CVI Melles Griot 05-LPL-340-065 Laser Power Supply

The CVI Melles Griot 05-LPL-340-065 is a switching-regulated laser power supply engineered for Helium Neon (HeNe) lasers. It delivers stable constant current output with exceptionally low ripple - less than 0.30% rms - to ensure consistent laser performance across operating cycles. The unit accepts dual-voltage input (115/230 VAC ±10%) at 50–60 Hz and achieves conversion efficiency exceeding 75%. Automatic protection circuits guard against frequent arc discharges, output terminal shorts, and critically low input voltage conditions. A built-in bleed circuIt has additional safety compliance. The power supply features a key lock for manual control, power-on indicator lamp, and remote interlock capability via Jones plug connector (with jumper included). CDRH time delay is factory-set to 3–7 seconds.
