The EY series of 1200 W high voltage power supplies from XP Glassman
A series of rack mount high voltage DC power supplies able to supply up to 60 kV is said to offer superior control and enhanced performance.
Introduced by XP Glassman, the EY series of 1200 W high voltage power supplies is particularly suited for use by laboratories and original-equipment manufacturers. The series features flexible embedded controls with low ripple and noise. The units are air insulated, fast response units with tight regulation and extremely low arc discharge currents.
For use in medical, industrial and general high voltage areas, the most important applications for the EY series are in vapour deposition, ion implantation, glow discharge, electrostatics, plasma sources, cyclotrons, X-ray and other vacuum tubes.
The series comprises 16 models from 0 kV - 1 kV to 0 kV - 60 kV at 1 200 W output power. Typically, ripple is less than 0.02% RMS of rated voltage at full load and off-the-line pulse-width modulation provides high efficiency and a reduced parts count for improved reliability. The first four models in the range feature reversible polarity and the others are available as positive or negative polarity units.
XP Power’s EY series power supplies feature automatic crossover from constant-voltage to constant-current regulation, providing protection against overloads, arcs, and short circuits. The power supplies’ arc quench feature ensures that the HV output is inhibited for a short period after each load arc to help extinguish the arc and the remote analogue and digital control by means of RS232 and USB capability offers flexibility of integration with customers’ systems. Optional ethernet control allows for remote control and monitoring.
The EY series’ bench/2U rack mount format makes it suitable for location on a test bench or for integrating with other equipment in a standard 19-inch rack. Features such as embedded microcontroller control and front panel digital encoders on the units provide high resolution local adjustment of voltage and current program.
The power supplies are designed to be versatile and can operate from single phase AC supplies of between 180 V to 264 V and are Semi S2-93 compliant, meeting safety compliance levels required for use in semiconductor manufacturing equipment.
