FAQ01983 of Power Controllers FAQ

A constant-current model will sometimes not be able to perform control if used with a current load much smaller than the rated current.

Possible Countermeasures:

1. Adjust the CUR LIM adjuster until one of the level indicators turns OFF.

2. If using 50% or less of the rated current, increase the number of turns of the wire on the CT.

Example:
50% of the rated current: 2 turns
25% of the rated current: 4 turns
