Main Units

Model	Unit type	Unit category	Power supply voltage	Commu- nications
KE1-PGR1C-FLK	Power/Earth Leakage Monitor Unit	Measurement Master	100 to 240 VAC	RS-485
KE1-PVS1C-FLK	Power/Momentary Voltage Sag Monitor Unit	Measurement Master
KE1-VSU1B-FLK	Momentary Voltage Sag Monitor Unit	Function Slave
KE1-VAU1B-FLK	Voltage/Current Monitor Unit	Function Slave
KE1-CTD8E	CT Expansion Unit	CT Expansion Slave	Not required.*	---
KE1-ZCT8E	ZCT Expansion Unit	CT Expansion Slave	Not required.*	---
KE1-DRT-FLK	DeviceNet Communications Unit	Communications Slave	100 to 240 VAC	RS-485 DeviceNet

* The CT and ZCT Expansion Units cannot be used in standalone operation. They must be used together with a
Measurement Master Unit.
Power is supplied to the CT and ZCT Expansion Units from the Measurement Master Unit. Power supply wiring is not
required.
