Safety Regulations

To avoid electrical shock, do not open the cabinet. Refer servicing to

qualified personnel only.

To avoid injuries, always disconnect power, discharge circuits, and

remove external voltage sources before touching components.

KEEP AWAY FROM LIVE CIRCUITS.

We cannot accept responsibility for any direct or indirect financial

damage or loss of profit that might occur when using the power supply.

The instrument chassis and cover must be connected to an electrical

ground.

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.

Power

100%

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.

Example:

Features

Bright, easy to read display

Low ripple and noise

10mV/1mA resolution over the full range

Digitally controlled, mixed linear/switching mode DC power supply

Output ON/OFF Control

Very compact size and light weight

High reliability due to OVP, OCP and OTP (over voltage, over

current, over temperature) protection

Store/Recall 100 groups with 4 sets of Volt/Amp memories each

CV (Constant Voltage) and CC (Constant Current) operation

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.

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.

voltage and current value. Default

setting are OVP=61V and OCP=5.1A.

Note

This function locks the keyboard to prevent unintended modification of power

supply settings. Press (Shift LED will be lit), followed by the (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.
