Power supply PULSAR PSG2-24V3A — built-in switching PSU 27.6V / 3A

PULSAR PSG2-24V3A is a built-in switching power supply that provides a stabilized 27.6 V DC output with a maximum current of 3 A. Designed for mounting inside enclosures and cabinets, the unit uses switching topology to deliver continuous, efficient power to low-voltage electronic equipment. Typical applications include access control systems, alarm panels, CCTV modules and other devices that require a steady DC supply. The compact form factor and built-in design allow integration into security and automation installations where space and reliable voltage regulation are important.

Advantages

The switching design provides high efficiency and reduced heat generation compared with linear supplies, enabling reliable continuous operation at the rated 3 A output. Built for embedded mounting, the PSU offers stable voltage regulation and is optimized for powering multiple low-current devices within a single enclosure. Its compact construction simplifies installation inside control cabinets and security housings while maintaining consistent output under varying load conditions.

Suitable for

• Access control systems (controllers, readers, electric locks)
• Alarm and intrusion panels
• CCTV cameras and peripheral modules
• Low-voltage automation and monitoring equipment

Key specifications

• Output voltage: 27.6 V DC (stabilized)
• Maximum output current: 3 A (continuous)
• Topology: switching power supply
• Intended mounting: built-in / embedded in enclosure
• Application: low-voltage electronic devices and security systems

How to use

Install the PSU inside a suitable enclosure following the device’s mounting provisions and ensuring adequate clearance for ventilation. Connect the AC input per local electrical standards and wire the DC output to the target devices, observing polarity. Verify that the combined current draw of connected devices does not exceed the 3 A continuous rating. After powering up, check the output voltage to confirm stable 27.6 V DC and monitor for normal operation under expected load conditions.

Usage recommendations

Place the power supply in a dry, ventilated enclosure and avoid installing it near heat sources. Ensure wiring and protective devices (fuses, circuit breakers) match local regulations and the PSU’s current rating. For installations powering several devices, calculate total current consumption and allow margin below the 3 A limit to maintain reliability and temperature stability.
