The uninterruptible power supply MEg101.4 is designed for feeding the measuring and
communication devices with 12 V nominal supply voltage. Its core is a High-frequen-
cy voltage converter that converts the supply voltage with high efficiency to the output
uninterruptible DC voltage. When the supply voltage is interrupted, the power supply
delivers the output DC voltage from the internal supercapacitor for 3 sec at least or if
an external a 12 V lead-acid accumulator is connected, it will extend duration of power
supply according its capacity. If necessary, the uninterruptible power on the output of
the power supply unit can be blocked. The output of the power supply is equipped with
overcurrent protection and with a replaceable fuse on the input accessible from outside.
The accumulator circuit is also equipped with a replaceable fuses. MEg101.4 also meets
requirements of overvoltage category CAT IV / 300 V and therefore is suitable do LV dis-
tribution networks.
