Programmable value: 0...50%Pn
Pn = 3-phase active rated power = 3-phase rated voltage Un x rated current In x√3
Un: 400V
In: 1A or 5A
= 400V x5A x √3= 3464W or 400V x1A x√3= 692,8W

RS485 ModBus RTU/TCP
Address number: 1...255
Parity bit: none – even – odd
Waiting time before answer: 3...100ms
Transmission speed: 4800 – 9600 – 19200 – 38400 bit/s
ModBus message word format
1 Just for 32-bit quantities

1.8 Pulse output

(max.27 50m )
Quantity that can be coupled: active or reactive energy
Pulse weight: 1pulse/10Wh(varh) – 100Wh(varh) – 1kWh(kvarh) - 10kWh(kvarh) -
100kWh(kvarh) – 1MWh(Mvarh) - 10MWh(Mvarh)
Width of the pulse: 50 – 100 – 200 – 300 – 400 – 500ms
1.9 Harmonic Analysis
Display mode: up to the 9 th harmonic or up to the 25
Password = 2001
Level 2
2.1 Full scale current and external VT ratio
Vt =External primary/secondary VT ratio
Ct = Full scale current value
Selectable values: 1000 – 3000 – 5000A
By modifying the full scale current value and/or external VT ratio, the energy KWH
meters are automatically reset

Phase sequence diagnostic

In the software of the device we have added a specific functionality to detect and correct
many problems concerning voltage and / or current connection.
This function can be activated through password and allows to display and modify the
connection sequence provided that the following conditions are respected:
1) The neutral wire (in a 4-wire network) is connected to the right terminal
ber 1)
2) No crossings between cables connected to CT's
nals 1 and 3 - are connected some way both to CT1 and CT2)
3) The power factor is between 1 and 0,5 - Inductive load - for each phase.
