Dual Power Automatic Transfer Switch
63A 2P Dual Power Automatic Transfer Switch
- The dual power transfer switch is to switch two power sources, including common power supply and emergency power supply. When the common power supply is cut off, the emergency power supply starts to supply power.
- After the normal power supply comes on, it will return to the common power supply. (This is the principle of self-turning and self-recovering, and the common power supply has priority.)
- If there is no need for automatic conversion in special circumstances, you can also set it to manual switching.
Transfer Switch Specification:
- ATS Level: CB level
- Use Level: AC-33iB
- Line Voltage: AC110V
- Line Current: 6A-63A
- Operating Frequency: 50HZ/60HZ
- Insulation Voltage: AC110V
- Conversion Time: 2S or so
- Total Size: About 150×137×118mm (1mm=0.0393Inches)
- Display Function: Indicator light display
- Installation Dimension: 128mm*122mm hole: M6
Generator Changeover Switch
- Protection Function: The switch supports multiple protection functions, including short circuit, overload, phase loss, and undervoltage protection.
- Automatic and Manual: The automatic switch not only supports the automatic mode, but also can be operated by manual buttons, which is simple in operation and reliable in performance.
- Easy Installation: Reasonable structure, compact size, equipped with protective cover, power supply installation is simple and reliable.
- Wide application: The switch can be used in homes and public places, especially suitable for office buildings and public places that need fire protection.

Excuse my messy wiring in the pic, it's not the final set-up.Now the instructions could be allot better but it's a great unit. Anyway, this unit performs precisely as intended. I initially had to return my initial purchase of this switcher because it was malfunctioning. It simply didn't function properly and emitted a loud noise. I assumed it was a defective unit and got a replacement, which works flawlessly. Here's my setup: I have my solar-powered battery pack as my primary power source, with the grid as a backup. I use it to supply power to my gazebo and everything within my backyard including all the lights, ceiling fans etc. My primary goal was to run the entire backyard entirely on solar power with a seamless transition to the grid when the battery is depleted. I've tested it multiple times, and the transition is truly smooth. The lights remain stable without any noticeable flickering or disruptions.

Just enough seperation of the two gang switches in time to prevent out of phase complications between the line supply and my inverter when powered on. Hope it lasts many cycles.

I recently installed the ONASC 220V 63A 2P Dual Power Automatic Transfer Switch, and I am thoroughly impressed with its performance. This switch has made transitioning between my main power supply and generator seamless. The automatic transfer feature ensures that when there is a power outage, the switch activates instantly, providing a reliable backup without any manual intervention. This has been a lifesaver during power disruptions.The build quality is exceptional. It’s robust, sturdy, and seems very durable, with high-quality materials that ensure long-lasting performance. Installation was straightforward, and the switch fits perfectly into my electrical setup. The clear labeling of inputs and outputs made the whole process easier, even for someone without advanced electrical knowledge.What I appreciate most is the peace of mind this transfer switch provides. It works flawlessly, and I no longer need to worry about the hassle of manually switching to generator power during an outage. The 63A capacity is more than sufficient for my needs, ensuring that all my essential appliances are powered reliably.Overall, I highly recommend the ONASC Automatic Transfer Switch to anyone looking for a dependable and easy-to-use power changeover solution. It’s an excellent product for anyone who wants a smooth, hassle-free power transition during outages.

Installed this in the cargo trailer to switch from shore power (in my case a generator) and battery power. Works beautifully. Haven't had a single problem and well worth the time, effort and $$.

It worked well for about 6 months. After that, it would still switch but the amp throughput was diminished and would not run anything. You could get a voltage reading but not enough amps. Should've gotten the protection.

I was happy to pay a little more for an American product, but when I received the switch, it has a short between line and neutral when switched to the "normal" source. Obviously, it was not tested. I'll buy a cheaper Chinese knockoff instead. I hope that most US companies do better than this.UPDATE: My mistake. The resistance between L and N of the normal source is 4K Ohms, which connection I assume is used to control the automatic switch. The switch was fine.

Used the transfer switch to switch a power backup battery into a refrigerator and freezer in case of a power failure. Lots of instructions on youtube if you are comfortable extracting specific circuits from the main control board. The auto power switch is bigger and heftier than I expected but that translates into a more robust product. This switch was much better value than transfer switches you get from the local Home Depot or Lowes.

Well made switch and would be a winner, if it was not a non service switch. Must be installed after main which makes it not suitable for generator/ main power automatic switch. The switches suitable for this are very expensive,so if this switch was beefed up, it would be nice to have this option. Thank you

I use it on manual mode to control when I switch over the the generator. Only thing I did notice but not serious is a slight low buzz coming from the unit. It works, doesn't get hot so I am alright with the "AC noise"
