⚫ Reactive energy (VARh) ±1% of range maximum
⚫ Total harmonic distortion 1% up to 31st harmonic
⚫ Response time to step input 1s, typical, to >99% of final reading, at 50 Hz.
*Auxiliary Supply
Two-way fixed connector with 2·5mm2 stranded wire capacity.
85 to 275V a.c. 50/60Hz ±10% or 120V to 380V d.c. ±20%. Consumption < 10W.
Interfaces for External Monitoring
Three interfaces are provided:
⚫ an RS485 communication channel that can be programmed for Modbus RTU protocol
⚫ an output indicating real-time measured energy.(configurable)
⚫ an pulse output 3200imp/kWh (not configurable)
The Modbus configuration (Baud rate etc.) and the pulse output assignments (kW/kVArh) are
configured through the Set-up screens.
Pulse Output
The unit provides two pulse outputs. Both pulse outputs are passive type.
Pulse output 1 is configurable. The pulse output can be set to generate pulses to represent total
kWh or kVarh.
The pulse constant can be set to generate 1 pulse per:
0.01 = 10 Wh/VArh
0.1 = 100 Wh/VArh
1 = 1 kWh/kVArh
10 = 10 kWh/kVArh
100 = 100 kWh/kVArh
1000=1000 kWh/kVArh
Pulse width: 200/100(default)/60ms
Pulse output 2 is non-configurable. It is fixed up with total kWh. The constant is 3200imp/kWh.
RS485 Output for Modbus RTU
For Modbus RTU, the following RS485 communication parameters can be configured from the
Set-up menu:
Baud rate 2400, 4800, 9600, 19200, 38400
Parity none (default)/odd/even
Stop bits 1 or 2
RS485 network address nnn – 3-digit number, 001 to 247
Modbus™ Word order Hi/Lo byte order is set automatically to normal or reverse. It cannot
be configured from the set-up menu.
