Air-Condition Solution:

Introduction:

This indoor/outdoor air-condition solution has a built-in 32-bit MCU (MDF101A), based on a single/double resistor sensor-less FOC scheme, which enables precise speed control and quiet, efficient and energy-saving operation.

Features:

 - Based on single/double resistance sensor-less FOC program to achieve precise speed control, silent operation, closed-loop starting technology to ensure fast and stable start.
 - Supports upwind/downwind switching.

 - 5-segment/7-segment SVPWM can be switched freely.
 - Multiple protection functions: over/under-voltage protection, hardware and software over-current protection, blocking protection, phase failure protection.

Applications:
