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.

Note:
Disconnect power to LED driver for at least 30 seconds before con-
necting or disconnecting Driver output and LED Engine. This prevents
potential arcing transients that can damage the Engine and Driver.
