Models 9110 and 9111 are a new type of power supply. Unlike conventional

power supplies with fixed output ratings, they automatically recalculate

voltage and current limits for each setting, providing any Volt/Amp

combination within the rated power. By providing greatly expanded choices

of maximum power Volt/Amp combinations, users can cut down on the

number of power supplies required and free up valuable bench space.

Features & Benefits

The multi-ranging feature offers exceptional flexibility by providing any

combination of the rated voltage and current up to the maximum output

power of the supply. For example, when setting the voltage on the 180 W

model 9111 to a maximum of 60 V, the power supply can generate a

maximum current of 180 W/60 V = 3 A. For a 22.5 V setting, the maximum

current can be increased to 8 A. All Volt/Amp combinations that lie on the

hyperbolic curve between these settings are also possible up to 180 W.
