7.5kw AC Drive Frequency Converter for Motor Variable Speed Drive

Characteristics:
High start torque, available to achieve 150% of torque output on low speed 0.5Hz.Control method: V/F control, Dynamic torque vector control.
Support many frequency setting methods: digital setting, analog quantity setting, pulse setting, PID setting, communication setting etc.
16 sections, multi-velocity control and PID control.
Support DC braking of stop and external terminal control DC braking.
With overtorque detection.
With auto voltage adjustment. The output voltage would be stabilized automatically when the grid voltage varies.
With jump frequency control, make the system stabler and more reliable on mechanic resonance.
The input and output terminal are auto-program, user could make many working modes according to the needs.
Attached with many fault protection functions: converter unit protection, overvoltage protection, overcurrent protection, overload protection, overheat pretection etc.
 
Various Application
S3100 series is new generation, Multi-function, Vector control inverters. It could widely applied on the fields that have high requirements on the speed control accuracy, torque response speed, low frequency output performance.
