Delta VFD MS300 0.4kW 0.5HP 1-Phase to 3-Phase AC Drive - 2A8MS21ANSAA
The Delta VFD MS300 (2A8MS21ANSAA) is an ultra-compact vector control drive designed for small-scale industrial applications requiring precise motor regulation from a single-phase 230V power supply. This 0.4kW (400W) drive is the perfect solution for micro-CNC routers, small conveyor belts, and cooling fans where space is at an absolute premium. Despite its small footprint, it supports both Induction Motors (IM) and Permanent Magnet (PM) motors and features built-in PLC functionality (2k steps) and a Safe Torque Off (STO) safety circuit. With high-speed output capabilities up to 599 Hz and a built-in USB port for rapid parameter cloning, the MS300 delivers stable torque and energy efficiency for micro-automation systems.
- 1-Phase 230V Input / 3-Phase 230V Output
- High-efficiency Open-loop and Vector control
- Built-in PLC logic (2000 steps)
- Integrated USB port for parameter backup and tuning
- Safe Torque Off (STO) safety compliance
- Support for IM and PM motor types

Technical FAQ & Operational Guide
Can I run a standard 3-phase motor with this single-phase VFD?
Yes, provided the motor is rated for 230V 3-phase (usually by wiring it in Delta configuration). This VFD converts your 230V single-phase wall power into 230V 3-phase output.
Does this micro-drive require a cooling fan?
At 0.4kW, this model often utilizes high-efficiency natural cooling through its integrated heat sink, though proper cabinet ventilation is always recommended.
Can it be used for high-speed spindles?
Yes, it supports an output frequency up to 599 Hz, which is ideal for small, high-speed spindles used in micro-CNC and engraving machines.
