XC700 Intelligent VFD

Intelligent VFD is a device that optimizes energy efficiency by automatically adjusting motor speed and is widely used in industrial control systems.

Advantages

Precise Control
The XC700 utilizes Hybrid Vector Control (SVC), providing ±0.01% frequency control accuracy without relying on speed sensors.

Powerful Load Capacity
Supporting an overload capacity of 150% of the rated current, it can operate stably for up to 1 minute under high load or sudden operating conditions.

Flexible Control Modes
Supports three control modes: V/F, SVC, and VC, with intelligent switching based on different application scenarios.

Efficient Energy Management
The XC700 features built-in energy regeneration and energy-saving control functions, automatically adjusting power output in different operating modes.

Multiple Protection Mechanisms
Comprehensive overload, overvoltage, overtemperature, and other protection features make it suitable for high-risk industrial applications.
