Variable Speed Induction Motor Drive Kit

This new Variable Speed Drive (VSD) significantly improves on the previous Silicon Chip design. It's more compact, lighter, better cooled, and more efficient. It has better safety margins (making it more robust) and some new features. Take full control of your induction motor with the VSD —a compact, efficient, and powerful speed controller for single-phase and three-phase motors up to 1.5kW (2HP). Designed with cutting-edge technology, this unit is smaller, lighter, and more efficient than previous models, thanks to a compact tunnel heatsink, active cooling, and modern AC/DC converters (featured in the November '24 issue of Silicon Chip Magazine).

Features

• Can drive single-phase shaded pole or PSC motors up to 1.5kW
• Can drive three-phase 230V induction motors up to 1.5kW
• Speed range: 1% to 100% of full speed in 0.5% steps
• Runs from a standard 10A GPO
• Inbuilt mains EMI/RFI filter
• Robust inrush current limiting
• Higher efficiency than our previous design
• Fan-based cooling for critical components
• Uses standard, discrete IGBTs for switching
• Compact and lightweight
• Over-current and over-temperature shutdown
• Pool pump mode
• Three-phase motors can be reversed at any time (they will slow down, stop, reverse and speed back up)
• Adjustable speed ramp rate
• Internal or external controls for speed, on/off and emergency stop
• Relay outputs that switch when the motor is up to speed or on a fault
