Arihant systems & electricals deals in a number of products primarily associated with industrial electrical protection and control and industrial automation. These range from industrial fuses, active components such as thyristors, igbts and other semi-conductor devices, passive components such as thermistors, ferrite cores, etc., and automation and control systems and products such as plcs, ac/dc drives, rotary encoders, operator interfaces, scada mmi, proximity switches, etc. The f1500-g series of frequency inverter is the latest general-purpose drive, the system function is enriched and the anti-jamming capacity and maneuverability is improved too. F1500-g series of frequency inverter is a kind of high quality, multifunction, low-noise and large - torque general-purpose frequency inverter that can meet wide range of application. Main functions: special built-in pi adjuster of closed-loop control; controlled by keypad, 485 communication control box, pc and plc, and 125 inverters can be operated at the same time; linear, square curve type and user-defined type of torque-compensation available, adapted to many kinds of loading mode; jogging speed control, external analog signal speed control, multistage speed-control and timing speed control, pc or plc speed control; current and voltage stalling adjustment provided; standard two-wire type and three-wire type of terminal control for more flexibility; user-defined analog input voltage signal/current signal all available, compound speed control and channel switch between single and double realizable; and with the blinking display of present frequency, running frequency can be easily set before running, especially with analog speed control.
