Solving the issues of high voltage and current measurement for EVs and HEVs all at once. It is a measurement module for current, voltage, and temperature with 1500V galvanic isolation.
High Voltage Measurement Module Current, voltage, power, and temperature measurements are conducted on actual vehicles and in test labs. A wide range of accessories solves wiring issues for measurements. In particular, a low shunt resistance breakout box is effective for signal measurement from the inverter to the motor. Outputs can be obtained via CAN or Ethernet, minimizing wiring. Main Applications ● Power measurement in power electronics ● High voltage electrical systems and battery measurement ● Thermocouple/RTD temperature measurement for high voltage components and batteries Features ● Four universal inputs ● Eight measurement points ● 1,500V galvanic isolation for each channel ● Auto-ranging function ● Automatic probe recognition function (similar to TEDS) ● Automatic generation of DBC/A2L ● Variable sampling rate ● Internal power calculation function (AC, DC) ● XPC-on-Ethernet 100Mbit/s communication or communication with Klaric server ● 1MBaud CAN I/F with independent 2 channels
