Wireless AC meter, maximum current 65A. Standby loss only 0.5 watts. Modular device for mounting on DIN-EN 60715 TH35 rail. 1 division unit = 18mm wide, 58mm deep. This AC meter measures the active energy based on the current flowing between the input and the output and sends the instantaneous power and the meter reading to the Eltako wireless network. Accuracy class B (1%). Evaluation and smart connection via a smart home controller. The self-consumption of only a maximum of 0.5 watts of active power is not measured. Like all meters without an MID declaration of conformity in Europe, not approved for monetary electricity billing. 1 outer conductor with a current of up to 65A can be connected. If the expected load is more than 50%, a ventilation distance of 1/2 division unit must be maintained from devices mounted next to it. Use the DS12 spacer if necessary. The starting current is 40mA. The consumption is stored in a non-volatile memory and is immediately available after a power failure. Radio telegrams: A telegram is sent within 60 seconds if the power has changed by at least 10 percent. A change in the meter reading is sent immediately. A total telegram with the meter reading and power is sent every 10 minutes. When the supply voltage is switched on, a learning telegram is automatically sent so that the associated energy consumption display can be learned. If the L input and L output were swapped when connecting, an HT/NT switchover telegram is sent every 20 seconds to indicate the connection error.
