PMAC770 buy digital panel multi-function meter with Following Features

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.

ØOptional module and upgradeable

Pluggable in option module, support online upgrade

ØSetpoint alarm

Under/ over limit alarm, monitoring objects include: U, I, PF, F, THD, unbalance

If any parameters is over or under limit and persists over the specified time, PMAC770 will record the event, and trip relay output signal.

ØHigh accuracy

Active energy: according to IEC62053-22, class 0.5s

Reactive energy: according to IEC62053-23, class 2

ØSmall size and thin style

Panel: 96x96x13.5mm Cut-out: 90x90mm,

Depth: 45.1mm (basic unit) + 21.5mm (optional module)

ØStandard IEC62053-22/ 23, CE. KEMA
