The spec calls for a 12v at 50mA which is .6 Watts. My broken remote system has a 22VAC at 30mA which is .66 Watts. Will this be acceptable to you switch mode power supply?September 13, 2018 at 8:24 am #12798
I’m afraid not.
Our relay are at 5Vdc (this is by using onboard switching power supply to down convert voltage).
When at 12Vdc, Our receiver unit standby current is ~12mA, and each relay consumes ~70mA.
So when one relay on, current is ~80mA, while when both relays on, current is ~150mA.
So you will need a bigger power supply, such as those commonly seen 12Vdc 1A (or 0.5A) ones.

My old garage door opener apparently does not put out enough power on its 12-24v circuit as when I wire receiver to the wall switch nothing happens. ( opener is over 30 years old.) Where can I get a 12vdc power supply that will work with 202U5?November 20, 2018 at 8:47 am #12907
For example, should work.
You can find plenty of them on market, I’m not affiliated with above seller in anyway, thus can’t guarantee its quality etc.
