Pulsar HPSB-24V5A-C buffer power supply in enclosure, 27.6 V, 5 A, battery 2x17 Ah

Pulsar HPSB is a switch mode buffer power supply that provides uninterrupted stabilised voltage (13.8 V, 27.6 V or 54 V DC) for alarm, access control and CCTV devices. The enclosure holds a battery that the unit charges and maintains; if the mains fails, supply continues from the battery.

The unit is protected against short circuit, overload, overvoltage and surges, has deep discharge protection and protects the battery output against short circuit and reverse connection. The charging current is jumper selectable, a tamper switch monitors the enclosure and LEDs show the status. Efficiency is up to 90%.
