Photonic Sourcing

The Series OL20K is a range of high reliability products designed to meet the rigorous requirements of ion and electron beam systems. These high performance switch mode systems are based on a power converter using zero-volt switching. A full bridge of the latest generation of Insulated Gate Bipolar Transistors (IGBTs) in a fully regulated closed-loop system capable of continuously supplying up to 20kW of output power whilst maintaining flexible control down to a few hundred Watts. These highly reliable rugged systems comprise two units, a rack mounting power converter through which remote controls are facilitated, and a separate HV unit employing a modular disc construction. Numerous features are incorporated to ensure system integrity is maintained during adverse operating conditions. Such features include continuous primary current monitoring with fast pulse truncation and soft recovery, extensive thermal monitoring and automatic shutdown on key components, passive output current limiting for instantaneous surge control and independent output overvoltage sensing. Optionally HiTek Power’s Arc Count and Extinguish (ACE) system can be installed for active arc management.
