Introduction
The document describes the New Serie XC motor control module developed by OESSE s.r.l. for use with external rotor fans. It includes both hardware (HW) and firmware (FW) components, fully developed and customized by OESSE.

Specifications
The module is designed to start and control motor speed by applying a sinusoidal voltage with variable frequency and amplitude. It avoids harmful harmonics through real-time calculations by a Digital Signal Processor (DSP). The module supports both single-phase and three-phase motors with specific voltage and power ratings:

• Model ECS10M: Single-phase 230V, 1000W
• Model ECS23T: Three-phase 400V, 2300W

Operating temperature ranges from -40°C to +70°C, with a protection class of IP 54.

Technical Features
The module uses Pulse Width Modulation (PWM) through six channels controlled by a microcontroller, eliminating the need for a start capacitor. It interfaces externally via input channels for motor speed regulation using:

• 4-20 mA
• 0-10 V
• NTC
• ModBUS serial bus

Efficiency is rated at 95%, starting from 40% of nominal power.

Compliance and Standards
The module complies with several standards, including EN 61800-2, EN 61800-3, EN 61800-5, EN61800-5-2, and CENELEC EN 60335-1.

Conclusion
The New Serie XC motor control module offers advanced features for efficient and harmonic-free motor control, suitable for various motor types and applications.
