CR Series is designed for low voltage,48V~96V, motor applications in low speed electric vehicles (EV) and industrial EVs, which can drive various types of motors, including induction motor (IM), permanent magnet (PM) motor, and BLDC motor, so the CR Series can be integrated with various systems.

There are several hardware design features in CR Series. The use of low-loss MOSFETs and the increase of PCBA copper thickness lead to high performance and efficiency of the controller, which improves the driving range and alternatively saves initial battery cost. The metal core PCB (MCPCB) design in CR Series provides better thermal conductivity that helps the cooling of the controller. Its safe electrical insulation guarantees to withstand breakdown voltage up to 1500Vac.

CR Series features a comprehensive allocation of multi-function I/O including analog inputs, digital inputs, contactor coil drivers and proportional valve drivers. The CAN 2.0B interface connection allows communication with other devices.

A field-oriented control (FOC) technique is implemented in motor control to provide fast response. Its SMARTuning® software, with auto-tuning function, enables users to optimize new system applications to perform the motor characterization in place at less cost and time to the market.

The compact size of the controller makes it easy for system integration, and its robust design, with high IP rating, enables the motor controller to operate in a harsh environment. CR Series is designed and manufactured at the utmost quality to meet performance, safety, and reliability requirements.
