Feature: 1. PORTABLE DESIGN: The inverter has a clear control panel, dual digital tube display, man machine interaction, a touch run and stop, is convenient and fast in operation. 2. GOOD COOLING: Large silent cooling fan with strong wind, which is conducive to the rapid dispersal of heat to the fins, ensuring long term operation of the inverter. 3. HIGH PERFORMANCE: Using faster microprocessor and excellent components, new design of the main control board, the frequency converter is efficient and stable. 4. CIRCUIT PROTECTION: With overload, overheat, overvoltage, undervoltage, overcurrent, phase loss, grounding, short circuit, stall protection functions, with safe operation. 5. WIDE APPLICATION: 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: 7.5KW Input: AC 3PH 380V±15% 20.5A 47Hz-63Hz Output: AC 3PH 0V-380V 17A 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.
