3 kW Power Supply


Model 150-0040 is a 3 kW e-Gun power supply. Redesigned and upgraded, it replaces our 150-0030 power supply. All controls are remotely located in a handheld remote control (including a meter to read both voltage and current). This unit features closed-loop filament control and beam stabilitization that allow for better evaporation at lower emission rates. It can be operated manually or remotely by a rate or signal monitor. Interlocks are provided to assure power shut off in the case of water stoppage, vacuum failure, or high voltage access.

See Hanks HM2 e-Gun Accessories for additional feedthroughs.
