Product overview This threephase inverter, model 310, is a compact and versatile DC to AC drive designed for precise motor control and reliable operation across industrial and commercial applications. It supports input and output configurations suitable for standard 220V systems and offers flexible control, braking, communication, and protection functions. Key specifications Model number: 310 Type: DC/AC Inverters Input voltage: 1phase 220V Output voltage: 3phase 220V Output frequency: 0500HZ Output power range: 0.75 to 4KW Control methods: V/F and vector control Brake module: Yes, builtin brake unit for connecting brake resistance RS485 communication: Yes Size: 3phase 380V Style: 3phase 220V Color: 0.75KW Core functions and advantages Forward, reverse, start and stop can be controlled from the builtin panel or by external terminals for flexible installation and operation. Speed adjustment via onboard potentiometer or external potentiometer lets you tune motor speed precisely for different processes. Builtin brake unit supports connection of a brake resistor for controlled deceleration and load holding. PID function enables closed loop control for tasks such as constant pressure water supply and other automated regulation needs. Multistage run provides preset speed steps for repeatable operation and simplified programming. RS485 serial communication allows integration with PLCs and monitoring systems using common industrial protocols. Vector control delivers improved torque performance and responsive control, with strong lowfrequency performance for demanding loads. Optional external control panel is available separately when remote mounting or extended user interface is required. Overload protection protects the motor and drive against excessive current and prolonged heavy loading. Why this product solves common problems Replaces fixedspeed drives with accurate, adjustable control to save energy and reduce mechanical stress. Builtin brake module and overload protection improve equipment safety and reduce downtime from motor stalls or reversing loads. PID and multistage run functions allow automation of water pressure, speed ramps, and repeated operational sequences without additional controllers. RS485 communication simplifies integration with existing control systems for remote monitoring and centralized control. Performance and compatibility Supports a wide output frequency range up to 500Hz for applications that require abovenormal speed operation or variable frequency testing. Compatible with standard singlephase 220V supply feeding threephase 220V motors, and provided specifications include common 3phase configurations for flexible deployment. Control options V/F and vector accommodate both simple fan and pump control and higherperformance applications requiring tight speed or torque control. Typical applications Constant pressure water supply systems using the PID function to maintain stable pressure across varying demand. Conveyor and material handling systems requiring forward and reverse control, multistage speed steps, and reliable braking. Small machine tools, pumps, and fans where variable speed, overload protection, and RS485 communication improve process control and system integration. Installation and use notes External control panel sold separately if remote operation is needed. Brake resistor must be selected and connected when using the builtin brake unit. Ensure motor and inverter ratings match when selecting units in the 0.75 to 4KW range. This inverter model 310 provides compact, flexible motor control with braking, communication, and protection features suited for a variety of industrial and commercial applications.
