SANHUA ELECTRONIC EXPANSION VALVE DRIVER (VSD2001 series )

Sanhua VSD2001 Series

1. Optimized for Commercial Power Levels

• Advantage: Specifically designed for the “mid-range” commercial sector (5–15 Tons of cooling).

• Benefit: It bridges the gap between residential inverters and heavy industrial drives. It provides a cost-effective yet powerful solution for light-commercial rooftop units, VRF systems, and large heat pumps.

2. Superior Power Quality (Grid Friendly)

• Advantage: Features an advanced Active PFC (Power Factor Correction) circuit.

• Benefit: It maintains a power factor near 0.99, meaning almost no energy is wasted as reactive power. This is crucial for commercial buildings to avoid “power factor penalties” from utility companies and ensures the electrical infrastructure stays cool and efficient.

3. Intelligent Diagnostics & Protection

• Advantage: Advanced “black box” logging and real-time monitoring of over 20 parameters (voltage, current, temperature, torque, etc.).

• Benefit: Dramatically reduces troubleshooting time. If a compressor fails or the grid fluctuates, the VSD2001 identifies exactly what happened, protecting the expensive compressor from damage and giving technicians a clear diagnostic path.

4. High Power Density

• Advantage: One of the most compact designs in its power class.

• Benefit: It allows manufacturers to pack more cooling/heating capacity into a smaller outdoor cabinet. This is a major selling point for modern commercial units where roof or ground space is at a premium.
