ELTAKO Bi-directional Three-Phase Meter, MID certified - 28480315

Bi-directional three-phase meter. Maximum current 3x80A, standby loss only 0.5 watts per phase. Modular device for mounting on DIN-EN 60715 TH35 top-hat rail. 4 division units = 70mm wide, 58mm deep. Accuracy class B (1%). With S0 interface. The direct-measuring three-phase meter measures active energy based on the currents flowing between the inputs and outputs. The self-consumption of only a maximum of 0.5 watts of active power per path is not measured or displayed. The active energy is added depending on the sign. Positive power in the meter means energy consumption, negative power means energy delivery. Energy measurement is balancing. If energy consumption (P positive) is greater than energy delivery (P negative), the meter reading T arrow right is increased. If energy delivery is greater than energy consumption, the meter reading T arrow left is increased. Energy consumption is indicated by a right arrow and energy delivery by a left arrow above the active bar in the display. 1, 2 or 3 external conductors with currents up to 80A can be connected. The starting current is 4OmA. The N-connection must be present. Energy consumption and energy delivery are stored non-volatily and are immediately displayed again after a power failure. The 7-segment LC display can also be read twice within two weeks without power supply. Power consumption and power delivery are indicated by a bar in the display that flashes 100 times per kWh. 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 consumption and delivery, the active energy of the resettable memories for consumption and delivery, as well as the instantaneous values for power, voltage and current per external conductor can be displayed. Error message: If an external conductor is missing, the corresponding external conductor is displayed.
