The counter MERCURY 231 AT-01 I is designed to measure electricalmachines (A+), as well as the organization multirate in three-phase three-wire or four-wire circuits AC, with direct connection to the voltage and current to the circuits of the generator and load. Does mercury 231 at rated voltage 3x230/400 V and power current 5 - 60 A. the Model corresponds to accuracy class 1 has a built-in interfaces: pulse output and IrDA.

The purpose counters

Three-phase meters type MERCURY 231 AT-01. Designed to measure active electric energy in three-phase three-wire and four-wire alternating current circuits. Apply for organization of multirate.

Each model multi-tariff meter type mercury AT 231 has a pulse output and IrDA interface (infrared port).

Electrical meters energy MERCURY 231 at-01 I can be used independently or in the automated system of data collection on energy consumption.

Designed to work in a closed room. Operating conditions belong to the group of 4 GOST 22261.

   The device and principle of operation

As current sensors in the counter-type Mercury 231 uses current transformers. As voltage sensors are resistive dividers. The signals from the current sensors and the voltage received at the inputs of analog-to-digital Converter (ADC) the microcontroller (MC). After digitization of the signals of the ADC is further mathematical processing of their codes in MK, which is the value power. Integrating the received power values over time gives information on the amount of energy consumed. MK controls the output of information on LCD, processes, and responds to requests for built-in interfaces counter.

MK sets the current tariff zone depending on the commands received by the interface or from the timer generates a pulse telemetry, conducts electricity metering in included in the tariff. The counter circuit includes non-volatile memory, in which data is stored on reactive energy for each tariff, calibration value measurements and programmable settings for the desired operation of the device. MK synchronized with a quartz resonator, operating at a frequency of 32768 Hz.

Galvanic isolation internal and external circuits of the meter is made on the optocoupler the led-phototransistor. Through isolation signals are telemetry output (pulse output device).
