Summary of DC ELECTRONIC LOAD TO BANANA ADAPTOR
This multi-purpose adaptor converts a DC electronic load terminal to banana connector cables, includes solder pads for harnesses and an optional integrated low-side shunt current sense with a BNC output for low-noise oscilloscope viewing of current waveforms. Ideal for observing fast load or current transients.
Parts used in the DC Electronic Load to banana cable adaptor:
- Adaptor board with banana connector mounted
- Solder pads for harnesses and voltage sense wires
- BNC connector (J3: 5-1634503-1)
- Shunt resistor (R1: LVK24) — 20 mOhm, 1 W (optional mounted)
- Low-pass filter resistor (R2: 1 kOhm, 0805 size) — part of 16 kHz filter (optional mounted)
- Low-pass filter capacitor (C1: 10 nF, 0805 size) — part of 16 kHz filter (optional mounted)
- Low-side shunt current sense circuit (locally filtered)
DC Electronic Load to banana cable adaptor
This product is a multi-purpose DC load terminal to banana cable adaptor. It includes solder pads for direct soldering of harnesses to the DC load output (convenient to add voltage sensing wires or wires from a power supply for battery emulation). Additionally, it has a fully integrated low-side shunt current sense circuit, locally filtered and outputted on a BNC connector. This allows viewing of the current waveform directly on your scope with extremely low noise.
This product is ideal for anyone that works with fast load or current transients and would like to observe those on an oscilloscope.
Options
This product can be sold in two options:
- [Adaptor only] The adaptor board is shipped only with banana connector mounted. The board can be used out of the box as a DC load terminal to banana cable adaptor and solder pads. The current monitor circuit (BNC connector, shunt resistor and low pass filter) are left unmounted. The buyer is free to mount his own BNC connector (J3: 5-1634503-1) and preferred shunt resistor (R1: LVK24) and low pass (C1, R2: 0805 size).
- [Adaptor with current monitor] The adaptor board is shipped fully mounted with a 20mOhm/1W shunt resistor, 16kHz low-pass filter (1kOhm, 10nF) and the BNC connector installed. This corresponds to 20mV/A rated for 7A. This is the ideal option if you would like to observe load or current transients on an oscilloscope.

- What does this adaptor do?
It converts a DC electronic load terminal to a banana cable adaptor and provides solder pads for harnesses and optional current monitoring via BNC. - Can I add my own voltage sensing wires?
Yes, the board includes solder pads for direct soldering of harnesses or voltage sensing wires. - Does the product include a current monitor by default?
There are two options: adaptor only (no current monitor components mounted) or adaptor with current monitor fully mounted. - What is the shunt resistor value when the current monitor option is selected?
The mounted shunt resistor is 20 mOhm rated 1 W, giving 20 mV/A. - What low-pass filter is used for the current monitor option?
The mounted low-pass filter is 16 kHz implemented with 1 kOhm and 10 nF (0805 size). - How is the current output delivered for oscilloscope viewing?
The locally filtered current sense is output on a BNC connector for direct oscilloscope connection. - Is the adaptor suitable for observing fast current transients?
Yes, it is ideal for viewing fast load or current transients on an oscilloscope. - Can I install my preferred shunt resistor and BNC myself?
Yes, the adaptor only option leaves the BNC, shunt resistor, and low-pass parts unmounted for user installation.
