- OONO F-1051B Automatic transfer switch, an easy to mount 15Amp inline transfer relay provides switching between AC INPUT 2 (Utility or Shore Power) and AC INPUT 1 (Inverter or Generator) AC source. When AC INPUT 2 is powered, the load power will be switched to AC INPUT 2. When AC INPUT 2 is powered off, the load power will be switched to AC INPUT 1.
- Operating voltage AC 90 to 135V 50/60Hz. Maximum current 15 Amp.
- Transfer time less than 15mS(0.015 second). For most smart devices or computers, the switching action of 15mS time will not affect their normal operation.
- Specially optimized design will not cause your GFCI outlets to trip falsely, and it will not cause arc creepage between the two input sources and the output.
- Safe DPDT circuit switch design (Double Pole Double Throw). Live and Neutral wire are switched at the same time. The Ground wires of the two inputs and output are connected together internally and will not follow the switch on and off.
- IP68 Waterproof high level enclosure, suitable for indoor or outdoor use. Flame retardant rating V1. Case material: PC (Polycarbonate). Seal material: Silicone rubber. External screw: 304 stainless steel.
- AC INPUT 1 and ACINPUT 2 cables: Length 19 inch (0.5 meter), US standard NEMA 5-15P 3 prong plugs. AC OUTPUT cable: Length 19 inch (0.5 meter), US standard NEMA 5-15R 3 prong socket.

I tested this item before installing it, and it looked that it would do what it was supposed to do. However, after running it for about a week, it stopped powering the load. Upon inspection, I realized that the internal coil of the relay (inside the plastic case) was overheating and thus shutting down the power to the load. If you let it unplugged for half an hour, and then plug it in again, it would start working but only for a few minutes at which point it would overheat again and turn off. The most important part, which is the internal relay, is unreliable. After initially testing it, it took me a few months before I was able to install it at its final destination. Therefore I couldn’t return it because I run out of time, otherwise I would have return it.

Had planned to use this item to provide fail-over power for a refrigerator and freezer in my garage (I live in hurricane country, and have a solar system to provide backup power to critical loads).
Every time I tried to use it, it tripped the GFCI circuit in my garage, no matter which way I had it set up. Doesn’t matter if the GFCI is on AC1 or AC2… and I tested this with both a GFCI outlet, and a dedicated circuit on a GFCI breaker. Didn’t matter… it tripped both.
So buyer beware.

This ATS is in a well made box with good connections and a quality soldering job. It has a simple Puqele P30F JQX-30F relay that releases the solenoid tension when the power goes off the control circuit allowing the spring to flip the unit to backup. This is a very failsafe design. The problem is the gap between the two pairs of contacts is not great enough to eliminate a quick arcing as the power comes back on the control circuit. The chance the two circuits will be in phase is slim and about 1/4 chance they will be near complete opposites allowing an arc of 240 volts. This might be okay for some simple loads but will cause a problem for high induction loads.
The ends of my wires were pre-tinned in an unprofessional manner. It made me wonder if the unit was returned already.

Works great for hydroponics connected to solar panels.. allows u to connect solar power plus electrical grid power.. when solar energy cuts out this device switches u to grid energy.. no power interruption during the switch over.. would highly recommend for saving money on energy bills

I bought this item This transfer switch works very well exept the transfer speed could be made faster to like to 3 or 5 ms because when you have sensitive network equipment connected to it like access points they reboot every time it transfers also a smoothing filter needs to be added to make the power smoother well it transfers

This item really fit my needs, and it is really well built, but it failed to transfer power within about 60 days. It just would not transfer the load from my inverter to the AC shoreline. As this was outside the window for an tugapower.net return, I was instructed by tugapower.net to contact the supplier. Eventually, the supplier contacted me and acquired the necessary warranty information. I am now waiting for my warranty replacement.
