COV-32200 Voltage and Surge Protector for AIR Conditioning Inverter Mini Split 240v 220V

Works very Good in inestable power grid like I Puerto Rico 🇵🇷. This save me a lot of money protecting my inverters at 240 volts, sometimes the voltage up to 272 ac and this product save the board of the inverters.

Unit continuously cycles off unless set to maximum voltage. My power does not surge (per voltmeter) let alone for 3 seconds per spec. Not sure being required to set at maximum voltage provides much protection. I have returned this unit for a replacement to be tested. My service typically measures 238V.RE: REPLACEMENT UNITThis is ABOUT the replacement unit for the unit which not calibrated properly. It properly shuts down at the voltage read on my voltage meter. I did have to increase to 255V to avoid shutoff when the HVAC starts. This unit has been functioning properly for several days. So these units can work and a great price point. I understand the other criticisms, poor manufacturer QC.ADDITIONALLY I purchased a second (third) unit.This unit also properly shuts down (3V calibration variance) and has been working properly for a few hours. Unit was missing mounting screw (but I can handle that).

The item arrived quickly and seemed well made. I went and got a rainproff box and installed it between the disconnect and the mini split. Installing it was easy and setting it up was very easy. I powered it up and after the delay that I set expired the unit came on. We haven't had any spikes or brown outs yet so I don't know how well it works, but so far so good

I have bought like 6-7 of this and they have been working great for 2-3 years so far.

Best investment to protect split a/c. Purchased after my first split ac burnt out after a power surge and cost me well $1200 with install then had to replace ac for another $1200 for a total of $2400. This $20 device saved me this time around so I purchased 4 more as backups. Living on an island we get a lot of brownouts/surges spikes whatever. In the photos it blew out the capacitors on the device rather than the a/c fair enough replaced in 5 mins for $20 saved $1200 that is all excellent product. Please note it does not blow out the capacitors like this all the time, it simply shuts off and clicks back 3 mins after the voltage is normal. BUY now but leave some for me.

Poor quality, it does not work

I used it for my two 12K BTU inverter consoles.

In 2023 there is no excuse not to at least have 2 language instructions, its a simple product but still, spanish instructions are useless to meAs far as actual product i just got it so no idea how well it works
