Specifications subject to change without notice.

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.
