging current of 0.2A. Built-in SCP (short-circuit protection), OLP (overload protection), OVP (overvoltage protection) and UVP (undervoltage protection) protect both the power supply itself and the connected devices. Additionally, it has technical relay-type outputs EPS (AC power failure) and APS (battery failure), enabling remote monitoring of the power supply status. High efficiency at 86% translates to lower energy losses and lower operating costs.

Key features and benefits

• Compliance with standards: Meeting the requirements of EN50131-6:2017 and EN60839-11:2013 standards ensures compliance with the requirements of security systems.
• Reliable operation: Stabilized output voltage and built-in protections guarantee the continuity of operation of connected devices.
• Status signaling: EPS and APS outputs allow for remote monitoring of the power supply status and quick response in the event of a failure.
• Compact dimensions: Allow for easy installation in alarm and access control system enclosures.
• High efficiency: Reduces energy losses and lowers operating costs.
• Automatic battery testing: An automatic battery status test is performed every 5 minutes, which increases the reliability of the system in the event of a mains power failure.
• Possibility of mounting on a DIN rail: Allows convenient mounting in control cabinets (DIN2 bracket - optional required).
• Long warranty: 2 years from the date of manufacture confirms the high quality of the product.

The PSG2 power supply is a solid solution for professionals installing security systems and for end-users looking for a reliable power source for their devices. Its versatility and rich equipment make it an ideal choice for both new installations and modernization of existing systems.
