INVT inverter GD350-13-055G-4 protection grade IP20

Features:

All-round adaptation: integrated beam type, tower type, direct drive screw pump and other types of pumping unit special control functions.

Energy saving and efficiency increase: reduce reactive power according to load changes in real time, saving more than 20% of electric energy compared with the previous generation of products. The up/down speed can be set separately to make more strokes in the same time.

Mine monitoring: Added special functions for pumping units, such as pumping balance rate detection and dynamic fluid level detection, to monitor the status of the well and mine in real time and make automatic adjustments.

Automatic drainage: It can enter the sleep and wake-up state through external signals or time settings, and can perform low-power swing actions in the best balance position.

Strong expansion capability: support 3 expansion interfaces, support various types of expansion cards (IO expansion card, communication card, PG card, PLC card), support any card slot installation.

Standard braking unit: 380V voltage level products are equipped with built-in braking unit as standard, which reduces customer cost and installation volume.

Standard STO function: the application is more secure and reliable.

Built-in DC reactor: 380V 18.5-75kW is equipped with built-in DC reactor as standard, with high power factor and reduced interference to the grid environment.
