STEP AS320 Elevator frequency inverter, elevator, inverter

Product detail

Model NO.

AS320

Main Features

Use 32-bit MCU, faster running speed leads to more accurate speed control
Use PIM module, lower loss in switch on and off and longer lifetime
Support one main contactor solution
Support gear and gearless motor
Creative Zero-speed torque compensation technology provides the elevators with good starting ride quality without installing weighing devices
Close-loop vector brings higher performance in control
New PWM dead-zone compensation technology brings less energy loss
Dynamic PWM carrier modulation technology brings less motor noise
Passed the CE and UL certifications
