ISO9001:2015 OPTIONAL RS-232 OR RS-485 IS AVAILABLE HOT SWITCHABLE POLARITY REVERSIBLE VIA LOGIC SIGNAL WELL REGULATED , LOW RIPPLE POLARITY REVERSAL WITH IN 10ms VOLTAGE AND CURRENT MONITOR OUTPUTS REMOTE HV INHIBIT ARC AND SHORT CIRCUIT PROTECTED OEM CUSTOMIZATION AVAILABLE INTRODUCTION Wisman's PRA is a well-regulated high perform ance DC -DC converter featuring a“hot switchable” polarityreversal capability. The PRA's low ripple specification makes it ideal for Mass Spectrometry applications; especially security detection systems, Dynodes, sample i onizati on as w el l as capil lary e l e c t r o p h o r e s i s a n d e l e c t r ostatic printing Applications. The PRA is rated at ±8kV and is packaged in a shielded metal enclosure. This unit features a logic signal input to control output polarity reversal. A HV inhibit feature, along with voltage and current monitors are provided. Easily customized to meet OEM requirements, the PRA can be provided with improved ri ppl e performance and higher voltage and current capabilities. An optional RS-232 or RS-485 is available, optional reversal time:10ms,25ms,50ms,100ms,250ms,500ms,1s.
