Introduction)
!
!
The 9110 and 9111 are unlike conventional power supplies with
fixed output ratings. They automatically recalculate 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 (or 180W, 60V or
8A for 9111) 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 (9110): 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.
