LX3300 11 kW Three-Phase 380 V Vector Control Var | RFQ Sourcing Details

Product overview The LX3300-011G-4 is an 11 kW variable frequency drive designed for controlling AC motors on a three-phase 380 V supply. Its listed ratings are 17 kVA power capacity, 26 A input current, and 25 A output current. The model provides 0–380 V output and a listed output-frequency range of 0–400 Hz.

Overall dimensions are 320 × 205 × 198 mm, with 190 × 305 mm mounting-hole spacing and 6 mm mounting holes. Control and operating functions Supported control modes include sensorless open-loop vector control, closed-loop vector control, and V/F control.

The series specification lists starting torque of 150% at 0.5 Hz in sensorless vector mode and 180% at 0 Hz in closed-loop vector mode.

Other listed functions include motor parameter autotuning, automatic and manual torque boost, straight-line or S-curve acceleration and deceleration, DC injection braking, automatic voltage regulation, torque limiting, fast current limiting, and a built-in PID controller.

The built-in PLC or control terminals can provide up to 16-speed operation. Two motor-parameter sets support switching between two motors. Run commands can be Frequency references can use digital settings, analog voltage, analog current, pulse input, or serial communication.

Interfaces and protection Standard inputs include five digital input terminals, including one supporting high-speed pulse input up to 100 k. Hz, plus two analog inputs. Standard outputs include a high-speed pulse output, one digital output, one relay output, and one analog output configurable for 0–20 mA or 0–10 V.

The listed communication options include Modbus, PROFIBUS-DP, CANlink, and CANopen;buyers should confirm which communication hardware is standard and which requires an optional card.

Listed protection functions cover overcurrent, overvoltage, undervoltage, overheating, phase loss, overload, short-circuit detection, and braking-circuit-related faults. A built-in braking unit is listed for series models from 0.4 to 37 kW.

This 11 kW model uses the standard membrane keypad specified for units rated at 15 kW or below, while an LCD keypad is optional. Operating conditions The stated environment is indoor use away from direct sunlight, dust, corrosive gas, oil mist, water vapor, and salinity.

Listed limits are below 1,000 m altitude, -10°C to +40°C without the stated high-temperature derating, relative humidity below 95% without condensation, and vibration below 5.9 m/s². Operation from 40°C to 50°C requires derating. Storage temperature is listed as -20°C to +60°C.

Procurement confirmation Before ordering, confirm the motor nameplate voltage, rated current, load type, required speed and torque range, braking duty, enclosure or cabinet arrangement, and whether open-loop or encoder-based closed-loop control is required.

Also verify the exact input-voltage configuration, because the series data includes both 220–240 V and 380–440 V variants while this model is identified as the three-phase 380 V version.

Confirm required communication and encoder cards, keypad type, I/O expansion, temperature-sensor interface, water-treatment control requirements, certification documents applicable to the delivered unit, and any customization scope.

Packaging is listed as a carton with plywood packing;confirm final packing, included accessories, delivery schedule, inspection requirements, and after-sales terms for the intended order.
