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:
V
When setting the voltage to the maximum
value of 60V, the max. current value is
60
100W / 60V = 1.66A. For a 10V setting,
the max current is limited to 5A, in which
40
case the maximum output power is only
50W.
20
A maximum output power of 100W is
possible for all V/A combination that lie on
the hyperbolic curve.

Installation
Unpacking the instrument
This instrument was carefully inspected before shipment. Upon receipt,
inspect the instrument for damage that might have occurred in transit. If any
sign of damage is found, notify your B+K Precision distributor.
Check the list of supplied items
Verify that you have received the following items with your power supply. If
anything is missing, contact your authorized B+K Precision distributor.
- Power cord
- Instruction manual
Power Requirements
The 9110 can operate on 110V AC or 220V AC. Before connecting the power
cord to an AC outlet, make sure the voltage selector in the rear is set to the
correct line voltage.
If necessary, replace fuses according to this table.

110V AC
198V to 242V
T0 3.15A, 250V
220V AC
109V to 121V
T0 2.5A, 250V
The instrument power fuse is located in a fuse compartment below the AC
input receptacle. To access the fuse, first disconnect the power cord and then
remove the fuse cartridge.
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.
Quick Start
Set Voltage
Set Voltage
Press the D V/A key to turn the “V”
indicator on. Now you can set the voltage
B
value. Use the cursor keys A
to highlight the desired digit then adjust
its value with the knob.
In this example the cursor is set to
position B and the voltage value can be
adjusted in 1V increments.

the output is turned off. Each time you
press the On/Off key, the display will blink
for 3 seconds and the set value for Volts
and Amps is displayed. Afterwards, if
the instrument has been set to ON, the
actual output values for voltage and
current are displayed.

Check the Set Voltage and Set Current Value
The power supply usually displays the actual voltage and current value. Press Shift
twice to check the set value for voltage and current. The display will blink for 3
seconds while displaying the set values.
Key Lock Function
This function locks the keyboard to prevent unintended modification of power
supply settings. Press Shift (Shift LED will be lit), followed by the C (Lock)
key. Now the keys and the knob are locked and the Lock LED is lit. Press the
Shift key followed by the Lock key again to disable the Lock function.
OVP Function
Press
then press and hold the
D V/A
(Setup) key for 3 seconds.
Afterwards the LCD will display OVP
and you can adjust the OVP value using
