Mobile AC meter with CEE plug and CEE socket. Equipped with an additional personal protection intermediate switch PRCD 30mA. Suitable for indoor and outdoor use. Maximum current 16A. Standby loss is only 0.4 watts. Housing dimensions are 110 x 70 x 35 mm, connection cable is 1.5 m (including plug and socket). Accuracy class B (1%). This mobile AC meter measures active energy based on the current flowing between the input and output. The self-consumption of only a maximum of 0.4 watts of active power is not measured or displayed. Every 30 seconds, the display switches for 5 seconds from the accumulated active energy in kWh to the instantaneous consumption in watts. The starting current is 20 mA. The display can only be read when powered. However, the consumption is stored non-volatile and will be immediately displayed again after a power failure. The digital display has 7 digits. Up to 99999.99 kWh, two decimal places are shown; from 100000.0 kWh, only one decimal place is displayed. Power consumption is indicated by a blinking LED that flashes 2000 times per kWh. The personal protection intermediate switch PRCD detects fault currents that may occur when touching a faulty electrical device and interrupts the current quickly enough to prevent life-threatening accidents. It also has a undervoltage release that shuts off in case of power failure. With function indicator and test circuit.
