Power supplies with accumulator 12 V - SA-01A type

Categories: ,

The SA-01A power supplies are intended for power supply of the devices for warning of the voltage presence in 6-35 kV indoor electric cells. The SA-01A source is equipped with buffer accumulator that powers the devices also in case of interruption of network voltage (220V/50Hz).

The sources provide the following information:
– Indicates the presence of network power;
– Signals optically the correct level of output voltage (over 11 V).
