CV 12SLX—Stable Power Output for Single or Dual Guns

The Temescal Model CV-12SLX is a 12-kW, constant-voltage switching power supply designed to power and control a single electron beam source. The CV-12SLX power supply is compatible with sources featuring permanent or electromagnetic deflection. Delivering up to 10 kV at 0–1200 mA, the model CV-12SLX makes it possible to achieve substantial deposition rates in production environments. The power supply also offers stable output at all voltage levels, rapid arc recovery, ease of integration, and safety and convenience for operating as well as service personnel.
