I have recently been obtained significant drain (10% in 3 days) on a new ring doorbell 3 despite being hardwired.
I wanted to rule out hardwiring issues. So i checked this transformer output using a multimeter.
This is my transformer
It’s currently wired on pins 1 & 4, hence I expect a 24v output. However, the multimeter was indicating a voltage of 30v. I performed readings on the rear of the doorbell and at the transformer itself (pin 1&4), both give 30v.
Do I have a faulty transformer, or is this normal?
Should I lower the voltage to 12v?
