Product description

Three-phase energy meter

with removable front LCD

display unit. The same unit

can be used either as a

DIN-rail mounting or a panel

mounting energy meter. This

general purpose three-phase

energy meter is suitable for

both active and reactive

energy metering for cost al-

location but also for main

electrical parameter meas-

urement and retransmission

(transducer function). Possi-

bility to display also exported

active energy (e.g. in case of

regenerated energy in lifts or

similar applications) harmon-

ic distortion information are

available for the voltages and

the currents, up to the 15th

harmonic. An hourcounter

meter is available to link the

energy consumption to the

• Class 1 (kWh) according to EN62053-21

• Class 2 (kvarh) according to EN62053-23

• Accuracy ±0.5 RDG (current/voltage)

• Energy meter

• Instantaneous variables readout: 3 DGT

• System variables: W, var, PF, Hz, Phase-sequence.

• Single phase variables: VLL, VLN, A, PF, THD (A,V, up to

the 15th harmonic)

• Energy measurements: total kWh (imported and

exported); kvarh

• TRMS measurements of distorted sine waves (volt-

ages/currents)

• Self power supply

• Dimensions: 4-DIN modules and 72x72mm

• Protection degree (front): IP40

• Application adaptable display and programming proce-

dure (Easyprog function)

• Easy connections management

• Detachable display

• Multi-use housing: for both DIN-rail and panel mount-

ing applications

• Current inputs AV option: CT 5A

• Current inputs MV option: current sensor 333 mV (CTV

series) or ROG4K, Rogowski coil by Carlo Gavazzi

relevant working hours and

an hourcounter to link the

exported energy to produc-

tion hours. Housing for DIN-

rail mounting with IP40 (front)

protection degree. Current

measurements carried out

by means of external current

transformers transformers,

5A or 333mV (CTV series), or

ROG4K, Rogowski coil solu-

tion without external integra-

tor. Voltage measurements

carried out either by means

of direct connection or by

means of potential trans-

formers. EM210 is provided,

as standard, with a pulsat-

ing output for active energy

retransmission. In addition a

2-wire RS485 communica-

tion port is available as an

option.
