1. Model Code Meaning

• 3003: Size / power = 11 kW（10 A）

• 403: 3×AC 380–500 V, no integrated EMC filter

• 4: 4‑quadrant（regenerative braking, can feed energy back）

• 00: Standard firmware, no special options

2. Key Technical Data

• Input: 3×AC 380–500 V, 50/60 Hz

• Output: 3×0–400 V, 0–150 Hz, 10 A

• Rated power: 11 kW（motor‑matched）

• Control: V/f, Sensorless Vector (VFC)

• Overload: 125% continuous；150% / 60 s

• I/O: 6DI / 2DO / 1 relay；2AI / 2AO

• Protection: Overcurrent, overvoltage, undervoltage, overtemperature, earth fault

• Enclosure: IP20

• Ambient temp: 0 °C ~ +45 °C（derate above 40 °C）

• Weight: ≈ 10 kg

3. Features（vs 3003-403-1-00）

• ✅ 4‑quadrant + regenerative braking（critical for hoists, cranes, downhill conveyors）

• ✅ Energy recovery: Braking energy fed back to grid, saves energy

• ✅ Dynamic performance: Faster deceleration, lower heat, no external brake resistor needed

• ✅ Same compact MOVITRAC 3000 platform, same I/O and options

4. Typical Applications

• 11 kW three‑phase motors（asynchronous）SEW-EURODRIVE

• Cranes, hoists, winches（vertical/heavy loads）

• Conveyors（downhill, high inertia, frequent stop/start）

• Fans/pumps requiring fast stop or regenerative loads

5. Quick Comparison（3003 series）

• 3003-403-4-00: 4‑quadrant, regen, dynamic loads, higher cost

• 3003-403-1-00: 1‑quadrant, no regen, standard fans/pumps, lower cost
