Shenzhen MaoTeWang Electronic Technology Co., Ltd.

VTS30 Series Universal Variable Speed AC Drives

Product introduction

Features

Compact Structure
Boasts outstanding load capacity. The inverter can operate stably without tripping under arbitrary acceleration/deceleration time and impulse load conditions.
Multiple Optional Operation Panels
A variety of keypad options are available:
Chinese & English LCD panel, Chinese & English LCD panel with built-in potentiometer, and LED operation panel.
Multiple Control Modes Supported
It supports V/F control, asynchronous current vector control, asynchronous voltage vector control, and open-loop synchronous motor control.
Customizable Design
Models ranging from 355kW to 500kW adopt cabinet-type structure. The incoming and outgoing wiring modes can be customized according to customer requirements and on-site working conditions.
