Feature: 1. Simple Operation: The frequency converter adopts man machine interaction and ergonomic design, which is simple and clear, with one key operation and one key stop function. 2. Fast Heat Dissipation: The cooling fan has strong wind power, the large silent fan has good effect, and the fine craftsmanship is conducive to rapid heat dissipation. 3. Excellent Configuration: The inverter has a faster microprocessor, a new design of the main control board, high quality components, stable and durable, and has a longer service life。 4. Complete Motor Protection: The inverter has 9 protection measures, namely overload, overheat, overvoltage, undervoltage, overcurrent, phase loss, grounding, short circuit, stall and other protections. 5. Wide Application: After the frequency converter is optimized, it has built in PID algorithm and precise torsion vector control, which is widely used in constant pressure water supply, wind pressure and constant pressure control, etc. Specification: Item Type: Frequency Converter Material: ABS Model: SKI70-0D75G-4 Power (Output): 0.75KW Input: AC 3PH 380V±15% 3.4A 47Hz-63Hz Output: AC 3PH 0V-380V 2.1A 0Hz-400Hz.
