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 out
put power of 100W is
possible for al
l V/A combination that lie on
the hyperbolic curve.

Installation
Please inspect the instrument mechanically and electrically upon receiving it. Unpack all items
from the shipping carton, and check for any obvious signs of physical damage that may have
occurred during transportation. Report any damage to the shipping agent immediately. Save the
original packing carton for possible future reshipment. Every instrument is shipped with the
following contents:
• 1x 9110/9111 DC Power Supply
• 1x User Manual
• 1x AC Power Cord
Verify that all items above are included in the shipping container. If anything is missing, please
contact B&K Precision.

Power-on procedure
Turn on the instrument by pressing the main power switch on the front panel
of the unit. The instrument will automatically revert to the last setting before
the power was turned off.
NOTE
The 9 pin D-sub connector in the rear is for factory use only!
This instrument does not offer a remote control interface.

current value again.
2. Check if the OFF indicator is lit. If so, press the
On/Off
key to turn the output on.
