150mA SIMMER CURRENT

■ 1125V OPEN CIRCUIT VOLTAGE

■ AUTOMATIC BOOST TO MAINTAIN ARC

■ UP TO 28W OUTPUT

■ SCR DRIVE FOR TRIGGER TRANSFORMER



DESCRIPTION:

The Model 867 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 1125V.
The simmer trigger output provides an SCR discharge of 350V at 20mJ 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.
For high pressure, long-arc lamps or dual lamps, Model 862A is recommended.
