Industrial Servo Inverter VFD: 0-400Hz Adjustable Speed, Full Protection For Pumps & Fans


1. Core Features

  • Wide Speed Range (0-400Hz)
    • Enables precise speed control for low-speed (e.g., gentle fan rotation) and high-speed (e.g., centrifugal pump acceleration) applications.
    • Supports soft start/stop to reduce mechanical stress and energy consumption.
  • Full Motor Protection Suite
    • Overload Protection: Automatically trips if current exceeds rated capacity (e.g., 150% overload for 1 minute).
    • Overvoltage/Undervoltage Protection: Safeguards against voltage surges (e.g., lightning strikes) or drops (e.g., grid instability).
    • Overheating Protection: Monitors IGBT temperature and shuts down if thermal limits are exceeded.
    • Phase Loss Protection: Detects missing phases (e.g., L1, L2, L3) and prevents motor burnout.
    • Ground Fault Protection: Isolates the system during insulation failures to prevent electric shocks.
  • Optimized for Pumps & Fans
    • PID Control: Adjusts motor speed in real-time to maintain constant pressure (pumps) or airflow (fans), reducing energy waste by up to 30%.
    • Sleep/Wake Function: Automatically powers down pumps/fans during idle periods (e.g., nighttime) and restarts when demand resumes.
    • Dry Run Protection: For pumps, detects low liquid levels and stops the motor to prevent damage.

2. Technical Specifications

Communication RS485 (Modbus RTU), optional Profibus-DP/EtherCAT
Display LED/LCD screen showing frequency, current, fault codes, and operating status


3. Key Applications

  • Centrifugal Pumps
    • Challenge: Throttling valves waste energy when reducing flow.
    • Solution: VFD adjusts pump speed to match demand, cutting power use by 40% (e.g., HVAC cooling towers).
  • Axial Flow Fans
    • Challenge: Fixed-speed fans cause noisy operation and excessive airflow.
    • Solution: VFD ramps down fan speed during low-demand periods (e.g., nighttime ventilation), reducing noise by 10dB.
  • Water Treatment Systems
    • Challenge: Manual control leads to inconsistent chemical dosing.
    • Solution: VFD integrates with flow meters and PID loops to maintain precise dosing rates (e.g., chlorine injection pumps).

4. FAQs

  • Q: Can this VFD handle single-phase motors?
    A: No, it requires three-phase motors. For single-phase applications, use a phase converter or a dedicated single-phase VFD.

  • Q: How often should I perform maintenance?
    A: Check cooling fans and heat sinks every 6 months. Replace capacitors every 5–7 years.

  • Q: Is IP55 necessary for indoor use?
    A: Not required, but IP55 models resist dust and accidental water splashes, extending lifespan in workshops.
