Purpose

WB-MAP12 is a multichannel electricity meter(meter of electrical network parameters) designed for energy management and power quality monitoring. The WB-MAP12 meter is ideal for process electricity metering in apartment buildings and office buildings, for consumer monitoring in data centers and smart offices.

The use of external plug-in current transformers allows system installation without disconnecting the energy consumers.


For active energy meter provides accuracy class 0.5 S. For reactive energy - accuracy class is 1.

Counter power supply

The WB-MAP12(H) counter can be powered from any of the connected phases. For data exchange via Modbus to the controller, you must also apply power to the connector the front end. It is possible to power the meter only from the interface part. In this case, the AC parameters are not measured (the voltage across all channels will be displayed as 0 V), but the current values obtained from the current transformers will be measured correctly.

The stored energy values are stored when the meter is powered off.

Operation at voltage failures and interruptions

Measurement of energy stops when the voltage is less than 180 volts (the failure or interruption of the voltage), the threshold is set in one of the Modbus-registers of the meter.

Data exchange

At the physical level, the module is connected via RS-485 interface. Modbus RTU Protocol is used to control the meter. In Wirenboard Devices, Modbus data is transmitted over RS-485 communication lines. See the Modbus Protocol page for details. Modbus-the address of the counter is set at the factory and marked on the label. The address can be changed programmatically. Details refer to the Modbus control.

Status lights indication

Led status lights

The counter has 5 led indicators:

  • S — the green status indicator flashes when communicating via Modbus
  • CF1...CF4 — red indicators of total energy consumption for each of the three-phase channels (only active energy is taken into account). Flashing indicators refers to consumption electricity: 1000 pulses correspond to 1 kWh (in firmware to v.2,1 - 3200 pulses per 1 kWh).

When you add a WB-MAP12 device, you can choose from several device templates:


Template Model and purpose
WB-MAP12H The basic pattern for measurement of the coefficients of the harmonics of current and voltage
WB-MAP12H (basic) Simplified template for models without measuring current and voltage harmonics (no values of AN, Ifund, N, NN, RN, NP, Pfund, Pharm, S, THD I, THD U, Total AN, Total N, Total Pfund, Total Pharm, Total RN, Total RP, Total S, Total SV, Ufund -- see names on page with list of measured parameters, link above).
WB-MAP12H (+ harmonics) Advanced pattern models with the measurement of the coefficients of the harmonics of current and voltage (up to 15 harmonic current and up to 7 harmonics voltage)
WB-MAP12H (+ all harmonics) Complete template for models measuring current and voltage harmonics (up to 42 current and voltage harmonics)
WB-MAP12H (basic div2) Simplified template for models without measuring the coefficients of the harmonics of current and voltage inputs, designed for currents > 65 A
WB-MAP12E Template for models that support the measurement of subsidence of voltage and current (model in development)

Description of Modbus registers

The meter supports a large number of Modbus registers that store the values of measured and calculated values, as well as counter control registers.

A table of registers describing the measured values can be found on the page Power_Meter_Measuring_Registers.

Table of control registers is given in the page Power Meter WB-MAP12H Control Registers.
