OT FIT is a flicker-free dimmable constant current driver that's compatible with the most common leading-edge and trailing-edge phase dimmers. Suitable for indoor SELV installationsand for use with class I and II luminaires.

Key Info:
- Compatible with the most common leading-edge and trailing-edge phase dimmers
- Flexible current setting (DIPswitch – 2 to 4 currents)
- Flicker-free dimming
- Higher quality of light thanks to < 5% output ripple current
- Housing from 80% recycled plastic

Delivery is 2-3 working days.
