The EQ series are meters for single

phase and three phase metering. The

EQ series meters are mounted on a

DIN rail and are suitable for installation

in distribution boards and small

enclosures such as consumer units.

Inputs and outputs*

The EQ series support two inputs and two

outputs in a fixed configuration. Inputs can be

used for counting pulses from e.g. a water meter,

or reading status from external devices. Outputs

can be used as pulse outputs or controlling

external apparatus like a contactor or an alarm

(connected via an external relay).

Approvals*

The EQ series meters are type approved

according to IEC and they are both type approved

and verified according to MID. MID is the

Measuring Instruments Directive 2004/22/EC

from the European Commission. MID type

approval and verification is mandatory for meters

in billing applications within EU and EEA. The

type approval is according to standards that

covers all relevant technical aspects of the meter.

These include climate conditions, electromagnetic

compatibility (EMC), electrical requirements,

mechanical requirements and accuracy.

The EQ series are suitable in applications where

there is a need for reliable energy measurements

and where space is limited.

General features

The EQ series meters are versatile meters for

many applications and installations. Navigating

the meter is easily done via the push-buttons

below the display. To configure the meter

settings, the set button must be accessed and

this button is protected against unauthorized use

when the transparent lid on the front of the meter

is closed and sealed. The power consumption of

the meter is very low, less than 0.8 VA.

Communication*

Data from the EQ series meters can be collected

via pulse output or serial communication. The

pulse output is a solid state relay that generates

pulses proportionally to the measured energy.

The meters can also be equipped with built-in

serial communication interfaces for M-Bus or

Modbus (RS-485).

Instrumentation*

The EQ series meters support reading of

instrument values. A large number of electrical

properties can be read. Depending on version of

the meter the following data is available:

• Active power

• Apparent power

• Reactive power

• Current

• Voltage

• Frequency

• Power factor
