The High Current version is appropriate for people running electric motorcycles or similar who have a high current sense resistor already inline with their system. It is simply the CA3-DPS model but with the 6-pin connector removed and replaced with ring terminals appropriate for high amperage shunts.
The CA3.0 device allows you to control your bike and add PAS/Torque control modes, motor temperature sensing, or power/current limiting.
Dimensions: 128 x 57 x 26mm
140cm cable terminated with ring terminals for connection to external shunt
Comes with speedometer sensor and spoke magnet.
There is an Optional Shunt for reading battery current.
Get instant readout of speed, Amps, Watts, voltage and more. The new model has a variety of new feaures including Data Logging: Devices have a serial output stream that can be used for real-time recording the vehicle statistics to a computer or laptop (see manual).
| Voltage Range: | 10-150V, but derated by accessory current draw. With common torque sensors on PAS plug, 60V max |
| Current Range: | + - 240 mV/Rshunt. So for instance, with a 2mOhm sense resistor, the maximum current is 120 amps. With a 0.5 mOhm sense resistor, up to 480 amps, and so forth |
| Current Resolution: | 0.01 A in low range mode, 0.1A in high range mode |
| Current Accuracy: | Temperature coefficient and accuracy depend on the shunt and calibration. With the pre-calibrated Stand-Alone model, it is within 2% +- 0.04A. |
