Buffered switch-mode power supply for DIN rail Grade 2, DING2 27.6V/2A DING2-24V2A

Buffered switch-mode power supply for security systems

This buffered power supply from Pulsar, model DING2-24V2A, is a reliable power source for alarm systems, access control and video surveillance. Designed for DIN rail mounting, it ensures continuous power supply even in the event of a mains failure. This is crucial for ensuring the uninterrupted operation of devices responsible for security.

Construction and functionality

The DING2-24V2A power supply provides a stable voltage of 27.6V DC with an output current of up to 2A. Thanks to this, it can power a variety of devices, such as alarm control panels, sensors, cameras or coded locks. Built-in protections protect both connected devices and the power supply itself from the effects of short circuits, overloads and overvoltages. Additionally, the battery charging function (0.5A or 1A – selectable by jumper) guarantees that the system remains in standby mode in the event of a mains power failure. Optical LED indicators inform about the operating status of the power supply and battery.

Application and compliance with standards

The power supply meets the requirements of EN50131-6:2017 (grade 1 and 2) for intrusion and hold-up alarm systems and EN60839-11-2:2015+AC:2015 for access control systems. This means that it is a high-quality product that meets stringent safety and reliability standards. Thanks to this, installers can be sure of its correct operation in critical situations. Environmental class II (SSWiN) and I (KD) confirms its resistance to external conditions.
