Frequently Asked Questions

What is the dimming range of this LED driver?

The LED driver supports 1% to 100% dimming range using analog or PWM dimming signals. This wide range enables flexible lighting control from bright task lighting to dim ambient lighting.

1-100% dimming range suitable for most commercial and industrial lighting applications.

What is primary-side regulation?

Primary-side regulation senses output current indirectly through the transformer primary, eliminating the need for optocoupler feedback. This reduces cost and improves reliability while maintaining good current regulation accuracy (typically ±5%).

Primary-side regulation reduces cost and improves reliability for LED drivers.
