connected to heat pump, works perfectly. Cut a hole in my circuit board to mount the display. I put both lead wires through the current transformers, one forward and the other backward. and the power supply connected to one side and neutral so that the power is read correctly, kW and kWh, the current shown on the display must be divided by 2 and the voltage multiplied by 2. This can be solved by connecting a precise 10 ohm shunt resistor through CT, but that's not a problem, I want to see kWh so I can compare electricity costs with my backup propane. I will get two more for the water heater and well pump, I am retired. Things.
