RONKONKOMA, New York — March 18, 1998 — UltraVolt Inc., a world-leading manufacturer of high voltage power supplies, today announced it has extended the "-F" series of Ripple Stripper Output Filters to include the 10kV to 30kV "A" series DC to DC high voltage power supply product line.

More than 70 models can now be ordered with the "-F" to further reduce the output ripple. Ripple reduction ranged from 25% to 50% on the off-the-shelf "10A-30A" series units. All mechanical and electrical specifications were maintained.

Examples of the output ripple improvement are:
15A12-P4-F-M (+15kV 4Watt) is now 0.03%
30A24-N30-F-M (-30kV 30Watt) is now 0.05%.
