Feature
ØSuit 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 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, PMAC**0 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/
*0/ *5/ *0/ *0mins
Slip window programmable: 1/ 2/
3 mins

*1 days and *2 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 *4 hours, 4 tariff
rates.
ØPower quality
analysis

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, PMAC**0 will
record the event, and trip relay output signal.
