The device for making indications in metric units (kWh) is used for direct measurement of active power in a single-phase system and registration of the consumed electricity with the possibility of remote reading of the registers of a group of indicators, through a wired network of the RS485 standard. Protocol: Modbus-RTU type and 4 independent tariffs (the user can set different times via RS485 port). A special electronic system, under the influence of the flowing current and the applied voltage, generates impulses in an amount proportional to the electrical energy consumed. The power consumption in phase is indicated by the flashing of the LED. The number of pulses is converted into energy consumed, and its value is indicated by the LCD display (5+1). Lithium battery for real clock, the accuracy of which is 0.5 sec/day. Power supply: 230V~, 50Hz, base current: 5A, max. current: 100A, min. current: 0.25A, pulse frequency: 1000 imp/kWh, accuracy class B, housing with a width of one module, mounting on DIN rail TH-35 mm. Energy measurement is performed in accordance with the EN50470-1:2006, EN50470-3:2006 standards of the MID Directive 2014/32/EU.
