The 68938 is one of our most versatile power supplies; it runs QTH and IR sources from 0.8 to 140 W. We think that you’ll be impressed with the high performance, ease of use and economically minded price. You can set the proper operating current for your source, and then choose between current and voltage display on the LED. Light ripple is <0.4% r.m.s.

Soft Start

The 68938 has a soft start feature that protects the lamp from sudden and drastic current changes; the current gradually ramps up to the set level. This prolongs lamp life.
