Hello everybody,

Can anyone confirm that it is possible to use the OEM Control Box DC version with 24VDC?

Do I need to consider any extra concern when using the DC version of the control box? Is there any limitation?

Actually we are using the AC version and I would like to know if there are any critical differences.

Thanks in advance,

Hi @anon4739170 ,

It is OK to use 24V DC as the power source for the OEM DC controller.

You may need to pay attention to the rush current and avoid it damaging the power source.
