Description
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
Parameter Details
Input Voltage Single-phase 220V or three-phase 380V ±15% (50/60Hz)
Output Frequency 0-400Hz (adjustable via keypad/remote control)
Control Modes V/F, Sensorless Vector Control (SVC), Torque Control
Enclosure Rating IP20 (indoor) or IP55 (outdoor/dusty environments)
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.
