The Ascent® MS is a multi-output power supply system designed to support PERC PECVD processes in the production of PV solar cells. Supporting up to five independent chambers in a single unit, the Ascent MS allows solar PV equipment manufacturers to develop cost-effective systems. Benefit from less electrical and mechanical infrastructure requirements than with other comparable solutions. With quick-connect power I/O and minimized interconnections, the power supply system optimizes power delivery while enabling faster coater installation, higher reliability, and lower costs per coater. Designed to specifically meet today’s solar PV market needs, the Ascent MS can enable the lowest system and infrastructure costs in the industry.


  • Fast track coater installation with modular power connectors, reduced interconnections, and simplified infrastructure
  • Develop cost-effective systems with less required electrical and mechanical infrastructure requirements
  • Achieve higher reliability in PERC PECVD deposition processes
  • Simplify deposition machine design with a single unit supporting up to five independent chambers
