Description
Provides stepped voltage of 0-15V in 1V steps. A special key lock allows the voltage to be locked to a particular level or to a maximum ceiling. Continuously rated output of 8.5A, AC or DC, or added sum of 8.5A. Over-current is measured and timed for cases of serious overload and slight overload to decide tripping time. This avoids over-sensitive tripping in cases of initial heavy current surge, e.g. when using lamp bulbs. Slow-blow fuse protection for primary transformer. Additional thermal trip protection for transfomer. 5 year warranty.
