INVT GD290-7R5G/011P-4 Frequency converter, multi-pump control, Modbus communication

1.Product Overview

INVT GD290-7R5G/011P-4 is an inverter from YINGWEI-TENG's GD290 series, a low-voltage multi-functional universal inverter. It is of the G type (constant torque) with a power of 7.5kW, and the P type (variable torque) with a power of 11kW. It operates on three-phase 380–480V, featuring a compact book-shaped structure. It is designed for mid-to-high-end universal drive scenarios, emphasizing high-performance vector control + high reliability + energy saving. It is suitable for equipment such as fans, pumps, conveyors, and mixers.

2. Product Advantages
