Review on GAEYAELE GRV8-01 Single Phase Voltage Relay Adjustable Over/Under Voltage Protection Monitor With LED Display (AD48) by Chris Ledet
GRV8 -02 Voltage sensor
like: small, din mount fit anywhere. I got the over and under voltage option due to price less than one with just under voltage only. do not need the over voltage on this application but it there to useddis-like: the potentiometer pointer is hard to see where the set to, number too small. no option to calibrate to supply voltage.
- works well
- Lack of versatility: This relay only monitors voltage levels, which limits its use for other electrical measurements. It cannot be used to monitor other aspects, such as current or temperature
