7.5kW 220V - 380V Variable Frequency Drive (VFD/VSD) - SU900-7R5G1

VFD 7.5kW SU900-7R5G1 - Single Phase 220V to Three Phase 380V Boost Drive

Model: SU900-7R5G1
Series: SU900 Vector Control Frequency Converter

Motor Power Capacity:
Rated for 7.5kW (approximately 10HP) three-phase 380V motors, with a rated output current of 17A.

Input Supply:
Single-phase 220V AC (±15%), 50/60Hz, suitable for standard residential and commercial electrical supplies.

Output Supply:
Three-phase 380V AC with adjustable voltage and frequency (0-380V). The integrated voltage boost function enables direct operation of 380V motors from a 220V input source.

Frequency Range:
Adjustable from 0 to 400Hz, allowing accurate motor speed control across low and high operating speeds.

Control Methods
V/F Control: Traditional volts-per-hertz control for general applications.
Sensorless Vector Control (SVC): Enhances torque output and speed stability, particularly at low speeds, without requiring an encoder.

Control Operating Features
PID Control Built-In: Supports closed-loop control for applications such as maintaining constant pressure or flow.
Multi-Speed Operation: Programmable stepped speeds via digital input control.
Jog / Inch Mode: Enables precise, short-duration motor movement for setup and maintenance tasks.

Communication
RS485 Interface: Integrated Modbus RTU protocol for straightforward integration into automation systems.

Protection & Reliability: Comprehensive internal protection including overcurrent, overvoltage, undervoltage, motor overload, VFD overheating, short-circuit, and phase-loss protection to ensure safe and dependable operation.

Inputs & Outputs: Multiple programmable analog inputs (0-10V and 4-20mA) for frequency reference, along with configurable digital inputs and outputs for external control signals.

Braking Performance: Includes a built-in braking unit to dissipate regenerative energy during motor deceleration through dynamic braking.

User Interface & Cooling: Features an intuitive digital keypad with a clear LED display for parameter adjustment, real-time operation monitoring, and fault diagnostics. An efficient forced-air cooling system helps maintain stable operating temperatures.

Compliance: Manufactured to meet international standards, including CE, FCC, and RoHS compliance.

Dimensions:
242x125x170mm
