ELTAKO Converter Three-Phase Meter, MID 2019 – 28305015

Current transformer three-phase meter with settable transformer ratio and MID. Maximum current 3x5A, standby loss only 0.5 Watt per path. Series installation device for mounting on DIN-EN 60715 TH35 mounting rail. 4 module units = 70mm wide, 58mm deep. Accuracy class B (1%). With S0 interface. This three-phase meter measures active energy based on the currents flowing through the current transformers. The self-consumption of only a maximum of 0.5 Watt active power per path is not measured and not displayed. 1, 2 or 3 current transformers with secondary currents up to 5A can be connected. The starting current is 10mA. The N-connection must be present. The 7-segment LC display can be read twice within two weeks even without power supply. The power consumption is indicated by a bar flashing 10 times per kWh in the display. To the right of the display are the MODE and SELECT buttons, which are used to navigate the menu according to the operating instructions. First, the backlight switches on. Afterwards, the total active energy, the active energy of the resettable memory as well as the instantaneous values of power, voltage and current per phase conductor can be displayed. In addition, the current transformer ratio can be set. Ex-factory, it is set to 5:5 and locked with a jumper across the terminals marked 'JUMPER'. The current transformer ratio is adjusted to the installed transformer by removing the jumper and re-setting it according to the operating instructions. Afterwards, it is locked again with the jumper. The following current transformer ratios can be set: 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): In case of a missing phase conductor or wrong current direction, "false" and the corresponding phase conductor are displayed. Attention! Before working on the current transformers, disconnect the voltage paths of the meter.
