Description

The Pulsar DING2-12V2A is a professional switched-mode buffer power supply designed for the uninterruptible power supply of key security system components. The device is perfect for alarm systems, access control, CCTV installations, and any application requiring high reliability and voltage stability. The primary function of the power supply is to provide 13.8V DC voltage to receivers while charging a lead-acid or AGM battery. In the event of a 230V mains failure, the device switches instantly and seamlessly to battery operation, ensuring continuous system operation.

Specification

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 (Grade 1 and Grade 2), making it suitable for professional low-to-medium risk alarm systems. It also complies with the EN60839-11-2 standard regarding access control systems. The device features a very high energy efficiency of 90%, which translates into low thermal losses and longer electronics lifespan.

Device advantages:

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

- High output voltage stability to protect sensitive electronics.

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

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

- Compact housing occupying only 6U units on the mounting rail.

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

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

- A range of protections against short-circuits, overloads, surges, and deep battery discharge.
