High Power supply module 230 VAC
This PCB module is galvanically separated from the mains supply and is suited for direct 230 V mains
installation. The module is a Switch Mode Power Supply (SMPS) that meets the demands for double
insulation when the calculator top is mounted. The power consumption is less than
1.7 VA/1 W.
National electricity installation requirements must be met. The 230 VAC module must be
connected/disconnected by the utility staff, whereas the fixed 230 V installation for the switch cabinet
must only be made by an authorised electrician.
If mains disappears, this SMPS will keep the meter running for a few seconds.

High Power supply module 24 VAC
This PCB module is galvanically separated from the 24 VAC mains supply and is suited for industrial
installations with joint 24 VAC supply and individual installations supplied from a separate 230/24 V safety
transformer in the switch cabinet. The module is a Switch Mode Power Supply (SMPS) that meets the
demands for double insulation when the calculator top has been mounted. The power consumption is less
than
1.7 VA/1 W.
National electricity installation requirements must be met. The 24 VAC module must be
connected/disconnected by the utility staff, whereas installation of 230/24 V in the switch cabinet must
only be made by an authorised electrician.
The module is specially suited for installation together with a 230/24 V safety transformer, e.g. type 66-99-
403, that can be installed in the switch cabinet before the safety relay. When the transformer is used the
power consumption will be less than 1.7
W for the entire meter including the 230/24 V transformer. If
mains disappears, this SMPS will only keep the meter running for a few seconds.
