amiciSmart Over/Under Voltage, Over Current/Load Protection with Digital Energy Meter Din Rail Mounted (63A, 230V)

very good device

I got this product for my inverter AC since my ac functions at 100-290 volts, I only needed a device that would cutoff above and below these levels and not a compte stabilizer. Not to mention, wall mounting a stabilizer looks ugly af.This relay has undervolt, overvolt and overcurrent protection with startup delay timer as well. Every value is fully adjustable. The setup is easy IF you know what which letters stand for overcurrent, overvolt etc etc. Amicikart has included a manual of sorts but I found a YouTube video which explains where to enter what value. Search for "voltage protection relay setup" on YouTube.I setup undervolt to 170 and overvolt to 270 for my AC (Even though my AC supports 100-290, running it at too low of a voltage increases the current by a lot, thereby potentially stressing the components).My area has a voltage between 200-250 volts 95% of the time but there were certain times at night when the voltage would suddenly drop to below 170 and this device cut off the power to my AC. An overvoltage situation also happened once and this device worked as it should have.I'd also like to point out that the voltage and current display is very accurate (+-2volts) so full marks there as well. This was crosschecked with a smartplug that I have as well as a multimeter.Make sure you don't flip the polarity while installation. Live should go L and neutral should go to N. Also pay attention to which side is input and which side is output- this should not be revered either. An arrow pointing towards the terminals is marked and that is the input, the arrow which points away from the terminal marks the output terminal.All in all I'm very happy with my purchase. As I only needed a cutoff relay and not a stabilizer this product served me well. How long it works and how good Amicikart support is, is yet to be seen. I will update my review if anything new pops up which is worth mentioning

The product is good to safeguard expensive electronic gadgets I am using it to regulate voltage for water motor and pressure motor. Although is it not a voltage stabilizer only regulator it does what it says. After around 9 months the product suddenly stopped working but when contacted the service centre they arranged a pickup and replaced the product without any hassel. So I would recommend this product to anyone wanting to safeguard their home appliances without buying a stabilizer.

Accuracy. parfectPerformance. goodDisplay. Working parfectEase of use. YesOverall good product for every electrical'electronics device protectOver voltage and under voltage protection is awesome 👍

Even though the product is small, its function is amazing and care from manufacturers about the buyer was surprised me lot.

Bought this from Amazon to fit on incoming supply for EV charging box. It was very easy to install and setup. Basic reading of the manual is all we need and the functions it provides is very useful and great for Electronic device connected to the line. It protects my EV charging box and vehicle charging with proper Input supply. Their service is also quite good and they help instantly over phone for troubleshooting.Thanks
