How come my power supply is not charging the ring video doorbell at all?
The Ring PRO doesn't charge as it doesn't have a battery. If you have an original Ring, Ring 2 or Ring 3, it charges it slowly, like a trickle charger. Over time it will charge the battery and maintain a full charge once fully charged.
I connected this device to my doorbell pro but in the device health it states poor voltage... any way to fix this?
The key is the white light ring on the unit. If it is lit, then it is getting the correct power. The power supply has been tested thoroughly to power the Ring under all operating conditions. The Ring app often provides a finicky indication of poor voltage. It may change during the day to good or very good. If your Ring is working, the Power Supply is doing its job well regardless of the voltage indication in the app.
Ring states on its support page that a 25 ohm 50 watt wirewound resistor is required with the ring doorbell 2 when using a low voltage AC transformer. Does the Ohmkat power supply have the 25 ohm 50 watt wirewound resistor incorporated? (https://support.ring.com/hc/en-us/articles/115003495766-How-to-Connect-Your-Ring-Video-Doorbell-2-Directly-to-a-Low-Voltage-Transformer-Without-a-Pre-existing-Doorbell-) I have a friend who connected a low voltage power supply to their ring doorbell and after a few weeks, the ring doorbell would only work on battery and no longer on the power supply. Thanks!
Yes, the ohmkat power supply integrates the necessary resistor in transformer box. All necessary protections and electronics are included. It is a simple plug and play installation.
Will it work in -25C
