Description
Variable Frequency Drive – 380V in / 380V out
3 Phase
A VFD slowly begins from zero speed and gradually work up to higher speeds. It offers precise, energy-efficient control of force and torque.
When using a VFD, less current and power are required to start an AC motor. Thus, the problem of voltage sag and the damage it can inflict on expensive machinery and electronics is eliminated. |
This gives the AC motor longer service life through smoother startup process hence more savings on maintenance costs.
Capabilities:
Precise electrical control:
- Speed levels are delivered as-needed avoiding slow operations that would otherwise use too much energy with fixed speed drives.
- The VFD can be programmed to restrict torque, keep the motor from surpassing a set torque threshold thereby holding back excess power that a fixed-speed controller would end up using wastefully.
Protection functions
It can implement power-on motor short-circuit detection
Input/output phase loss protection
Over current protection
Over voltage protection
Under voltage protection
Overheating protection
Overload protection.
Our VFDs also support Modbus Communication Protocol with local or remote parameter control
Why use a VFD?
Energy savings
Intelligent motor control
Reduction of peak current
Match the speed of the drive to exactly what your process requires
Lower noise levels from equipment
Reduce mechanical stresses on equipment to extend their lifetime, especially on startup with ramp up starts, instead of slam in starts
For the vector control of three-phase AC asynchronous motors and three-phase AC permanent magnet synchronous motors, as well as separation control.
SVC torque control is also supported – and better low speed stability and better low frequency load capacity
Up to four motor parameters can be set, and four motor switchings can be controlled
AIAO accuracy range is within 20mv
