1.Suit for LV/ HV voltage system
For low voltage system, PMAC770 / PMAC770-DR direct connect up to 690 V (L-L) AC For high voltage system, PMAC770 / PMAC770-DR need to connect with PTs, PT ratio programmable
2.New appearance and design
PMAC770 has large LCD display and button, replace AI capacitor by Tam capacitor 3.Self-testing phase sequence error In case of error phase sequence input, PMAC770 will display on LCD
True-RMS measuring parameters includes: U, I, P, Q, S, PF, F, kWh, kvarh, demand, max./min. value,
5.Demand calculation mode is programmable
2 kinds of demand modes: fixed block and rolling block Demand cycle programmable: 5/ 10/ 15/ 30/ 60mins Slip window programmable: 1/ 2/ 3 mins
6.Power quality analysis
