Feature

1. Suit for LV/ HV voltage system
For low voltage system, PMAC**0 direct connect up to **0VAC
For high voltage system, PMAC**0 need to connect with PTs, PT ratio programmabl

New appearance and design
PMAC**0 has large LCD display and , replace
AI capacitor by Tam capacitor

Self-testing phase sequence error In case of error phase sequence ,PMAC**0 will display on LCD

Real-time measurement
True-RMS measuring parameters includes:
U, I, P, Q, S, PF, F, kWh, kvarh, demand,
max./min. value,

Demand calculation mode is programmable
2 kinds of demand modes: fixed block and rolling block
Demand cycle programmable: 5/ *0/ *5/ *0/ *0mins
Slip window programmable: 1/ 2/ 3 mins

Power quality analysis
Harmonic analysis, crest and K factor, unbalance etc.
