Safety Summary The following safety precautions apply to both operating and maintenance personnel and must be followed during all phases of operation, service, and repair of this instrument. Before applying power to this instrument: • • • • • Read and understand the safety and operational information in this manual. Apply all the listed safety precautions. Verify that the voltage selector at the line power cord input is set to the correct line voltage.
to the primary power entering a building or other outdoor wiring. Do not use this instrument in an electrical environment with a higher category rating than what is specified in this manual for this instrument. You must ensure that each accessory you use with this instrument has a category rating equal to or higher than the instrument's category rating to maintain the instrument's category rating. Failure to do so will lower the category rating of the measuring system.
Do not operate the instrument in the presence of flammable gases or vapors, fumes, or finely-divided particulates. The instrument is designed to be used in office-type indoor environments. Do not operate the instrument • • • • • • • In the presence of noxious, corrosive, or flammable fumes, gases, vapors, chemicals, or finely-divided particulates. In relative humidity conditions outside the instrument's specifications.
Do not clean the instrument, its switches, or its terminals with contact cleaners, abrasives, lubricants, solvents, acids/bases, or other such chemicals. Clean the instrument only with a clean dry lint-free cloth or as instructed in this manual. Not for critical applications This instrument is not authorized for use in contact with the human body or for use as a component in a life-support device or system. Do not touch live circuits Instrument covers must not be removed by operating personnel.
ratings, and current ratings specified in this manual or on the back of the instrument. Failure to do so may damage the instrument, lead to a safety hazard, or cause a fire. Failure to use the specified fuses will void the warranty. Servicing Do not substitute parts that are not approved by B&K Precision or modify this instrument. Return the instrument to B&K Precision for service and repair to ensure that safety and performance features are maintained.

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.
Features Digitally controlled, mixed linear/switching mode DC power supply 10mV/1mA resolution over the full range Bright, easy to read display Low ripple and noise Very compact size and light weight Output ON/OFF Control High reliability due to OVP, OCP and OTP (over voltage, over current, over temperature) protection CV (Constant Voltage) and CC (Constant Current) operation Store/Recall 100 groups with 4 sets of Volt/Amp memories each 12
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.
Fuse Replacement Follow the steps below to replace or check the fuse. 1. Locate the fuse box next to the AC input connector in the rear panel. 2. With a small flat blade screwdriver, insert into the fuse box slit to pull and slide out the fuse box as indicated below. 3. Check and replace fuse (if necessary) for the desired line voltage operation (see Table 1).
Quick Start Set Voltage Press the D V/A Set Voltage 9110 key to turn the “V” 100W Multi Range 60V/5A DC Power Supply 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.
Cursor Position and Step Size Cursor position Voltage step size Current step size A 1A B 1V 0.1A C 0.1V 0.01A D 0.01V 0.001A 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.
Key sound 9110 Once the OCP value is set, press 100W Multi Range 60V/5A DC Power Supply C V to enter the BEEP mode. Use the knob to turn the key sound ON or OFF. Press C to confirm. A A B B C C D D A Set address 9110 100W Multi Range 60V/5A DC Power Supply Press twice to skip the address menu and advance to the group menu.
Storing Voltage/Current sets Store up to four sets of voltage/current values to the group number assigned in the previous paragraph. Press Shift followed by the A (Save) key. All 4 cursor LEDs A B C D A B C D V/A will blink simultaneously. Press one of the keys to assign one of the 4 available memory location within this group. Proceed accordingly for the other 3 sets. Preset Mode Press Shift followed by the B (Preset) key. The Preset LED will turn on to indicate that the Preset mode is now active.
