Voltage control relay F&F CP-721-1 1 pc. Review

Pros: The voltage control relay fully lived up to expectations. The device is easy to install. The cost is acceptable. Wide range of boundary stresses. Cons below: It is difficult to understand the setting, but this is not important, since you set the range once when connecting.

Probably not the most beautiful relay available on the market, as RBUZ bypasses it in terms of aesthetics. But it is necessary not for beauty, but for business. The relay works flawlessly.

the relay periodically turns off due to overvoltage. history always saves 276 volts. it cannot be that power surges consistently gave 276 volts. enumeration of voltage and time settings does not help. off about once a week or two. Through technical support I was able to replace the relay with another one. he has the same problem. It's been out twice in a week

It showed itself after installation on the very first day, it worked to increase the voltage at standard settings (out of habit, I didn’t immediately understand what happened). Satisfied. ps more on the channel "Electrician's Notes"

Never, ever buy this relay. Not only does it not work with shutdown delays, but also the technical support is disgusting, there is a boor in the engineering service who confidently declares that their device is perfect, and all the problems are in the rest of the electrics.
