Eltako DSZ14DRSZ-3x80A MID

Only calibrated meters are approved for electricity billing according to Section 25 of the German Calibration Act. Non-compliance is considered an administrative offense under Section 19. RS485 bus two-way three-phase meter. Maximum current 3x80A, standby loss only 0.8 watts on L1 and 0.5 watts each on L2 and L3. Rail-mounted device for installation on DIN-EN 60715 TH35 mounting rails in installation cabinets with protection class IP51. 4 division units = 70 mm wide, 58 mm deep. Accuracy class B (1%). With RS485 interface. The directly measuring three-phase meter measures active energy based on the currents flowing between the inputs and outputs. The self-consumption of only 0.8 watts or 0.5 watts active power per path is not measured and not displayed. The active energy is added depending on the sign. Positive power in the meter indicates energy consumption, while negative power indicates energy delivery. Energy measurement is net. If energy consumption (P positive) is greater than energy delivery (P negative), the meter reading increases to the right. If energy delivery is greater than energy consumption, the meter reading increases to the left. Energy consumption is indicated with a right arrow and energy delivery with a left arrow above the active bar on the display. 1, 2, or 3 external conductors with currents up to 80 A can be connected. The starting current is 40 mA. Connections L1 and N must be present. Connection via an FBA14 to the Eltako RS485 bus with a 2-wire shielded bus cable. The meter reading and instantaneous power are transmitted to the bus and also sent via the FAM14 into the radio network. It is necessary for the radio antenna module FAM14 to assign a device address as described in the operating manual.
