Introduction

The 9110 is a new type of power supply. Unlike conventional
power supplies with fixed output ratings, the 9110 automatically
recalculates voltage/current limits for each setting, forming a
constant power hyperbolic shaped boundary as illustrated in the
diagram below. Any Volt/Amp combination that doesn’t exceed
100W, 60V or 5A can be set. By providing greatly expanded
choices of maximum power volt-ampere combinations, users can
cut down on the number of power supplies required and free up
valuable bench space.

Example:

When setting the voltage to the maximum
value of 60V, the max. current value is
100W / 60V = 1.66A. For a 10V setting,
the max current is limited to 5A, in which
case the maximum output power is only
50W.

A maximum output power of 100W is
possible for all V/A combination that lie on
the hyperbolic curve.
