MCx1101 evaluation board (EB0013)
Evaluation board for MCA1101 and MCR1101 current sensors, with screw terminals and BNC outputs.
- For MCx1101 ICs
- BNC VOUT / VREF
- 50 A peak, 35 A RMS
- 4 oz copper PCB
Overview
The EB0013 evaluation board provides a simple way to evaluate the MCx1101 family of current sensor ICs. It is a double-sided PCB with 4 oz copper for a low resistance primary current path, with an 8-pin connector and test points for the secondary side signals and two BNC outputs for VREF and VOUT. A board version is offered for each MCA1101 and MCR1101 current range and supply voltage.
Built for
- Bench evaluation of MCx1101 sensors
- Measuring VOUT and VREF on an oscilloscope
- Testing the overcurrent fault output
Key features
Low resistance path
Double-sided PCB with 4 oz copper carries the isolated primary current.
BNC outputs
Two BNC connectors give low noise VREF and VOUT channels for test equipment.
Signal connector
8-pin P1 connector and test points for VOC, VCC, VOUT, VREF, GND and FAULTB.
Screw terminals
Primary current wires fix to I_IN and I_OUT by screw.
Thermal limit
Rated to 50 A peak and 35 A RMS; pulsed current is used for 35 to 50 A tests.
