Power supply PULSAR PSG2-24V2A 27.6V 2A enclosed switching PSU for built-in installation

PULSAR PSG2-24V2A is an enclosed switching power supply designed for built-in installation, delivering a regulated 27.6 V DC output with a maximum current of 2 A. The compact metal housing and fixed mounting arrangement allow integration inside distribution cabinets, security enclosures and equipment racks. The PSU provides stable voltage for low-voltage devices such as CCTV cameras, access control modules and alarm control panels and includes protection against short-circuit and overload conditions to maintain reliable operation in typical security and automation installations.

Advantages

The unit offers a compact footprint suitable for confined installation spaces while maintaining stable regulation at full load. Built-in short-circuit and overload protection reduces the risk of system damage and simplifies integration with battery-backed systems. The enclosed design minimizes exposure to dust and accidental contact, and the switching topology ensures relatively high conversion efficiency and lower heat generation compared with linear alternatives.

Suitable for

• Powering CCTV cameras and video transmission equipment
• Supplying access control panels, card readers and electric door releases
• Feeding alarm control panels, sensors and auxiliary security devices
• Integration inside cabinets, racks and equipment enclosures for building automation

Key specifications

• Output voltage: 27.6 V DC
• Maximum output current: 2 A
• Output type: Regulated switching DC output suitable for low-voltage devices
• Protection: Short-circuit and overload protection
• Enclosure: Compact enclosed housing for built-in installation
• Cooling: Convection cooling through housing

How to use

Install the PSU inside a suitable cabinet or enclosure using the built-in mounting points and ensure adequate ventilation around the housing. Connect the AC input to an appropriately rated mains supply following local electrical regulations and connect the DC output to the target device(s), observing correct polarity. If used in systems with backup batteries, follow the system wiring diagram to include battery charging or switchover circuits as required. Verify output voltage with a multimeter before connecting sensitive equipment.

Usage recommendations

Locate the power supply in a dry, well-ventilated space away from direct heat sources. Do not exceed the rated 2 A output current; account for inrush currents of connected devices. Periodically inspect terminals for secure connections and keep vents clear of dust. For installations in safety-critical systems, adhere to local codes and consider adding external fusing or monitoring where required.
