DEWIN Transfer Switch, Automatic Transfer Switch G2R 63A DIN Rail ATS Dual Po...

I bougth this product from UK and i want just to let you know the This device IS WORKING in the UK electric network , at my place the voltage is 230v and the device worked just fine without any problems , the quality of the product looking from outside is decent , (rated for 65A but i do not to switch more than 30A, as all the china specs has to be 50% derated in general. In long run i don't know how it will work , and i will come back to complete this review if the product will not last as expected. (at least 12months) . Until then all i can say is that i'm happy with the product , decent product at a decent price. I really recommend this product for projects around the house , (is working as it should in UK electrical network)

Using this on my boat to switch between inverter and mains. Not it's intended use but perfect for switching to shore power just by turning the inverter off Had this working for a couple of months now and delighted with it. Excellent build quality and easy to install. I bought the 3 pole version which I assume is intended for 3 phase but the extra poles are useful for switching, in my case, battery charger which is only used when on shore power and which otherwise could inadvertently be switched on when on inverter. Considerably cheaper that the manual switch it's replaced too

I ordered two of them, one was working well and is very useful, while the other one was faulty. I had to return it back, and claim a refund. The issue with the faulty one is same as reported by others in reviews. The LED light is blinking, meaning that power is recognized as out of range, while it's not. To verify that is faulty and not a normal operation, I had to connect both into the same circuit. There are several reviews reporting that issue, and is really worrying because that would mean that the supplier might have released some faulty products in the market without testing. UPDATE: I have reordered a replacement and is in good condition. So, two out of three are working perfectly fine, and only one of them for me was faulty. Compact size and easy to connect, although a bit noisy. I will buy it again, as long as it is in good condition it does the job.

Been 6 months, works great...

So far, works perfectly! Well made and easy to install. Used to auto switch between EHU and Inverter on a motorhome.

Does not work on uk voltage as the average uk voltage is 245vac

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.

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

Działa z przetwornica która ma modyfikowany sinusoid.

Extremely fast switching over lights don't even flicker nearly, when switch back load are powerless for half a second, so any computer or routers/LAN switches needs to be reprogrammed as reboots as if this, unless a laptop with internal battery ups. Easy to and simple to connect as don't need any extra cables. Shows power states in 1 in 2 and out. Works great for lights but not if have computers or 'stupid kitchen stuff that have clocks or other programming' as needs to be reprogrammed. It's a pity that can't even manually safely switch as that way creates even longer power losses. Ok, but not perfect for my use.

Ottimo prodotto e buon compromesso tra costi e qualità. Funziona sia in modo automatico che manuale.

... bis dato musste ich im Wohnmobil zwischen Inverter und Landstrom per Hand umschalten. Das war etwas umständlich, weil der Schalter bei der Eingangssteckdose unter der Sitzbank war. Jetzt geht das automatisch und funktioniert perfekt. Wunderbar. Ich kann euch gerne weiter empfehlen.

Parfait très bon produit
