Description

● Excellent Control Performance
Adopting PG-free vector control mode, excellent control performance

Excellent vector control performance

Excellent motor drive performance

Excellent high-frequency running performance

● Optimized Structure Design
Optimized spare utilization, models (≥18.5kW) is much smaller than existing inverters

Mini design for inverters (≤ 2.2kW), abreast installation of multiple inverters, reducing installation space

Flexible installation ways

● Multi-function and easy to use
DC reactors are built-in inverters ≥18.5kW

The braking unit is built-in and standard for inverters ≤37kW but optional for inverters of 45-110kW

Inverters (380V; ≥4kw) support the DC bus sharing solution

Support of external keypad
GD20 series inverters can be configured with LED keypad which has the data copy function to upload or download the parameters.

● Diverse Application Requirements
Simple PLC, multi-speed control, built-in PID, torque control, multi-point V/F curve, multiple braking methods, instantaneous power failure without stopping, etc.

● Applications
Vector control platform products, powerful, excellent performance, can be widely used in small and medium power applications, such as food machinery, plastic machinery, ceramic equipment, petroleum machinery, cable machinery, air compressors, machine tools, woodworking machinery, textile machinery, printing and packaging equipment, chemical equipment, environmental protection equipment, transportation equipment, etc.
