Easy Integration with Your System for Advanced Control
Integrating RIGID’s drive board (PCB) and optional display panel into your system is simple - perfect for users who need advanced functions or want to control the compressor using their own software.
The motor drive board enables variable-speed operation, allowing you to adjust the cooling capacity by changing the compressor speed. It accepts a 0–5V DC analog control signal to regulate speed precisely.
- Minimum speed: 2,000 RPM (when control voltage is 0.7V or lower)
- Maximum speed: 6,000 RPM (at 4.5V or higher)
- Between 0.7V and 4.5V, the speed control is linear and can be calculated using the formula: S = 1132 × V + 1408
- Where S = compressor speed in RPM, and V = control voltage in VDC.
This flexible setup gives you smooth and reliable control, making it easy to customize cooling performance based on your specific application requirements.
