DSZ14DRSZ-3x80A MID Eltako RS485 2-way 3-phase meter
Only calibrated meters are permitted for electricity billing in accordance with paragraph 25 of the German Calibration Act. Non-compliance is an irregularity in accordance with paragraph 19. RS485-bus two-way three-phase meter. Maximum current 3x80A, standby-loss only 0.8 Watt at L1 and each 0.5 W at L2 and L3. DIN-EN 60715 TH35 DIN rail mounting device in installation cabinets with protection class IP51. 4 divisions = 70mm wide, 58mm deep. Accuracy class B (1%). With RS485 interface. The directly measuring three-phase meter measures the active energy by means of the currents flowing between the inputs and outputs. The intrinsic consumption of only 0.8 watt or 0.5W active power per path is not measured and not displayed. The active energy is added depending on the sign. Positive power in the counter means energy reference, a negative power means energy supply. The energy measurement is performed by balancing. If the energy reference (P positive) is greater than the power supply (P negative), the counter reading T arrow on the right is increased. If the power supply is greater than the energy reference, the counter reading T arrow on the left is increased. Energy reference is indicated with a right arrow and power supply is indicated with a left arrow above the active bar in the display. 1, 2 or 3 external conductor can be connected with currents up to 80A. The starting current is 4OmA. Connections L1 and N must be present. Connection via an FBA14 to the Eltako-RS485 bus with a 2-wire shielded bus cable (e.g. Telephone cable). The meter reading and the instantaneous power are transferred to the bus â for example for transmission to an external computer or GFVS 4.0 software â and also sent to the radio network via the FAM14. This requires that the FAM14 wireless antenna module assigns a device address as described in the operating instructions. The 7-segment LC-display can also be read twice within two weeks without power supply. The power reference is indicated by a LED flashing 1000 times per kWh next to the display. The MODE and SELECT buttons are used to the right of the display to scroll through the menu according to the operating instructions. First the backlighting is switched on. After this, the total active energy per reference and delivery, the active energy of the resettable memory reference and delivery as well as the instantaneous values of power, voltage and current per external conductor can be displayed. Error message (false): If the external conductor is missing, false and the corresponding external conductor is displayed.This text is machine translated.
