Anton Bauer Tandem 70 won't power Epic Dragon?

[PC Greene]

Hello!

I recently acquired a used Tandem 70 -

Which would not power the camera on my first test *without* a battery attached. Does anyone know if this device requries a battery be mounted in order to act like a power supply when getting wall power, or could there be something wrong with my unit?

Thank you...

I have the Tandem 150 and it can power my Scarlet-W via the DSMC2 Gold Mount Module Pro without a battery attached. I used to have the Tandem 70, though I have not used it with a RED but it should work the same as the Tandem 150.

Just checked the specs, the Tandem 150 can provide 150 watt power when 75 watt draw is exceeded, while the Tandem 70 can only provide 70 Watt power. The AC adapter came with the camera is rated at max 150 watt, it might be the Tandem 70 does not have enough power for the RED.
