Features Simple Operation: The frequency converter is designed with human-computer interaction and ergonomics, which is simple and clear. The display and buttons of the product can let users get started quickly and operate with one key. Fast Heat Dissipation: The cooling fan has strong wind force, and the large silent fan has good effect. The fine process is conducive to rapid heat dissipation. There is enough cooling space between each component, and the product shell is designed with multiple holes. Excellent Configuration: the inverter has a faster microprocessor, a newly designed main control board, high-quality components, which are stable, durable and have a longer service life. Complete Motor Protection: The inverter has 9 kinds of protection measures, namely overload, overheating, overvoltage, undervoltage, overcurrent, phase loss, grounding, short circuit, stall, etc. Widely Used: After optimization, the inverter has built-in PID algorithm and precise torque vector control, which are widely used in constant pressure water supply, wind pressure and constant pressure control.
