2CS0xx0K series current sensors

Cable mounted, 50 to 600 A, bidirectional current sensors.

This cable-mounted current sensor is slipped on a high current battery cable and connected to a Lithiumate™ BMS controller to detect battery currents (such as the load current) in the range of 50 to 600 A.

Its resolution may not be sufficient for much lower currents (such as from a charger). In that case please see the in-line current sensors, with currents ranges of 5 to 20 A.

Note that some HV Front Ends already include a current sensor.

Compared to other sensors, a cable mounted current sensor:

• Can handle higher currents
• Does not drift due to self-heating
• May simplify the layout of high voltage cabling

Tamura L03SXXXD15 current sensors.

Because the desired cable length is not known a priori, the sensor comes with an unterminated cable and a connector kit. Use these instructions to terminate the cable in the field.

• Install the current sensor and the BMS controller in their final positions
• Measure and cut the current sensor's cable to an appropriate length
• Unclad the cable end 1 inch, careful not to nick the wires
• Remove the shield foil
• Strip all 4 wires 1/8 inch
• Crimp 4 C-Grid female sockets to the wires
• Slip the sockets in the 4-conductor C-Grid connector, until they snap in place

  2. Green
  3. White
  4. Black and shield bleed wire (uninsulated)

For replacement parts, see the parts list

• Slip the battery power cable through the opening in the current sensor, so that, when discharging, current flows into the side that has the signal cable (note that the arrow printed on the label is the direction of discharging current)
  • If installed backwards, you will need to toggle the "Direction" when programming the controller.
• If the cable is too large for the opening on the sensor:
  • Install the current sensor on a copper bus bar, and connect the battery cable to the bus bar, or
  • Strip the cable, run the copper strands inside the sensor, isolate the strands with heat shrink tubing
• Connect the signal cable to the BMS controller (4-pin, black connector)

Price: $ 50 when ordered as part of a system.
