Variateur de vitesse VFD Heavy Duty VFD 0.4-5.5KW Single Three Phase Motor Speed Controller 0-400Hz Detachable Control Panel

Key Features

• True Vector Control Performance:

Sensorless vector control algorithm — enables precise speed regulation (±0.5% at rated load);

Torque response time ≤10 ms — suitable for high-dynamic applications (e.g., CNC spindles, conveyors);

Speed range: 0.1 Hz to 500 Hz (adjustable via keypad or external analog signal);

Motor compatibility: Induction motors (IM) and permanent magnet synchronous motors (PMSM).

• Flexible Input/Output Configuration:

Input voltage options:

Single-phase 220 V AC (for EV4300 models: 2.2 kW, 5.1 A max);

Three-phase 380 V AC (for all EV8100 models: 4 kW to 30 kW, 9 A to 60 A);

Output voltage: Fixed 220 V or 380 V (matches input configuration);

Output frequency: 0–500 Hz, adjustable in 0.01 Hz steps;

Control modes: V/F control, open-loop vector, closed-loop vector (with encoder feedback option).

• Robust Hardware Design:

Digital keypad panel: 4-digit LED display + 6-function keys (RUN, STOP, PRG, MF.K, ▲, ▼);

Cooling system: Forced-air cooling with dual fans (on models ≥7.5 kW) — ensures stable operation at 40°C ambient;

Protection rating: IP20 — suitable for indoor cabinet mounting only;

Mounting: DIN rail (small models) or panel screw holes (large models) — flexible installation;

Weight & size:

EV4300 (2.2 kW): 1.15 kg, 10.6×15.4×16 cm;

EV8100 (30 kW): 16.75 kg, 28.7×24.7×46.6 cm;

Terminals: Screw-type, 5.08 mm pitch, UL94 V-0 flame-retardant PA66 — prevents arcing.

• Comprehensive Protection System:

Overvoltage (OVP): Shuts down if DC bus >750 V;

Undervoltage (UVP): Alarms and stops if DC bus <200 V;

Overcurrent (OCP): Cuts output if phase current >150% of rated for >10 ms;

Short Circuit (SCP): Immediate shutdown on output short;

Overload (OLP): Thermal model-based protection — limits torque to prevent motor burnout;

Overheat (OTP): Activates at heatsink temperature >90°C;

Ground Fault Detection: Monitors leakage current >30 mA.

• Certifications & Compliance:

CE certified — complies with EMC Directive 2014/30/EU and Low Voltage Directive 2014/35/EU;

RoHS compliant — lead-free, cadmium-free, mercury-free;

Safety standard: IEC 61800-5-1 (adjustable speed electrical power drive systems);

Made in China – fully assembled and tested in ISO 9001-certified facility.

CNC Machinery: Spindle control, feed axis drives, and tool changers requiring precise speed/torque.

Conveyor Systems: Belt and roller conveyors with variable speed demand for sorting and packaging lines.

Pump & Fan Control: Centrifugal pumps, HVAC fans, and water treatment systems for energy savings.

Textile & Printing Equipment: Yarn winding machines, printing presses, and cutting systems.

Renewable Energy: Generator speed regulation in small wind turbines and hydroelectric systems.
