60 W, 500 mA Flashlamp Simmer Supply

Model 864A Flashlamp Simmer Supply

Model 864A Simmer SupplyThe Model 864A Simmer Supply is designed to strike and maintain a low-level current discharge in flashlamps.  Initially, the simmer output open circuit voltage rises to a stabilized 1500 V.  The simmer trigger output provides an SCR discharge of 520 V at 63 mJ to drive a trigger transformer.  When the lamp is struck, the trigger pulses are inhibited and the supply provides a constant current to the flashlamp.  Immediately after PFN discharge, the current is boosted automatically to maintain the arc.  An external ballast is not normally required.

Model 758B.1

Based on the field proven performance of AMI’s 758 Series Laser Rangefinder Receivers, the Model 758B.1 extends the capabilities even further with outstanding double-pulse discrimination. This allows a weak target to be seen through a close, partly obscuring strong target. Multiple Target Resolution is 12 meters typical over 6 orders of magnitude with the second pulse 10dB down.
