PMAC770 Multifunction Power Meter
ØSuit for LV/ HV voltage system
For low voltage system, PMAC770 direct connect up to 600VAC
For high voltage system, PMAC770 need to connect with PTs, PT ratio programmable
ØNew appearance and design
Large LCD display and button, replace AI capacitor by Tam capacitor
ØSelf-testing phase sequence error
In case of error phase sequence input, PMAC770 will display on LCD
ØReal-time measurement
True-RMS measuring parameters includes:
U, I, P, Q, S, PF, F, kWh, kvarh, demand, max./min. value,
ØDemand 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
ØMulti-tariff billing, historical data of 31 days and 12 months
2 kinds of setting modes: time zone mode and holiday mode
Time zone mode: 2 time zones in one year
Holiday mode: working days ( Mon.- Fri.) and holidays ( Sat.- Sun.)
There are 2 lists of tariff rate, each list can setup 8 periods of time in 24 hours, 4 tariff rates.
ØPower quality analysis
Harmonic analysis, crest and K factor, unbalance etc.
