1.1. General description.
Switch mode buffer power supply units PWB are intended for continuous power supply to devices that require
stabilised voltage of 52 V (
e.g.
PoE power systems, PoE switches
).
Rozwiązanie posiada dodatkowy atut w
postaci stabilizacji napięcia wyjściowego bez względu na stan naładowania baterii. Built-in DC/DC converter allows
to reduce costs of installation by reducing number of required batteries. Additional advantage is output voltage
stabilisation regardless of battery charge status.

In case of power failure, a battery back-up is activated immediately. PSU is constructed based on switch
mode PSU, with high energy efficiency. In addition, they are equipped with a START button allowing them to
be started from the battery (e.g. in the absence of mains power).
