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

Working good

Excellent product Showing current voltage and power unit consumption in unit .

We often used mcbs in home for protection but it gives protection related to abrupt current variation. But we need to protect our home appliances from high or low voltage too. Our refrigerator and few other gadgets were damaged in this winter season due to high voltage in our apartment during winter. This device is very helpful which protects from high, low voltage and current. It has voltage and current and power indicator too.we can adjust protection level in it. It trips the power when the current and voltage is at undesired level and automatically reinstate it when it is at safe level. Take help of qualified electrician for first installation. Good innovative product.

Today, I completed the setup of my ACDB box. Since there wasn't enough space in the original ACDB box, I removed the changeover switch and installed it—along with a 2-pole MCB—in a separate box that I built myself; I then installed this device into the ACDB box. It would be fine if this device works perfectly now.
