Excellent device – Y-A4 RF Remote Control Light Switch Reviews

Involvement:Expert (understands the inner workings) - Ownership:less than 1 day

Pros:
- Build quality is pretty good. - The receiver box is smaller than I expected - 4 channels, you can turn on/off 4 devices. - Pretty good price. - All works fine. - Good RC working range. - RC has small LED for button press indication.
Cons:
I think the main phase 220V input wire (red) to tiny for 4x1000 wattage. "- Four channels output (power 1000W x 4)" = 4kW The red wire for phase input is about 0.5-0.75mm2. http://www.diynot.com/pages/el/el004.php In table at the link: Conductor Size Current Maximum power (Watts) 1.0 mm2 10 amps Up to 2400 Watts So how it is possible to handle 4kW with so tiny wire? I think its not safe to handle so much watts. Question 2 "- Output power for each channel: incandescent lamp (max 1000W); energy saving lamp(max 200W / 6pcs at most); fluorescent lamp (max 280W / 5pcs at most)" What is the difference between energy saving lamps loaded with 200W and incandescent lamps with same 200W. I think is doesn't matter what you are using, the fact is that you're using same 200 Watts.
Other:
It's great device, works as expected, nice looking. It's worth price for this device. However I would suggest to use not very powerfull things, this is good for light lamps and some other stuff, but I really don't think that this can handle 4x1000 watts, the RED wire (phase) to tiny for that and if you load to much watts, it will be unsafe.
Bottomline:
If you wanna control some stuff at your home, buy this device, this is realy helps you.
