1\Three kinds of speed control types: Vector control without PG, vector control with PG, V/F control;
2\Reach 180% low frequency torque output, torque control accuracy: ± 5%;
3\Speed accuracy of vector control with PG: 0.1%, range of speed regulation: 1: 1000;
4\Inverter 18.5KW to 90KW, internally installed direct current reactor, increases the output of power factors to enhance the efficiency and stability of complete appliance, and eliminates the influence of incoming ultraharmonics on inverters to reduce interference;
5\All models of 1.5KW~15KW inverters with a built-in brake unit allowing quick stops to directly brake resistors;
6\Various expansion cards: Tension cards, water supply cards, IO expansion cards, communication cards and PG cards;
7\Rotational speed trace and restart facility: Shockless and smoothly start the running motor;
Guangzhou Zhufeng Electric Co. Ltd is founded on May 28th of 2004, which is a privately-owned hi-tech enterprise specializing in researching, manufacting low-voltage\full power inverter. The products have been widely used in industries of thermal power generation\metallurgy\oil and mining\chemical\machinery\water supply in cities\plastics\cement\paper-making and pharmacy.
The general type inverter that we produce can realize driving and speed regulation to all kinds of low-voltage motor. And the special inverter for fans&pumps is used in speed regulation, energy-saving, soft-start, and intelligent control of load in fans, pumps, air compressor, and comprehesive benefits is significant.
