1/ CHARACTERISTICS
e uninterruptible power supplies Supply MEg101.3a and Supply MEg101.3b are desi-
gned to supply electrical power to the PQ monitor MEg39 set. eir fundamental part
consists of a HF voltage converter converting the supply voltage into 12 VDC output voltage
with high eciency. When the supply voltage is interrupted, the DC output voltage is de-
livered by the internal rechargeable battery repeatedly for a period of 1 minute. In case of
need, the delivery of electric power at the output of the power source can be blocked up. e
power supplies are equipped with overcurrent protection at their outputs and with a fuse at
the input that is accessible from outside.
