5. Measuring Parameter

5.1 Current

PMAC201HW support Max. 5000/0.1A AC current input, please avoid secondary circuit

open during connecting, or high voltage caused by excitation effect will makes human

injured or instrument damaged.

The current can be configured as A/B/C voltage at random.

5.2 Voltage

PMAC201HW directly measures voltage under 330V (phase to phase)/570V (line-line)

without external PT. It can set as Y connection or Δ connection.

5.3 Active Power

PMAC201HW can separately measure active power of each circuit in 12 circuit x single

phase, or total active power of each circuit in 4 circuit x 3 phase.

11

Attention

During connecting, please pay attention to the correspondence of

voltage and current sequences, otherwise, it will causes power

calculating error; Meanwhile, make sure +/- of CT and meter’s

terminals, otherwise, the value will be negative.

5.4 Reactive Power

PMAC201HW can separately measure reactive power of each circuit in 12 circuit x

single phase, or total reactive power of each circuit in 4 circuit x 3 phase.

5.5 Apparent Power

PMAC201HW can separately measure apparent power of each circuit in 12 circuit x

single phase, or total apparent power of each circuit in 4circuit x 3 phase.

5.6 Power Factor

PMAC201HW can separately measure power factor of each circuit in 12 circuit x single

phase, or total power factor of each circuit in 4 circuit x 3 phase. The measuring rage is

from -1.000 to +1.000. As same as power measuring, the power factor’s calculated

value is reflected by connection of CT and meter’s terminals.

12

13

5.7 Demand Calculate

PMAC201HW can separately measure current demand, active power demand of each

circuit in 12 circuit x single phase, and total active power demand of each circuit in 4

circuit x 3 phase. Demand calculate is fixed window. Calculate interval 15min.

5.8 Energy Calculate

PMAC201HW can separately measure input/output active energy, input/output reactive

energy of each circuit in 12 circuit x single phase, and total input/output active energy,

total input/output reactive energy of each circuit in 4 circuit x 3 phase.

5.9 Multi-tariff Calculate

PMAC201HW supply multi-tariff function, each tariff list can be set max. 8 periods in one

day and 4 different tariff (F1, F2, F3, F4 means 4 kinds of tariff)

Customer can set 4 season in the whole year (12 month). Each season can set

independent multi-tariff mode, distinguish working day and holiday day.

6. Event Record

6.1 Power ON/OFF Event

PMAC201HW records ON/OFF event of load signal, depth: 40 records, in chronological

sequence, record content includes: event (power on or off) occurrence time, last event

duration. The ON/OFF critical value can be set from 0.01 to 100A

14

For instance: event logging records when phase A current under critical value, record

includes: phase, event (power on or off), occurrence time, last event duration.

Meanwhile, PMAC201HW supports power ON/OFF event records clearing.

6.2 Parameter Revising Event

PMAC201HW records parameter revising event, depth: 10 records, in chronological

sequence, record content includes: phase, parameter, revising time, occurrence time,

primary value and revised value. Revising without any parameter modified won’t be

recorded.

For intense: Change PT ratio from 100 to 200, the PT ration value (revised item),

revised time, primary value100, revised value 200 all will be recorded.

Meanwhile, PMAC201HW supports resetting function for parameter revising event.

6.3 Data Freezing/ Load Record

PMAC201HW offers a 64M bits - bulk memory to enlarge storage space.

Notice:(1) Sudden power fail will cause at most 1 hour data losing.

(2) Data will be saved normally after electrified 1 hour continuously.

For instance: To check the 2nd record on 2012-03-28, write 0, 12, 3, 28, 2, 1 one by one

to 47001-47006 registers, then read this record from 47007 – 47052 registers.
