Find the answer to commonly asked questions about the PM8000 as well as user/installation guides for that meter.

Resolution

What are the control power input requirements?
120 to 300 V DC ± 10%
50/60 Hz ± 10% : 90 to 415 V ± 10%400 Hz: 90 to 120 V ± 10%
Burden:
    Meter only: 18VA max at 415V AC, 6W at 300V DC
    Fully optioned Meter: 36 VA max at 415V AC, 17W at 300V DC

What is the rating of the current inputs?
Nominal 5 A (Class 0.2S) or 1 A (Class 0.5S)
Measured current: 50 mA to 10 A
Starting current: 5 mA
Withstand: 20 A continuous, 50 A @10 sec/hr, 500 @ 1 sec/hr
Impedance: 0.3 mΩ
Burden: 0.024 VA at 10 A

What are the voltage inputs rated at?
Measured voltage: 57 to 400 V L-N / 100 to 690 V L-L (Wye) or 100 to 600 V L-L (Delta or Wye with unearthed neutral)
Frequency: 50/60 Hz ± 15%,
400 Hz ± 10%
Overload: 600 V L-N or
1035 V L-L

What are the options to connect the PM8000 via RS485?
The PM8000 can be connected via RS485 2 wire. The remote display does not have the option to connect RS485 4 wire as the PM800 does.
in order to communicate RS485 4-wire, a 2 to 4 wire converter needs to be used.

What are the maximum number of digital and analog inputs on the PM8000 series?
27 Digital inputs
16 Analog inputs

What is the difference between PM8243 and PM8244?
PM8243 is DIN rail meter with no display.
PM8244 is DIN rail meter with remote display. So Basically PM8244 is a PM8243 + remote display (PM89RD96)
