ZÄHL HM1 MANUAL V 1.0
Power Supply
Mains voltage and mains transformer are always potential sources of interference - consequently, we have
outsourced them to the HMP1 mains adapter.
The mains adapter also contains a standby power supply unit which delivers a stabilised low voltage. This voltage is
applied to the Power switch on the front panel of the HM1 and serves to switch on the actual mains transformer
via a relay.
Worldwide operation
The standby power supply has a wide-range input, is a purely linear design.
The mains input is equipped with one of the best interference filters available and can be set for operation on the
following voltages: 100V-110V-120V-220V-230V-240V.
The mains switch on the back of the HMP1 can be used to completely de-energise the unit.
Variable cable length
The connecting cable between the mains adapter and the main unit carries potential-separated low voltages only.
Standard length is 0,65m. Shorter and longer versions are available. Custom length upon request.
