The manual for the BK Precision Model 9110 covers the setup, operation, and troubleshooting of a 100W multi-range 60V/5A DC power supply, including instructions on setting voltage and current, using protection features like over-voltage and over-current protection, and operating the output controls. It also provides guidance on installation, such as checking supplied items, setting the correct power requirements, and ensuring safety measures are followed to prevent electrical shock and damage.
Manual Overview
The BK Precision Model 9110 manual provides detailed guidance for operating and troubleshooting the 100W Multi Range 60V/5A DC Power Supply. The manual emphasizes safety, advising technicians to avoid electrical shock by not opening the cabinet and ensuring the device is grounded. Troubleshooting involves checking the set voltage and current values, which can be adjusted using the cursor keys and knob. Error diagnostics are facilitated by Over Voltage Protection (OVP) and Over Current Protection (OCP) functions, which automatically shut off the output if the set limits are exceeded. Calibration involves setting the voltage and current using the front panel controls, with the ability to store and recall up to 100 groups of settings. The device operates in Constant Voltage (CV) and Constant Current (CC) modes, with a hyperbolic power boundary allowing flexible voltage/current combinations up to 100W. For board-level guidance, the manual specifies that the 9-pin D-sub connector is for factory use only, and there is no remote control interface. The power supply requires a specific fuse and voltage setting, depending on the AC input.
Quick Issues Covered
- Diagnose power-up failures with fuse and voltage selector checks.
- Use error codes for OVP, OCP, and OTP protection diagnostics.
- Refer to schematics for circuit tracing and component verification.
Overview
The BK Precision Model 9110 is a 100W multi-range DC power supply with a maximum output of 60V and 5A. It features a unique design that automatically recalculates voltage and current limits for each setting, allowing for a wide range of volt-amp combinations that do not exceed 100W. This flexibility reduces the need for multiple power supplies and saves bench space. The power supply is digitally controlled, compact, and lightweight, with features such as low ripple and noise, output on/off control, and high reliability due to over-voltage, over-current, and over-temperature protection. It supports constant voltage and constant current operation and can store and recall 100 groups of volt-amp settings.

Installation / Setup
The installation and setup highlights for the BK Precision Model 9110 include:
– Unpacking: Inspect the instrument for any damage that might have occurred during transit and verify that all supplied items, such as the power cord and instruction manual, are included. If anything is missing, contact the distributor.
– Power Requirements: The device can operate on either 110V AC or 220V AC. Ensure the voltage selector at the rear is set to the correct line voltage before connecting the power cord. Fuses should be replaced according to the specified table, with the fuse compartment located below the AC input receptacle.
– Power-on Procedure: Turn on the instrument using the main power switch on the front panel. The device will revert to the last setting used before it was turned off.
– Note: The 9 pin D-sub connector at the rear is for factory use only and the instrument does not offer a remote control interface.
Operation
The manual provides basic usage steps for operating the BK Precision Model 9110 power supply. To set the voltage, press the key to activate the voltage indicator, use the cursor keys to select the desired digit, and adjust its value with the knob. Similarly, to set the current, press the key to activate the current indicator, use the cursor keys to select the desired digit, and adjust its value with the knob. To toggle the output on or off, press the designated key; the OFF LED will be lit when the output is off. The display will blink for 3 seconds to show the set values for volts and amps before displaying the actual output values if the instrument is on. The power supply typically displays the actual voltage and current values, but pressing a specific key twice will show the set values for 3 seconds. The key lock function can be activated to prevent unintended changes by pressing the Shift key followed by the Lock key. The OVP (Over Voltage Protection) and OCP (Over Current Protection) functions can be set by pressing and holding the Setup key, then adjusting the values using the cursor keys and knob. The output will automatically turn off if the OVP and OCP values are exceeded. Default settings are OVP=61V and OCP=5.1A.
