Description

The Pulsar DING2-12V2A is a professional switch-mode buffer power supply designed for uninterruptible power supply of critical security system components. The device is ideal for alarm systems, access control installations, CCTV, and any application requiring high reliability and voltage stability. The main function of the power supply is to provide 13.8V DC to receivers while simultaneously charging a lead-acid or AGM battery. In the event of a 230V mains power failure, the device switches to battery operation instantly and without interruption, ensuring system continuity.

Specification

Device advantages:

- High output voltage stability to protect sensitive electronics.

- DIN rail (TS-35) mounting, which significantly facilitates installation in standard electrical switchboards.

- Advanced battery charging system with current control to prevent damage.

- Cold start function allowing the power supply to be started directly from the battery without AC mains.

- Intelligent diagnostic system monitoring mains status, battery voltage, and circuit continuity.

- Compact housing taking up only 6 units (U) on the mounting rail.

- A series of protections against short circuits, overloads, overvoltages, and deep battery discharge.

- Dedicated OC technical outputs allowing for remote monitoring of the power status.

One of the most important advantages of this model is its full compliance with rigorous safety standards. The power supply meets the requirements of EN50131-6:2017 in Grade 1 and Grade 2, making it suitable for professional low-to-medium risk alarm systems. Furthermore, it complies with the EN60839-11-2 standard for access control systems. The device is characterized by very high energy efficiency of 90%, which translates into low heat dissipation and longer lifespan of the electronics.
