Level 12 Power Supply

[davetheglitz]

I've just bought a level 12 0-10v desk - supposed to need 20v 85mA PSU - seems a heavy PSU for 0-10v out. Can I get by with 15v from my dimmer pack? If not - where can I get a suitable PSU?

 

Thanks

The +20V PSU is specced for a maximum of 5mA on all 12 of the 10V outputs, plus a bit to run the actual desk. If your dimmers sink less than 5mA per control channel, then you don't need such a big PSU. Yes you can use the supply from the dimmers, that's what it's there for. Be careful to check the voltage, polarity and pinouts are compatible, as this is a notorious problem area with analogue control.

 

The higher voltage on the PSU is to allow for cable losses & low mains voltages, in reality a good +15V supply should work OK.

Paul, Thanks for your quick response. I've now wired up a control cable, and the whole thing works a treat!

 

Cheers
