The MPS500 and MPS1500P are versatile dual source power supplies for R&D coating & cleaning applications. They can control up to two sources which can be any combination of compact magnetron sputter sources or glow discharge electrodes.
The 1500W model MPS1500P offers DC or pulsed DC mode operation with intuitive pulse with control on the graphical LCD screen.
The 500W model MPS500 also features one input for monitoring of an active vacuum gauge with interlock functionality.

Stability and Control

Extremely stable output allows for operating the sources even at low power levels (< 2W). This makes this device unique in its class and ideal for low rate and precise coating applications.
