Power Conversion & Drive
Topology: IGBT three-level NPC structure delivers an output waveform close to pure sine with low harmonic distortion (THDi < 5%).
Input Voltage: 3.3 kV / 6 kV / 6.6 kV (±10%), supporting both 50 Hz and 60 Hz grids.
Output Voltage: Same level as input voltage; adjustable output frequency range 0.1–120 Hz.
Overload Capacity: 150% of rated current for 60 s and 200% of rated current for 3 s, fully compliant with IEEE 1566.
Control Modes
Open-loop V/f Control: For simple speed regulation in fans, pumps, etc.
Closed-loop Vector Control: Sensorless vector control (DTC) with < 5 ms dynamic response for high-precision loads such as winches and extruders.
Communication Interfaces
Protocols: Modbus TCP/IP, Profibus DP, Profinet and other mainstream standards.
System Integration: Fully compatible with DCS/SCADA systems.
Network Redundancy: Optional dual Ethernet ports supporting ring-network redundancy (MRP) with < 200 ms communication recovery.
Safety & Protection
Overcurrent / overvoltage / undervoltage protection with automatic output cut-off and alarm.
Ground-fault detection < 10 ms to prevent motor insulation breakdown.
High-speed start capability for smooth synchronization with freely rotating motors to avoid mechanical shock.
Reliability Design
Power Unit Redundancy: N+1 configuration (e.g., 5-unit operation + 1-unit hot standby). Automatic bypass and system derating maintain operation after single-unit failure.
Fault Self-diagnosis: Real-time monitoring of IGBT temperature, DC bus voltage, capacitor life; fault localization accuracy down to the unit level.
Environmental Adaptability
Operating temperature: –20 °C to +50 °C (with forced air cooling).
Humidity: 5–95% (non-condensing).
Protection rating: IP42 (cabinet-mounted).
Vibration/shock: Meets IEC 60068-2 standards for harsh industrial environments.
Application Areas
Ideal for speed regulation of large fans, pumps, compressors, winches and similar high-power loads across oil & gas, metallurgy, mining, power generation, water treatment and other heavy industries.
