Three-phase static electricity meters AMT B3x-OA4SET are determined for direct measurement of active energy with measured consumption displaying on LCD. They are manufactured in single-rate and double-rate versions with external switching of rates.

Three-phase static electricity meters AMT B3x-FA4SET are determined for measurement of active energy, instantaneous active power for consumption and supply, voltage, current and power factor in 3-phase 4-wires network in direct connection. They enable measurement of energy in rates controlled by internal clock (up to 4 rates) or externally controlled in two rates. The measured values stored into special registers according to the OBIS codes are displayed on LCD in cyclic or step mode. The data are stored in non-volatile memory during power outage, which can be viewed on the LCD. The electricity meters can be parametrized and readout by using optical probe AMOS type and software supplied by the manufacturer. The testing pulses proportional to the consumed energy are signalling by a red LED. The meters can be produced in version with measurement in summary mode (measurement „using an unidirectional mechanical register“) or with measurement in separation mode (measurement of “consumption – supply”).

Three-phase multifunctional static electricity meters AMT B2x-Fx4TxIx are determined for measurement of active, reactive and apparent electric energy, instantaneous active, reactive and apparent power for consumption and supply, maximum demand for active, reactive and apparent energy, voltage, current and power factor in 3-phase 4-wires networks in direct and semidirect connection. They enable measurement of energy in rates controlled by internal clock (up to 4 rates) or externally controlled in two rates. The measured values stored into special registers according to the OBIS codes are displayed on LCD in cyclic or step mode. The electricity meters can be parametrized and readout by using optical probe AMOS type and software supplied by the manufacturer. The test pulses are indicated by red LEDs, they are proportional to the active and reactive consumed energy. Electricity meters can be produced in version with summary measuring mode (unidirectional register) or in version with separate mode (consumption - supply).

Single-phase static electricity meters AMS B3x-Fx are determined for measurement of active energy, instantaneous active power, voltage, current and power factor in single-phase 2-wire network in direct connection. They enable record of the selected energy registers contents (total and rate) for billing period (max. 15 records). The electricity meters are equipped with internal real time clock (RTC) which is used for switching of maximum four rates. It is also possible to record events, such as, for example, voltage outage, terminal block cover removal, meter cover removal and magnetic field influence.

Single-phase static electricity meters AMS B2x-Fx are determined for measurement of active, reactive and apparent energy, instantaneous active, reactive and apparent maximum demand, voltage, current and P.F. in 2-wire networks in direct connection. They enable measurement of energy in rates controlled by internal clock (up to 4 rates) or externally controlled in two rates. The measured values stored in registers according to the OBIS codes are displayed on LCD in cyclic or stepping mode. The electricity meters can be parametrized and readout by using optical probe AMOS type and software supplied by the manufacturer. The testing pulses are signalling by a red LEDs separately for active and reactive energy. The meters can be produced in version with measurement in summary mode (unidirectional register) or with measurement in separation mode (consumption – supply).

The local unit OPS is the microcomputer unit for error evaluation of the tested electricity meter.
