Electron Beam Power Supply

The Genvolt electron beam power supply range is suitable for 3D printing and additive manufacturing, laser metal deposition and electron beam welding. Consisting of high powered units, with power ranges available from 60kV up to 200kV. Both the DC filament and bias power supply are integrated within the mechanical build.

Current for the filament and bias voltages are measured at high potential, with the measurement sent via fibre optic connection to the control system.

Genvolt electron beam power supplies in corporate high power inverter technology as well as a patented rectification transformer with low stored energy and high reliability.

Circuit protection

The units can adopt either air or water cooling technologies and comes with complete in-built protection against over voltage, over current, over heat and discharge detection. This enables the unit to perform continuously over extended periods.

Control ports

User interface connector and rear panel connections

There are five sets of wiring terminals on the rear panel of the power supply, which are the ports for remote control of the power supply.

JD0 and JD1 are digital ports.

JA0 and JA1 are analogue ports.

JP1 is the supporting power supply providing 24V for external use.
