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.
Quick Start Press the Set Voltage D V/A Set Voltage 9110 key to turn the “V” CV CC OVP OCP 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.
Once the OCP value is set, press 9110 Key sound C to enter the BEEP mode. Use the knob to turn the key sound ON or OFF. Press C to confirm.
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 B C D V/A will blink simultaneously. Press one of the A 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.
