45KW 55KW Three Phase Pump Frequency Inverter 440V VFD

45KW 55KW 3 Phase Variable Frequency Drive 220V/380V/440V VFD

Description of frequency converter

Inverters of the ST310 series are high-performance inverters designed on a vector control and torque control
core technology platform. VF control functions are more suitable for high-end control requirements, since they
provide more precise control. In the operation panel, the adjustment knob has a more precise stroke and a
narrow adjustment range. A modular hardware and software solution can address the requirements of high-end
industries such as jack-ups, lifting systems, paper factories, chemical fiber mills, elevators, rolling mills, and
packaging facilities.

Hardware interface of frequency converter
1. There are two analog inputs (AI1, AI2), current (0-20mA), and voltage (0-10V).
2. An analog output consists of two outputs (0-20mA), voltage (0-10V), and current (0-20mA).
3. X1, X2, X3, X4, X5, X6) for switch inputs
4. The high-speed pulse input DI, and the high-speed pulse output Y1, are included.
5. There is one 24V output power terminal
6. Supports the modBUS protocol and the RTU mode for communication on port 485.
