N3331N Posted July 19 Share Posted July 19 Hey, is it possible to use the device with 24V „AC“ devices without killing it? I do not care about power measuring. I want to use the rgbw as a controller for my sprinklers valves in the garden. thx N3331N 1 Quote Translate Revert translation?

Heinz Posted July 19 Share Posted July 19 I dont think it can as the AC current alternates and could damage the device. From what i know its only designed to run on DC current 1 Quote Translate Revert translation?

Members thgoebel Posted July 19 Members Share Posted July 19 (edited) Connecting a Shelly plus RGBW PM to AC will definitively kill the device: E.g. the four MOSFETs at its outputs have intrinsic body diodes which will fail at the negative half-wave. Moreover, there is no articulated rectifier at the supply input if I remember correctly. Edited July 19 by thgoebel 1 2 Quote Translate Revert translation?

Shelly Shelly Wave help Posted July 19 Shelly Share Posted July 19 The best device to use for the 24 AC is the Shelly Plus 1 or the Shelly Plus 1 Mini. They have a dry contact relay where you can connect the 24 V AC, you will need an alternative power source to power the Plus 1 or the Plus 1 Mini. Quote Translate Revert translation?
