The EM445 single phase meter is compact and easily installed. It is ideal for most domestic installations, including landlord rentals, solar panels, studios, during renovations and basic monitoring of energy. The meter provides measurement of active (kWh) energy on an easy to read LCD display.

The LED on the front of the meter flashes red when energy is being used. The faster the LED flashes the more energy is being used.

5 + 2 LCD display cannot be reset to zero and has a reading accuracy of 1/100 kWh.

To enable the connection of energy management systems, this meter has an electronic pulsed output.
The pulsed output connects onto two auxiliary terminals in the main terminal block and is polarity dependant with a passive transistor output which requires an external source for operation.

For this external voltage source, the voltage (Ui) should is 5-27V DC, and the maximum input current (Imax) is 27mA DC. To connect the impulse output, connect 5-27V DC to connector 20 (anode), and the signal wire (S) to connector 21 (cathode).

The meter comes with a full 12 month warranty
