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:

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.

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.

FuseRangeLine voltage T0 3.15A, 250V99V to 121V110V AC T0 2.5A, 250V198V to 242V220V AC

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

Press the key to turn the “V”

indicator on. Now you can set the voltage

value. Use the cursor keys

to highlight the desired digit then adjust its value with the knob. In this example the cursor is set to position and the voltage value can be

adjusted in 1V increments.

Set Current

Press the key to turn on the “A” indicator. Now you can set the current value. Use cursors to highlight the desired digit then adjust its value with the knob. In this example the cursor is set to position and the current value can be adjusted in 1A increments.

will blink simultaneously. Press one of the

V/ADV/A

keys to assign one of the 4 available memory location within this group. Proceed accordingly for the other 3 sets.

Preset Mode

Press followed by the (Preset) key. The Preset LED will turn on to indicate

ShiftShift

Trouble shooting hints

If the output is disabled

1. Check if the voltage and current values are zero. If set to zero, set the voltage and current value again.

2. Check if the OFF indicator is lit. If so, press the key to turn the output on.

3. Check if the OCP or OVP indicator is lit. If so, set the OVP or OCP value
