Bench Power Supplies
Genvolt bench power supplies are small form factor high voltage power supplies that consume very little space in their installation environment and are available from 30W output power to 50kV output voltage. Within this range we also have our 19-inch rack-mounted power supplies that are 3U or 4U and have output voltages from near 0kV to 120kV.

Electrostatic Precipitators
Electrostatic precipitators are efficient at removing particles from their operating environment and our highly efficient high voltage modules are either adjustable from 10kV-20kV and 150W-1000W or are supplied as fixed units with output power from 5W for the lower end range up to 1000W and 150kV for the ion blast air purification system.

Capacitor charging power supplyHigh voltage capacitor charger

Capacitor Charging Power Supplies
Capacitor charging power supplies combine high performance with the latest technology and have typical uses in pulsed power applications, atomic, defence, and nuclear research. The units have output voltages from 5kV to 200kV and rated output power from 500W to 24kW.

High Voltage Cable
Genvolt offers a variety of high voltage cables, including shielded cable, unshielded cable, x-ray cable, triaxial cable, multi-conductor cable and silicone cable, with rated voltage up to 300kV (DC).

High Voltage Connectors
If you have high voltage power supplies and are in need of connectors, our selection of high voltage connectors up to 60kV are robust, economical, constructed from Silicone and are suitable for TV type rated cable.

Electron beam power supplyPegasus high voltage power supply

Electron Beam Power Supplies
Highly stable power supplies with operational uses like electron beam welding or additive manufacturing. Typical output power and voltage ranges start at 600W & 15kV for a rack-mounted supply or 3kW & 60kV respectively for a castor wheeled power supply.
