I have a hunch your assumption is correct, Paul.

If that is an issue then use the VS-35M model with front panel adjustable
current limit that can be set from 1.5 amp up to max of the supply. The
voltage is also adjustable from front panel.
I haven't taken each apart but I wager the only difference between the
VS-35M and the RS-35M is the adjustments brought out to a knob Paul K0UYA
