H900 series high performance current vector inverter Type Advanced Module IGBT Power range 0.75~2.2kW single phase 220V 0.75~630kW three phase 380V The H900 series is a software upgrade of the A900 without changing all hardware, and has the following functional highlights: Automatic constant voltage technology: Under the same power conditions, the H series can keep the motor running efficiently and stably; Compared with the A series: the low-frequency torque of the H series is increased by 20%, and the torque response speed is increased by 2 times; H series function code parameter setting range is wider and the functions are richer; With voltage suppression function, H900â??s performance is even more remarkable in scenarios with regenerative energy feedback. Applications: Mainly used in chemical industry, food, textile, plastics, metallurgy, crushers, fans, cold heading machines, CNC lathes and other scenes with large inertia, heavy load and regenerative energy feedback
