OWER SUPPLY MODULE
The power supply module converts primary AC and/or DC voltage to required system
voltages. Redundant power supply cards extend system availability in case of the outage
of any power source and can be ordered separately if required

Main features of the power supply module
•
30W input
•
Maximum 100ms power interruption time: measured at nominal input voltage with nominal
power consumption
•
IED system fault contacts (NC and NO): device fault contact and also assignable to user
functions. All the three relay contact points (NO, NC, COM) are accessible to users 80V-
300VDC input range, AC power is also supported
•
Redundant applications which require two independent power supply modules can be
ordered optionally
•
On-board self-supervisory circuits: temperature and voltage monitors
•
Short-circuit-protected outputs
•
Efficiency: >70%
•
Passive heat sink cooling
•
Early power failure indication signals to the CPU the possibility of power outage, thus the
CPU has enough time to save the necessary data to non-volatile memory
