RS485 bus radio three-phase meter. Maximum current 3x80A, standby loss only 0.8 watts at L1 and 0.5 W each at L2 and L3. Modular device for mounting on DIN-EN 60715 TH35 mounting rail in installation cabinets with protection class IP51. 4 division units = 70mm wide, 58mm deep. Accuracy class B (1%). With RS485 interface. The direct measuring three-phase meter measures the active energy based on the currents flowing between the inputs and outputs. The self-consumption of only 0.8 watts or 0.5W active power per path is not measured and not displayed. 1, 2 or 3 external conductors with currents up to 80A can be connected. The starting current is 4OmA. The L1 and N connections must be present. Connection via an FBA14 to the Eltako RS485 bus with a 2-wire shielded bus cable (e.g. telephone line). The meter reading and the current power are transferred to the bus - e.g. for forwarding to an external computer or Professional Smart Home Controller - and also sent to the radio network via the FAM14. This requires that a device address is assigned to the FAM14 radio antenna module, as described in the operating instructions. The 7-segment LC display can be read twice within two weeks even without a power supply. The power consumption is shown by an LED next to the display that flashes 1000 times per kWh. Can also be used as a 2-tariff meter as standard: Applying 230V to terminals E1/E2 switches to a second tariff. To the right of the display are the MODE and SELECT buttons, which are used to scroll through the menu according to the operating instructions. First, the background lighting switches on. The total active energy per tariff, the active energy of the resettable memory RS1 or RS2 as well as the instantaneous values of power, voltage and current per phase conductor can then be displayed. Error message (false): If the outer conductor is missing or the current direction is incorrect, false and the corresponding outer conductor is shown in the display.
