Or use a 230-V ac 50-Hz to 12-V dc adapter ifyour mains are such.You may use internal power by installing a 9-V battery inside the KPC-3 Plus (asexplained below, before doing this you need to install a battery clip (pig tail)inside your KPC-3 Plus).See Appendix E for the allowed range of voltage inputs.The steps needed for each way to supply power to the KPC-3 Plus are given below,along with detailed specification for each part needed. Of course, the parts you needdepend on which option(s) you use.The KPC-3 Plus ships with LEDs ON, so the Power indicator (LED) will turn ONwhen power is ON. If the LED value has been switched to OFF, the Power LED willjust blink once, briefly, when power is applied.External Power from Your Bench (12 V dc)Here, you will use a 2.1-mm power plug and 18-22 gauge stranded 2-conductor cable toconnect to a 12-V dc power supply on your bench. The steps are:Step 2. Build a cable by attaching the supplied 2.1-mm power plug to a user-supplied18-22 gauge stranded 2-conductor cable—connecting the center of the jackto the positive terminal of the power supply and the shell of the power jack tothe negative terminal of the power supply,Step 3. (1) Turn OFF all power, (2) attach one end of the bench-power cable to a 12-V dc power source on your bench, and (3) plug the 2.1-mm power plug intothe ―Power‖ connector of the KPC-3 Plus,Step 4. Turn ON the power supply, (2) press the power switch on the front panel ofthe KPC-3 Plus to turn your KPC-3 Plus ON, (3) confirm that the powerindicator next to the power switch goes on, and then (4) press the KPC-3Plus‘ power switch again to turn the power OFF.If the power indicator (LED) does not go on as expected, check to be sure thewiring is correct. If you have checked the wiring carefully and the power indicatorstill does not go on as expected, check or replace any fuses in line between thepower supply and the KPC. |
