High Voltage Power Supply Modules

The Series OL400W range of single output high voltage power supplies meets the exacting requirements found in electron and ion beam systems.  Designed using the latest power switching IGBTs to ensure efficient and reliable operation over the full operating range, the Series OL400W will give excellent performance in the most severe of electrical environments.  The 1U construction (2U for 80kV units) allows operation at full power when close mounted in a standard equipment rack, giving significant savings in rack space in large systems.  Please note that the 80kV unit utilizes an encapsulated HV section.
