If you like I can check tonight when I get home with an amp meter. Personally I think running close to the rating (10 amp) will be problematic for longevity of the module.

Tried Gold Wings with topper and X-files (DMD title).

Both are fully LED, both pulled around 1 amp at idle. The Gold Wings would peak out around 2 amps while being around 1.5 the majority of the time, the X-Files seemed to peak at 2.5 amps and was 1.6 to 1.8 majority.

If you had three DMD machines being utilized at the same time I'd be concerned if they are on a 10 amp remote as you are operating at the units upper rating under hard play. Running any electrical device at 100% of rating usually courts failure sooner rather than later.

You may wish to consider a back up power supply with master and slave outlets. When the device plugged into the master outlet shuts down it kills the other outlets. I have an APC unit that does this hooked to the living room flat panel. When the TV is off, it kills everything else in the home theater setup which is a lot with 2 media players with 2 hard drives, 5.1 speaker setup with sub-woofer, 2 or 3 game consoles, controller chargers, etc. The vampiristic energy losses from items that are ostensibly "off" can be higher than you think.

Edit: You can also buy "power strip" style units without the battery and do the same thing. Just do a search on Amazon for power strip with master/slave outlets. Several are rated for 15 amp service.
