Buffer power supply module Grade 2, MSRK 13.8V/2A/OC MSRK2012

Buffered Power Supply Module – Reliable Power for Security Systems

This buffered power supply module, designated MSRK 13.8V/2A/OC, is a key component of alarm and access control systems. It provides uninterrupted power to connected devices, protecting them from the effects of mains voltage failures. A design compliant with EN50131 and EN60839-11 standards (Grade 1 and 2) guarantees high reliability and operational safety.

Construction and Application

The MSRK2012 module is designed to power devices requiring a stabilized 12V DC voltage. Its compact dimensions (86x42x73 mm) allow for easy installation inside alarm and access control system enclosures. The use of AWT5161820, AWT037 or AWT500 transformer ensures efficient energy conversion. Thanks to the built-in microprocessor-based automation system, the module monitors the battery status, performing dynamic tests and charging control.

Functionality and Benefits

• Buffered power supply: In the event of a mains voltage failure, the module automatically switches to battery power, ensuring the continuity of operation of connected devices.
• Battery protection: Built-in protection against deep discharge (UVP) and short circuit and reverse battery connection extends its lifespan.
• Status indication: LED indicators inform about the presence of mains voltage (AC), DC output status (AUX) and battery charging process (LB). Additionally, OC type EPS (mains power failure) and APS (battery failure) technical outputs are available, enabling remote monitoring of the power supply status.
• Configurable charging current: The battery charging current can be adjusted using a jumper (0.2A/0.5A), adapting it to the battery capacity and system requirements.
• High efficiency: Efficiency at 81% minimizes energy losses and reduces operating costs.
• Compliance with standards: Meeting the requirements of EN50131-6:2017 and EN60839-11:2013 standards ensures compliance with stringent safety and reliability standards.
• Expandability: Optional AWZ639 module allows changing OC outputs to relay outputs, expanding integration possibilities with other systems.
• Five-year warranty: The long warranty period demonstrates the high quality of the product and confidence in its operation for many years.

The MSRK 2012 module is a solid solution for professionals involved in the installation of alarm and access control systems, as well as for end-users looking for a reliable power source for their security devices. Thanks to its wide range of functions and protections, it provides peace of mind and protection against potential system failures.
