Frequently Asked Questions

Q: What power tools is this 230V soft start module compatible with?

A: This soft start drive module is designed for a wide range of 230V AC electric power tools, including angle grinders, cutting machines, slotting saws, and aluminum-working machines. Its compact 36×20mm or 36×22mm form factor allows built-in installation into most standard tool handles and housings.

Q: What are the three start modes and when should I use each one?

A: The module offers three selectable startup modes: Current Limit Start (caps the inrush current for sensitive motors), Voltage Ramp Start (gradually increases voltage for a smooth acceleration curve), and Smooth & Stable Start (provides the most gradual, consistent startup for general use). Choose based on your tool's motor type and your preferred startup behavior.

Q: What is the maximum current rating for this soft start module?

A: The module supports a maximum current output of 20A (with a 12A option also available depending on the variant), making it suitable for most standard 230V power tools used in home workshops and light professional settings.

Q: Is installation of the soft start module difficult?

A: Installation is straightforward for anyone with basic electrical DIY knowledge. The module is designed to fit into existing tool handles and shells without major modification. Always ensure the tool is unplugged and fully de-energised before installation, and follow all relevant local electrical safety guidelines.
