The WB-MAP12(H) counter can be powered from any of the connected phases. For data exchange via Modbus to the controller, you must also apply power to the connector the front end. It is possible to power the meter only from the interface part. In this case, the AC parameters are not measured (the voltage across all channels will be displayed as 0 V), but the current values obtained from the current transformers will be measured correctly. | The WB-MAP12(H) counter can be powered from any of the connected phases.
