■ ADJUSTABLE CURRENT TO 500mA
■ ADJUSTABLE OPEN CIRCUIT VOLTAGE TO 1500V
■ AUTOMATIC BOOST TO MAINTAIN ARC
■ UP TO 60W OUTPUT
■ SCR DRIVE FOR TRIGGER TRANSFORMER
■ DIRECTIVE 2011/65/EU (RoHS) COMPLIANT
DESCRIPTION:
The
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 1500V. The simmer trigger output provides an SCR discharge of 520V at 63mJ 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.
