Ascent MS

Multi-Output Power System for Multi-Chamber Power Delivery in Solar PV Manufacturing

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.


The Ascent MS supports up to five independent chambers of PERC PECVD deposition processes in a single unit. This optimizes power delivery, enables independent programming, and simplifies deposition machine design to help you lower capital costs and increase reliability.
