I. Product Overview
GD270-075-4 is a Goodrive270 series inverter specifically designed for fans and pumps. It operates on three-phase 380V, 75kW, and is tailored for second-order law load applications of fans and pumps. It is compatible with both asynchronous and permanent magnet synchronous motors, integrates industry-specific control logic, and is renowned for its high efficiency, reliability, and ease of maintenance. It is widely used in continuous operation scenarios such as municipal, water supply, HVAC, chemical, metallurgical, and power industries.

II. Product Advantages

• ✅ Significantly energy-saving: The new ECO energy-saving algorithm automatically reduces power consumption under light load conditions; supports permanent magnet synchronous motors, achieving a comprehensive energy saving of 20%–40%; sleep/wake function, automatic shutdown for low-load operation at night to reduce consumption.
  ✅ Specialized for fans and pumps, ready to use out of the box: Built-in dual PID, up to 8 multi-pump polling, flexible water pipe filling, cleaning, liquid level / constant pressure control; dedicated protection for frost, condensation, water leakage, fire penetration; simple debugging, no complex programming required.
  ✅ Strong grid adaptability, durable: 380–480V wide voltage range, tolerance for fluctuations ±15%; independent air duct + three-proof paint, dustproof, moisture-proof, heat-resistant; IP20, compliant with 3C3/3S3; long-term stable operation in harsh environments.
  ✅ Flexible expansion, easy integration: Optional built-in DC / output reactor; supports Profinet/Profibus-DP/CANopen/Modbus-TCP; dual I/O card slots; compact book-shaped design, saves space for installation inside the cabinet.
  ✅ User-friendly maintenance: Parameter upload/download, LCD keyboard, fault recording; supports bypass switching of industrial frequency inverters, maintenance without downtime.
