Eltako 28380512 DSZ15DM-3x80A MID calibrated M-Bus three-phase meter

Only calibrated meters are permitted for electricity billing according to paragraph 25 of the German Calibration Act. Failure to comply is an administrative offence according to paragraph 19. M-Bus three-phase meter. Maximum current 3x80A, standby loss only 0.5 watts per path. Series-mounted device for mounting on DIN-EN 60715 TH35 mounting rail. 4 division units = 70mm wide, 58mm deep. Accuracy class B (1%). With M-Bus interface. The direct-measuring three-phase meter measures the active energy based on the currents flowing between the inputs and outputs. The internal consumption of only a maximum of 0.5 watts of active power per path is not measured and is not displayed. 1, 2 or 3 external conductors with currents of up to 80A can be connected. The starting current is 4OmA. The N connection must be present. The 7-segment LC display can be read twice within two weeks even without a power supply. The power consumption is displayed with an LED 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. Then the total active energy per tariff, the active energy of the resettable memory RS1 or RS2 and the instantaneous values of power, voltage and current per outer conductor can be displayed. Error message (false): If an outer conductor is missing or the current direction is incorrect, false and the corresponding outer conductor are shown in the display. M-Bus data transfer: When reading out, all values are transmitted in one telegram. The following telegrams are supported: Initialization: SNDNKE, response: ACK, read meter: REQUD2, response: RSPUD, change primary address: SNDUD, response: ACK, reset RS1: SNDUD, response: ACK, slave selection for the secondary address, response: ACK. The device does not respond to unknown queries. The transmission rate is automatically detected. The device has a voltage monitor. In the event of a voltage loss, all registers are saved in the EEPROM. Changing the M-Bus primary address: To change the M-Bus primary address, hold down SELECT for 3 seconds. In the following menu, MODE increases the address by 10, SELECT increases it by 1. When the desired primary address is set, wait until the main menu appears again. Secondary address: Using the secondary address, it is possible to communicate with the energy meter in accordance with the EN13757 standard. Wild cards can be used.
