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.

The 12V DC voltage regulator is very accurate after I did a power supply comparison. I just wish the current rating could be higher than 10A.

Pedi varias piezas y el monitor de fase no sirve y pensaba que el venderor me la iba a remplazar, y reenviarle la pieza me sale 46 dolares, no compren eso no sirve...

Mine it's damaged after 1day of use with 10A, that's not good. I bought another one for install with a relay, because it does work with monitoring but NOT with the current they said.

Received the A220 model. These units are fantastic and customer support is awesome. I bought a GRT8 time delay unit also, these are great value for the money. The D12 makes a great UV cutoff for a LiFePO4 12v battery. I use the AD240 model in an automatic capacitor precharge/bleed circuit. These products are really superb!

Works perfectly like it says. I’ve had it in use for about 3 months now with no problems.

Product failed after few hours of use. Started blinking and refused to output power.

Just received and done some preliminary tests - so far looks like it will do what we need (monitoring Battery Bank on Solar System / shut down inverters if Over / Under Voltage on Batteries). Time will tell once installed - giving 5 stars based upon initial testing - will update if things change.
