Eltako 28305015 DSZ15WD-3x5A three-phase meter 3x5A calibrated content_copy

Transformer-based three-phase meter with adjustable transformer ratio and MID. Maximum current 3x5A, standby loss only 0.5 watts per path. Modular device for mounting on DIN-EN 60715 TH35 rail. 4 division units = 70mm wide, 58mm deep. Accuracy class B (1%). With S0 interface. This three-phase meter measures the active energy based on the currents flowing through the transformers. The internal consumption of only a maximum of 0.5 watts of active power per path is not measured and not displayed. 1, 2 or 3 transformers with secondary currents of up to 5A can be connected. The starting current is 10mA. The N connection must be present. The 7-segment LC display can also be read twice within two weeks without a power supply. The power consumption is shown in the display with a bar that flashes 10 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 background lighting switches on. Then the total active energy, the active energy of the resettable memory and the instantaneous values of power, voltage and current for each outer conductor can be displayed. The transformer ratio can also be set. It is set to 5:5 at the factory and locked with a jumper across the connection terminals marked JUMPER. The transformer ratio is adapted to the installed transformer by removing the jumper and resetting it according to the operating instructions. It is then locked again with the jumper. The transformer ratios that can be set are 5:5, 50:5, 100:5, 150:5, 200:5, 250:5, 300:5, 400:5, 500:5, 600:5, 750:5, 1000:5, 1250:5 and 1500:5. Error message (false): If the phase conductor is missing or the current direction is incorrect, false and the corresponding phase conductor are shown on the display. Attention! Disconnect the meter's voltage paths before working on the current transformers.
