Product Description:
The A4P series controller designed with dual-microprocessor architecture and adopted Cortex-M4F core processor with maximum 240MHz working frequency. It’s guaranteed to have high performance in terms of both functionality and robustness/safety for its application of on-vehicle traction/pump controlling.
The product has also the advantage of high compatibility for IPM/ACIM motor of majority 3rd-party brands.
Features:
- Both serial and CAN communication are enabled to ensure wider application scenarios for customer.
- Support all necessary kinds of peripheral connections, including the small power outputs, throttle inputs, digital inputs, analog voltage output, etc. which ensures the most comprehensive application for customer.
- Larger number of MOSFETs than average are adopted within the product, aiming to achieve stronger discharge capacity.
Safety and Reliability
- The innovative designs such as isolated CAN interface, isolated minus-voltage driven mechanism…etc., which ensures higher reliability for customer.
- Rich kinds of protection measures are adopted: power-fail detection, Over-voltage cutback, thermal cutback, short-circuit protection, etc., following the latest industrial practice.
- Dual-microprocessor provides a structural increase of safety and reliability.
