Works Great , used this on my Sailboat Instrument Panel to show when AC Voltage On ! Better than I expected !!!

These worked great, accurate enough for anything I would ever do. I Read the warning against using with vfd's but tried it anyways and even at low voltage/ speed they immediately all blew resistors. Not sure why, but they worked fine until then. For the cost you can't get anything else that will monitor 3 phases and mount cleanly in a small enclosure

I added these to a MEP-803a, military surplus generator. My voltage and power guages had failed, and these seem to be adequate replacements for metering.I have voltage/freq/current meters further down the output, and they measure very close, within a few volts and less than 1hz difference.

While a Fluke and two other meters read 119.5 VAC, all three of these panel meters displayed 115. They draw 22 mA

My ONLY problem had to do with me finding a blue version and discovering that its connectors to the current donut were incompatible - which was annoying since I had already partially wired it.So I guess I'd say "be careful if you buy something that looks identical to verify the connectors are compatible if you plan on mixing and matching."Has been in constant use for probably a month with no issues. The casing is plastic, so you probably don't want to put it in situations where it deals with lots of movements, but in my case, I only read it - I don't touch it.And for that, it's a great solution. Very happy.AS EXPECTED

Using these to monitor generator emergency power. Hertz’s in right on and the voltage is 0.3-0.4 high compared to my Fluke meter.

Two of the units worked great..the third was dim and had erroneous readings. Seller not really responsive. Overall I’m satisfied. Used in panel to display generator load.

Unit work well monitoring 3 phase power on electric heater.
