Material Composition:
- Enclosure: Galvanized steel, powder-coated (RAL 7035)
- Heat sink: Extruded aluminum (6063-T5)
- Power module: IGBT (650 V, 150 A) – Fuji/Mitsubishi
- PCB: FR-4, conformal coated, 2-layer + 4-layer power board
- Fan: Ball bearing, IP55 rated
- Terminal block: Phoenix Contact, UL listed

Working Principle:
AC input → diode bridge rectifier → DC bus (capacitors) → IGBT inverter (PWM) → 3-phase AC output to motor. V/F ratio controls motor speed. In vector mode, drive estimates motor flux/torque for precise speed control.
Advantages:
- 100 HP in compact footprint
- Sensorless vector for pump/fan applications without encoder
- Built-in dynamic braking eliminates external resistor
- Multiple communication protocols for BMS integration
Applicable Industries:
- Pumping stations (water/wastewater)
- HVAC (chillers, cooling towers)
- Conveyor systems
- Compressors
- Mining and metals
Installation Requirements:
- Mount on vertical surface with adequate clearance (min 200 mm above, 100 mm below)
- Input cable: 4-core, 70 mm² Cu (for 100 HP)
- Output cable: 4-core, 70 mm² Cu, shielded (max 50 m)
- Ground cable: same size as power cable
- Torque terminals: 12 N·m (power), 2.5 N·m (control)
Usage Notes:
- Always install input reactor (5% impedance) for drives above 50 HP
- Do not operate motor above base frequency (60 Hz) without flux weakening
- Set motor nameplate data (voltage, current, FLA, RPM) before first start
- Derate output current 1% per °C above 40°C ambient
