Structural Features
Integrated vertical cabinet structure, built-in cooling fan, front panel operation display area, bottom terminal wiring area, internal modular power unit, metal frame reinforcement structure.
Functional Characteristics
Realize stepless speed regulation of three-phase asynchronous motor, motor soft start and soft stop, overload, overcurrent, overvoltage, undervoltage and phase loss protection; support multiple control modes and communication connection.
Working Principle
Convert industrial AC power into DC power through rectifier module, then invert DC power into AC power with adjustable frequency and voltage through inverter module; change motor rotating speed by adjusting output frequency, and realize motor operation protection through built-in detection circuit.
Material Composition
Shell: Thickened cold-rolled steel sheet with electrostatic spraying; Internal power module: IGBT power module, rectifier bridge; Heat dissipation part: Aluminum alloy heat sink, axial flow cooling fan; Control part: Industrial control mainboard, capacitor group.
Advantages & Highlights

Applicable Industries
Material handling equipment, conveyor, lifting machinery, food processing machinery, packaging machinery, chemical industry equipment, water pump and fan energy-saving transformation.
Installation Requirements
- Install vertically on flat wall or control cabinet, tilt angle not exceeding 3°.
- Reserve upper and lower ventilation gaps of no less than 150 mm for heat dissipation.
- Power line and control line are wired separately, use specified cable specification.
- Reliable grounding is mandatory, grounding resistance ≤ 4 Ω.
Usage Notes
- Do not run beyond rated current and rated power for a long time.
- Cut off main power before opening the shell for maintenance.
- Keep the internal heat sink and fan clean to prevent dust blockage.
- Set parameters strictly according to motor nameplate data.
