1. Technical description.

1.1 General description.

A buffer PSU is intended for an uninterrupted supply to devices requiring stabilized voltage of

24V DC (+/-15%). The PSU provides voltage of U=27,6V DC. Current efficiency:

1. Output current 9A + 1A battery charge*

2. Output current 8A + 2A battery charge*

3. Output current 6A + 4A battery charge*

Total device current + battery: 10A max

In case of power decay, a battery back-up is activated immediately. The PSU is constructed based on the

switch mode PSU, with high energy efficiency. The PSU is housed in a metal enclosure (colour RAL 9003) which

can accommodate a 2x17Ah/12V battery. A micro switch indicates door opening (front cover).

The power supply housing has space for additional modules (fuse blocks, voltage regulators and DC/DC

converters). Optional power supply configurations are available at the website: www.pulsar.pl
