Core Advantages

1. Wide - temperature Operation
Both products can operate within a temperature range of - 40°C to 150°C, with some parameters selectable. This temperature - resistant capacity far exceeds that of conventional products.
2. High Reliability
They have a service life of up to 1000 hours and are equipped with multiple safety mechanisms such as short - circuit protection (short - circuit trip current: 8 Arms, 16KHz) and ambient temperature detection (with built - in sensors).
3. Flexible Control
They support various motor control strategies, such as six - step commutation control. The 48V model also supports Field - Oriented Control (FOC). There are multiple feedback methods available, like Hall sensors, Electromotive Force (EMF), etc. The 48V model additionally has a transformer sensor feedback.
4. Convenient Communication
Both support RS485 and CAN communication protocols, which makes it easy to integrate them into systems.
5. Application - specific Design
These products are specifically designed for the motor control of the micro - electronic controlled hydraulic power systems in intelligent downhole tools, making them suitable for specific professional scenarios.
