asiair@zwo I'm having a similar problem but with the ASIAIR Plus. The voltage drops dramatically (from 11,8 to 10,9V) when the camera cooler starts to consume power (24W). The camera is the 2600MC Pro powered from ASIAIR Plus external 12V DC outputs.
The ASIAIR is powered from 220V AC grid through a 12V DC 10A (120W) transformer.
Any help is welcome.
Thanks in advance.
