Multi-rate microprocessor-based three-phase energy meter ALPHA is designed for accounting of active and reactive power in AC circuits, as well as for use in automated control systems and electricity metering for the transmission of measured or calculated parameters dispatch center control, registration and distribution of electrical energy. The measuring principle is laid down in the counter based on analog-to-digital conversion values of voltage and current with the subsequent calculation of energy and power. The alpha meter consists of the measuring sensors of voltage and current, the main circuit Board with a microprocessor circuit for measuring high-speed microcontroller. Measured values and other requested data is displayed on the counter display made on liquid crystals. Measurement of current and voltage of power circuits is carried out using vysokoperedelnyh transformers improved design and resistive circuits voltage divider. The active power is calculated by multiplying the measured digital values of voltages and currents with the help of the very large integrated circuits (VLSI) dimensions. VLSI measurement includes a programmable digital signal processor with three built-in analog-to-digital converters (ADCS). Counter ALPHA allow for transformer or direct connection to the circuit current. When connecting to a current transformer with nominal value of 1 And the counter works in the range of currents from 1 mA to 2 A, when connected to current transformer with 5 A nominal — in the range from 5 mA to 10 A. in case of direct inclusion of the counter operates in the range of currents from 50 mA to 1 A. 50 Specially designed microcontroller maintains the accuracy over the entire operating temperature range from -40 to 60 °C With maximum and minimum loads. In the alpha meter uses a switching power supply, which allows us to provide a wide range of operating voltage from 70 to 440 V.

Relay of load control can be used as a signal in case of exceeding the power set point.

Microprocessor performance counter alpha makes it programmable, allowing you to use meter with a wide range of different functions. to access the counters for:

consumer operational services of power supply companies, maintenance services Supplying organizations with the right to Gospoverki.

To protect against unauthorized access every counter has its own password. In addition, the software has its own access codes that prevent the software to unauthorized persons.

Counters alpha there are 4 tariff zones (morning, evening, afternoon, night), weekend and holidays, 4 seasons, automatic summer and winter time.

With rock service counter alpha — 30 years with calibration every 8 years. Manufacturer warranty — 3 years.
