Product Overview

The CY-GP series intelligent high-voltage variable frequency speed control system adopts power unit series multi-level technology, directly outputting 6KV and 10KV voltages, and is a high high voltage source type frequency converter. The company's design goals are high reliability, easy operation, and high performance, meeting the urgent needs of users for energy-saving speed regulation of fans and pumps, and improving production processes; In order to minimize the construction period of installation and renovation of the high-voltage variable frequency speed regulation system, the system adopts an integrated design concept, including all components and internal wiring such as transformer cabinet, power cabinet, control cabinet, (high-voltage switch cabinet or bypass cabinet optional). Users only need to connect high-voltage input, high-voltage output, low-voltage control power supply, and control signal line.

In order to meet the needs of renovation projects and reduce the investment in new projects, each functional component of the CY-GP series high-voltage variable frequency speed regulation system can be installed step by step, ensuring that the high-voltage variable frequency speed regulation system will not encounter accidents during transportation and installation.
