After the G400 doorbell was launched, some users reported that using an 8VAC power supply could not drive the doorbell properly (especially when starting the infrared light at night, it would immediately restart). Among them, European users gave the most feedback, and we have collected some power specifications that cannot drive the doorbell properly, as shown below:
The official power specifications for G400 are 8-24V AC 1.3A 50/60Hz or 8-24V DC 0.8A, which means that in AC power mode, the minimum output power of the transformer needs to reach 8V × 1.3A=10.4VA. We actually tested that G400 can also work stably under 8V/1A (power 8VA), provided that there are no other loads on the wire.
But currently, most users who are still using the 8V/1A power supply are still experiencing power shortage issues. If your home’s weak current system happens to be using the 8V/1A, please let me know the load situation on the line (whether other low-power appliances or electrical devices are connected in series or parallel). Can you assist in measuring the voltage on the power supply after G400 is powered on? If you can provide relevant information, I would be very grateful.
