Description: This Variable Frequency Drive is made of high quality shell material, heat resistant and flame retardant. Humanized keyboard design, easy to operate. Digital display screen makes it convenient to read clearly.   Features: This VFD uses unique control method to realize high torque, high precision 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. Over current, over voltage, over heat, overload, Fast start and stop response, large torque at low speed.   Specification: Application range: Universal Power supply phrase: Single phase / 3-phase Rated current: 2-14A Rated voltage: AC 220V (single phase) / AC 380V (3-phase) Rated power: 0.5KW, 0.7KW, 1.5KW, 2.2KW, 3.0KW Motor Filter: No DC power supply: Current type Control method: V/F open loop Output voltage adjustable method: PWM control   Package List: 1 x Variable Frequency Drive 1 x 1 meter extension cord
