What does „stabilized and peak-free power supply“ mean (cross-line laser)?

Cross-line laser modules contain sensitive laser diodes that can be destroyed within microseconds by voltage spikes and current fluctuations. Stabilized means: constant output voltage under load, no sag during switch-on. Peak-free means: no switching spikes or overshoot on the supply line. Always use a switching power supply with sufficient smoothing or a dedicated laser diode driver. Avoid unfiltered supplies, cheap USB power banks without stabilization, and supplies shared with switching relays or motors. The DC variant of our modules includes integrated reverse-polarity protection.
