Details

The Korad KEL103 connection board is a dedicated accessory for the Korad KEL103 programmable DC electronic load. It breaks out the KEL103 front terminals to a set of common connectors, so you can connect power supplies, DC jacks, battery packs and test leads quickly without re‑wiring each time.

The board provides 4mm banana sockets, multiple DC barrel jacks, screw terminals and a range of small‑connector footprints such as PH, XH, Picoblade and pin headers. Two BNC outputs are available, one with an RC filter (100nF + 47µF, <50V) and one unfiltered, allowing you to monitor the load input on an oscilloscope or other instrumentation. A switch selects whether the filter is in or out of the circuit.

The PCB has a 6mm mounting hole and a slotted mounting area that accommodates a range of centre‑to‑centre distances, so the board can be fixed mechanically close to the KEL103 or to a test jig. This keeps wiring short and reduces the chance of loose leads during repetitive tests.

Note: This board is intended to be used together with the Korad KEL103 programmable DC electronic load, and the necessary cables and test leads for your application. For suitable cables, clamps and adapters, see our accessories .
