Device for measuring in metric units (kWh), it is used for the direct measurement of active power in a three-phase system and for the registration of consumed electric energy with the option of remote reading of the indicator group registers via a wired RS485 standard network. Protocol: Modbus-RTU type and 4 independent tariffs (the user can set different times via the RS485 port). Equipped with an optical IR port ? works with the optical head OR-WE-518. A special electronic circuit under the influence of the flowing current and the applied voltage generates pulses in a number proportional to the consumed electric energy. Energy consumption in the phase is signaled by the blinking of an LED. The number of pulses is converted into consumed energy, and its value is displayed on an LCD (6+2). Power supply: 230V~, 50Hz, base current: 5A, max. current: 80A, min. current: 0.25A, pulse frequency: 1000 imp/kWh, accuracy class B, housing width of three modules, mounting on DIN TH-35 mm. Energy measurement is performed according to the standards EN50470-1:2006, EN50470-3:2006 MID Directive 2014/32/EU.
