Buffered switch-mode power supply for installation Grade 2, PSG2 13.8V/5A PSG2-12V5A

Reliable buffer power supply for security and access control systems

The PSG2-13.8V/5A pulse buffer power supply is an indispensable element of burglar alarm and access control systems (SSWiN and KD). It provides a stable power supply to devices requiring 12V DC, guaranteeing their continuous operation even in the event of a mains power failure. Grade 2 construction confirms its high quality and reliability, and compliance with EN50131 and EN60839 standards makes it an ideal choice for professional installers.

Construction and functionality

The PSG2-13.8V/5A power supply is distinguished by its compact built-in design, with dimensions of 159 x 98 x 42 mm. It offers an output current of 5A at a voltage of 13.8V DC, as well as a battery charging function with the possibility of selecting a charging current of 1A or 2A. Built-in protections – SCP (short-circuit), OLP (overload), OVP (overvoltage) and UVP (deep discharge protection) – protect both the power supply itself and the connected devices. Additionally, it has technical relay outputs EPS (AC power failure) and APS (battery failure), allowing for remote monitoring of the power supply status.

Advantages for the installer and end user

• Versatility: Application in alarm and access control systems.
• Safety: Comprehensive protection against damage and failures.
• Reliability: Grade 2 construction and compliance with standards ensure long-term and stable operation.
• Flexibility: The ability to choose the battery charging current adapts the power supply to specific needs.
• Feedback: EPS and APS outputs allow for quick response in case of power supply problems.
• Easy installation: Designed for built-in installation, optional DIN rail mounting (requires bracket).
• High efficiency: Efficiency level of 87% translates into energy savings.
• Automatic battery testing: Regular tests every 5 minutes ensure the system is always ready.

Technical specifications in practice

The PSG2-13.8V/5A power supply has been designed to meet the requirements of modern security systems. High energy efficiency minimizes energy losses, and a solid construction ensures long-term, trouble-free operation. The possibility of connecting an external LED optical signaling set LED PKAZ168 further increases the functionality of the device, allowing for quick identification of any problems. Thanks to this, the installer can be sure that the system will operate reliably for a long time, and the end user – that their property is adequately protected.
