Feature: 1. CLEAR DISPLAY: The vector inverter has dual digital tube display control panel, man machine interaction, fast running and stopping, convenient in operation. 2. GOOD COOLING: The use of silent cooling fan, strong wind, is conducive to the rapid dispersal of heat to the fins, ensuring long term operation of the machine. 3. EXCELLENT PARTS: Using faster microprocessor, new design of the main control board, with excellent components, the frequency converter is efficient and reliable. 4. MOTOR PROTECTION: With overload, overheat, overvoltage, undervoltage, overcurrent, phase loss, grounding, short circuit, stall protection, to better protect the motor. 5. WIDE APPLICATION: With optimized built in PID algorithm and precise torsion vector control, widely used in constant pressure water supply, wind pressure control, etc. Specification: Item Type: Frequency Converter Material: ABS Output Power: 5.5KW Input: AC 3PH 380V±15% 14.6A 47Hz-63Hz Output: AC 3PH 0V-380V 13A 0Hz-400Hz. Package List: 1 x Frequency Converter1 x User Manual Note: 1. Motors with capacitors cannot use this inverter for speed regulation! 2. The inverter cannot be used as a power source.3. When installing and using, please carry out under professional guidance, pay attention to the safety of electricity use, and do a good job of safety protection.
