Specifications: Type: Three Phase Backlight: No Other Features: IR Optical Port Base Current (lb): 5A Protection Grade (IP): 51 Maximum Current (lmax): 80A Minimum Current (lmin): 0. 25A Pulse frequency: 1000imp/kWh Measurement accuracy class: B Pulse output: yes Multitariff: yes Number of modules: 4.50 Display - number of digits: 6 + 2 MID compliance (2014/32/EU): yes Communication protocol: Modbus Dimensions - depth: 66mm Dimensions - width: 76mm Dimensions - height: 100mm Ports: RS485 Supply voltage: 3 x 230V/400V~, 50/60Hz The device for making indications in metric units (kWh) is used for direct measurement of active power in a three-phase system and registration of consumed electricity with the possibility of remote reading of indicator group registers, via a wired RS485 network. Protocol: Modbus-RTU type and 4 independent tariffs (the user can set different times via the RS485 port). Equipped with an IR optical port – works with the OR-WE-518 optical head. A special electronic system, under the influence of the flowing current and the applied voltage, generates pulses in an amount proportional to the consumed electricity. The energy consumption in the phase is signaled by flashing an LED. The number of pulses is converted into the consumed energy , and its value is indicated by the LCD display (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 with a width of three modules, mounting on a DIN rail TH-35 mm. The meter is bidirectional, i.e. it also counts the energy produced by the consumer. Energy measurement is performed in accordance with the standards EN50470-1:2006, EN50470-3:2006 of the MID Directive 2014/32/EU. **
