The Model 864 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 1500V.
The simmer trigger output provides an SCR discharge of 250V at 63mJ to drive a trigger transformer.
When the lamp is struck, the trigger pulses are inhibited and the supply provides a constanct current to the flashlamp.
Immidiatly after PFN discharge, the current is boosted automaticaly to maintain the arc.
An external ballast is not normally required.
Input Voltage: +22DC to +32VDC
Output Current: 500mA
