DEWIN Transfer Switch
I mounted it in a self-built UPS type system. It works well, switching occurs quickly. I hope it lasts.

Voltage tolerance to tight
Does not work on uk voltage as the average uk voltage is 245vac

Not suitable for UK grid voltage
This feels like a well built product, but this product is not designed for UK grid voltage. Max allowed UK grid voltage is 253.6V. At my property the grid voltage is usually 251V. The manual that comes with the product says over voltage is 270V, then voltage to restore is 250V +-5V.When connected, the LED for grid voltage flashes to indicate it is "out of spec". My backup power is 230V, when that is energised it switches over without issue, but it will not switch back to grid power because it is "out of spec".This product will work in some locations in the UK, but how many people know their local grid voltage ?This product is useless to me and I will be returning.

Transfer time very debatable.
No way in hell that's transfer time is 50ms or less. At least not from main source to secondary.
