The PerkinElmer PS-1120-1 is a DC input variable output power supply engineered to deliver regulated, low-ripple power for 1100 Series High Stability Short Arc Xenon Flashlamps and Lite Pac Trigger Modules. The unit performs dual functions: controlled charging of the flashlamp discharge capacitor to a precise voltage, and trigger capacitor charging with switching logic for flash rate control. Built for laboratory and research environments demanding repeatable discharge characteristics and precise power management.
