Working Principle

• Rectifier unit converts input AC power into DC bus voltage; IGBT inverter unit converts DC‑bus into adjustable‑frequency adjustable‑amplitude three‑phase AC output for asynchronous‑motor driving
• Control‑unit executes V/F algorithm according to set‑point signal to adjust output voltage‑frequency characteristic, realizes motor‑speed regulation
• Hardware‑protection circuit monitors voltage, current and temperature signals, triggers output shutdown upon fault‑condition detection

Installation Requirements

• Mount inside IP20‑rated control cabinet, vertical installation orientation
