What it monitors
- Four-quadrant and complex-rate energy with internal temperature monitoring
- Real-time demand plus maximum demand with time stamp for current, P, Q, S
- Monthly and previous-month extreme values for U, I, P, Q, S, PF and frequency
- Voltage and current unbalance, phase angles, vector diagram and crest / K-factor
- Dual RS485 copies the master-station data, so no data exchange gateway is needed
- Modbus-RTU or DL/T 645-2007 register map supplied on request
Before you request a quote
- CT primary rating and burden, or 1 A / 5 A secondary
- Auxiliary supply: AC/DC 85-265 V or the 115-415 V option
