Eltako DSZ15DM-3x80A MID 28380512 Electricity meter (3-phase) Digital 80 A MID-approved: Yes 1 pc(s)

Only calibrated meters are approved for electricity accounting according to §25 of the German calibration law. Non-compliance is an administrative offense according to §19. M-Bus three-phase meter. Maximum current 3x80A, standby loss of only 0.5 watts per path. Series installation 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 own consumption of only a maximum of 0.5 watt 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 N connector must be present. The 7-segment LC-display can be read twice within two weeks even without power supply. The power supply is indicated by a 1000-times flashing LED per kWh. Can also be used as a 2-tariff counter as standard: When 230V is connected to terminals E1/E2, the system 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 backlight turns on. Then the total active energy per tariff, the active energy of the resettable memory RS1 or RS2 as well as the instantaneous values power, voltage and current per phase conductor can be displayed. Error message (false): If the external conductor is missing or the current direction is incorrect, false and the corresponding external conductor is shown on the display. Data transmission M-Bus: When reading out, all values are transferred in a message frame. The following message frames are supported: Initialization: SND_NKE, response: ACK, read out counter: REQ_UD2, response: RSP_UD, change primary address: SND_UD, Answer: ACK, Reset RS1: SND_UD, Answer: ACK, Slave selection for the secondary address, Answer: ACK. The device is not responding to unknown queries. The transmission rate is detected automatically. The device has voltage monitoring. In the event of a voltage loss, all registers are stored in the EEPROM. Changing the primary M-Bus address: To change the primary M-Bus address, press and hold 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 Haupt­menü 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.
