Main Features:

Power supply unit PS-103-20A is intended for supply various
ship and industrial equipment with the unstabilized voltage of
a direct current 24 V.

Small overall dimensions and easy-to-use fastenings provide
its simple placing and installation

For the devices requiring power supply of the higher power,
"Unicont SPB" company produces more powerful
modifications of this device: PS-103-20A (500 W) and PS-
103-12A (300W)
