20W IP67 Dimmable Constant Current LED Driver (650mA, 21-31v)

A 20W IP67 waterproof dimmable constant current LED driver (21-31v). 

This industrial power supply outputs a range of 21-31v (depending on circuit draw) whilst retaining a steady 650mA current flow at a precise +/- 2% tolerance. At 650mA these drivers will suit our 3W and 10W LEDs (assuming correct circuit calculations - if in doubt, please ask). 

Built with only US and European brand name components and with 3 type of circuit protection, these safe and tough LED drivers carry a 5 year manufacturing warranty and provide an excellent solution for a wide range of LED projects.  

Typical circuit : LEDs ran in series (see attached circuit diagram). Dimmed via a 0 - 10v separate dimming circuit (PWN or potentiometer). Example PWM circuit connected to a micro-controller is included as a separate image along with this listing.
