Note:
LED drivers are designed and intended to operate LED loads only.
Non-LED loading may be outside the specified design limits of our
LED drivers, and therefore cannot be covered by any warranty.
If you desire to use our LED drivers to operate non-LED loads
please contact us to discuss compatibility.
Specifications subject to change without notice.

Notes:
1. For the driver to operate properly, the load voltage must be maintained above the minimum voltage threshold
(approx. 33% of the max. output voltage for any given model).
2. If the dimming voltage is varied from 10V down to 0V, the output current can be varied from 100% Io down to 20-30% Io.
3. Do not connect the GND of dimming to V(-) or earth ground; otherwise the LED driver will not work properly.
4. If dimming is not required, connect yellow and purple leads together to get full current output (100%).
5. It is permissible to parallel driver outputs to achieve higher output currents. However, when doing so, it is not permissible to connect
dimming control leads in parallel.
6. It is permissible to connect dimming control leads of multiple drivers in parallel to allow them to operate from a single 0-10V control.
However, when doing so, it is not permissible to interconnect output leads (red and black) across drivers.
