The Fusion UV P300MQ and P300MT are both microwave power supplies used to drive 6-inch electrodeless UV curing lamp systems (like the F300 series). The Fusion UV P300MQ has many of the same specifications as the P300MT, but is larger, heavier, and utilizes a an almost instant Quick Restart feature and supports the F300SQ system, whereas the standard P300MT drives the baseline F300S system.
