Power supply 12V with battery - superG - 10-10-2021
Hello,
For my setup; I want to use an AC/DC 12V with an integrated battery (Kincony used in combination of my alarm system and domotic modules)
I was thinking to use the MeanWell DRC-40A but the voltage is slightly above 12V.
Is the input tolerant to 13V (voltage of the battery in float mode).
I have:
- K868-32b
- Switch terminal board 2.1
Edit:
- Terminal board 2.1 is OK as it use the ST 78M05 linear circuit power which has a 35V Max absolute input
- That also means the chip will dissipate more power to drop down to 5V ( 16% more)
Thanks

no problem, H32B use "TPS54331" power IC. the delay is DC12V, if use for DC13V will no problem.
