Features: This VFD uses unique control method to realize high moment of force, high accuracy and wide speed regulating range driving, with high performance. It has good anti-trip performance and ability to adapt to rough power, temperature, humidity and dust interference, greatly improved stability. By optimizing PWM control technology and electromagnetic compatibility, it satisfies users' requirement of low noise, low electromagnetic interference. Simple to operate and wire, connect to wires by screw terminals which are more convenient. Designed with large heat sink for better heat dissipation. Specifications: Model: AT3-0750X Power Source Phase: Three-phase Rated Voltage: Three-phase AC380V Power Supply Voltage: Low voltage Suitable Motor Power: 0.75kW Filter: Built-in filter DC Power Supply Type: Voltage type Control Method: V/F closed loop Output Voltage Adjusting Method: PWM control Rated Current: 3A Protection: Over-current, over-voltage, over-heat, under-voltage, short circuit protection Max. Output Frequency: 400Hz Size: Approx. 18*12.5*12.5cm/7.1*4.9*4.9in Weight: 1.3kg(approx.) Note: 1. When adjusting parameter, the VFD must stop working, otherwise it will not be able to save parameter setting. 2. Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
