I tested the PowerMeter with a 30W-Driverless Power-Led.It accurately displayed power,current and voltage.The Powerfactor value seems to be ok too. (couldn't compare the displayed value to a professionel powerfactor meter as I don't have one...) Even though the PowerMeter was a 100A-version the small current of the 30W-Led was nicely displayed. The build quality was ok and I also liked the clear display.I took it apart to see what it looked like inside.Instead of a simple capacitor powersupply for the module itself they now use an integrated switching circuit which should be far more efficient and producing less heat.Like it ! The module obviously uses a 100 Ohm SMD-resistor (R15) as a fuse.in case of a major malfunction.I am not sure if this SMD-resistor is burnproofed and because of this uncertainty I am giving the product "only" 4 stars. All in all it's a nice product - good value for money.Vollständige Rezension lesen
