Description

The B series EQ meter is a three phase meter, is mounted on DIN rail and suitable for installation in distribution boards and small enclosures such as consumer units.

The B series are suitable in applications where there is a need for reliable energy measurements and where space is limited.

General features

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 B 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 are also equipped with built-in serial communication interface for Modbus RTU (RS-485) and can also be set to
communicate over the new EQ bus with the new gateway G13. All meters in the B series come with an infrared port for communication with an external Serial Communication Adapter (SCA) such as the KNX adapter.

Instrumentation

The B series meters support reading of instrument values.
A large number of electrical properties can be read including: 

  • Active power
  • Apparent power
  • Reactive power
  • Current
  • Voltage
  • Frequency

Inputs and outputs

The B 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 B 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.
