Can someone who owns a HDMI TO SDI mini converter tell me the amperage of the factory power supply? Thnx

All our Mini Converters use the same power supply.

These have 100 to 240V AC input and 12V 0.84A (10W) DC output. The center pin is positive.

I hope this helps.

Is it possible to power those 12v mini converters with an anton bauer battery with its 14,4v?

I see, cause I lost my power supply for the HDMI to SDI converter. So I plugged in the SDI to HDMI factory power supply, and it doesn't light up...

Yes it should be fine, but not with more than 15 Unless you have one of the Analog to SDI2 or HDMI to SDI2 (check serial number) units, then the voltage can be a bit higher than that.

The power supplies for all the Mini Converters are the same, so this should work. That is unless you connected a bigger power supply and it got burned up. But if connecting the factory power supply shows no power light, then you'll need to contact support about getting a potential RMA.

I mistakenly was trying a 12v 1.5 amp power supply for the converter (hdmi to sdi) and it turned on (and ran very hot).
But upon now plugging in the .84 amp power supply (sdi to hdmi mini) it doesn't power up the converter (hdmi to sdi)

Stummped.
