Description

It is a switching power supply unit with universal input able to pro-
vide a maximum current of 20A at 25VDC. It is placed in a 19 inch
rack slot and used in combination with the PU-A0009-1 battery char-
ger in compliance with EN54-4 standard. The power supply unit fea-
tures a circuit for load distribution which allows the parallel
connection of multiple power supply units, up to a maximum of four
units. Module hot swapping is allowed (Hot Plug). On the front panel
there are: two green LEDs signaling the proper presence of input and
output voltage; a yellow LED that lights up in case of failure; and a
button for shutting the module down before hot-swapping.
