Motor Soft Startup Control Equipment
|
| |
|
 Sphere of application： |
| The product fits for the Soft Startup Control of High/ Middle/ Low Voltage three-phase asynchronous Motors. |
| Main Characteristic: |
◆ The product gets rid of traditional control mode, and reduces the effect to power grid while electromotor starts up.
◆ Adopt advanced singlechip, bring in the newest and mature technology, and realize comprehensive digital intelligent control.
◆ High definition LCD, human-computer interaction interface, easy to operate.
◆ The protection function of soft startup and extension.
◆ Standard communication interface of RS-485 or CAN2.0, completely realize remote control and group control unattended operation, which keeps in step with the international technology field.
