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. Maximum current 65A, standby loss only 0.4 watts. Series installation device for mounting on DIN-EN 60715 TH35 mounting rail. 1 division unit = 18mm wide, 58mm deep. Accuracy class B (1%). With S0 interface. This AC meter measures the active energy based on the current flowing between the input and the output. The own consumption of only a maximum of 0.4 watt active power is not measured and not displayed. 1 external conductor can be connected with a current of up to 65A. The starting current is 4OmA. With an expected load of more than 50%, a ventilation distance of 1/2 division unit to adjacent Âmontierten devices must be observed. If necessary, use spacer DS12. Two N terminals for secure cross-wiring of several counters. The 7-segment LC-display can be read twice within two weeks even without power supply. To do this, press the button. Below the display there is a button with which you can scroll in the menu according to the operating instructions. First, the backlight turns on. The total active energy, the active energy of the resettable memory as well as the instantaneous values active power, voltage and current can then be displayed. The power consumption is indicated by a 1000 times per kWh flashing bar in the display. Error message: If there is a connection error, the backlight of the display flashes.This text is machine translated.
