Description
Dual-direction three-phase meter. Maximum current 3x80A, standby loss only 0.5 watts per path. DIN-EN 60715 TH35 DIN rail mounting device. 4 divisions = 70mm wide, 58mm deep. Accuracy class B (1%). With S0 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 a maximum of 0.5 watts of 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 80 A. Starting current is 4O mA. The N-connection must be available. The energy reference and the supply of energy are stored non-volatile 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. The power reference and the power delivery are indicated with a flashing bar on the display 100 times per kWh. 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: If the external conductor is missing, the corresponding external conductor is displayed.
