INVT inverter GD300-02-037G-4 protection grade IP20

Introduction:INVT GD300-02-037G-4, GD300-02 series through-wall inverter is a wall-piercing special machine, designed and developed for the secondary pollution of cotton wool, dust, oil and other foreign bodies to the inverter, which improves the reliability of the product and the adaptability of the environment. The product adopts high-performance vector control technology, has good dynamic characteristics, and has built-in power-off synchronization, fault synchronization and other controls for the characteristics of the textile industry, which can realize safe shutdown under abnormal working conditions.

INVT inverter GD300-02-037G-4 protection grade IP20

Features:

The heat dissipation system and the electrical system are relatively separated, and the cotton wool, oil stains, etc. are effectively dealt with

Long-term, reliable operation at an ambient temperature of 50°C

Powerful drive performance, compatible with synchronous and asynchronous motors

The full series supports common bus schemes
