High voltage Solid soft starter

The motor soft starter is mainly applicable to the control of and protection for the starting and stopping of squirrel-cage type asynchronous and synchronous motors. And the starter is composed of several thyristors in series-parallel,and it can meet different current and voltage requirements.

CMV series high voltage solid soft starter (hereinafter referred to as soft starter) is a high voltage motor softstarter designed with  up-to-date concept, and mainly applicable to the control of and protection for the starting andstopping  of squirre-cage type asynchronous and synchronous motors. The starter is composed of several thyristorsin series-parallel, and it can meet different current and voltage requirements.

Protective functions:

• Open-phase protection?Cut off any phase of primary power supply in the course of starting or operation.
• Over-current protection in operation?Operational Over-current protection setting: 20~500%Ie
• Unbalanced phase current protection?Unbalanced phase current protection: 0?100%
• Overload protection?Overload protection grade: 10A?10?15?20?25?30?OFF
• Underload protection?Underload protection grade: 0~99%; Action time of underload protection: O~250S
• Start timeout?Start time limit: 0?120S
• Over-voltage protection?When voltage of primary power supply is 120% higher than rated value,over-voltage protection is enabled.
• Under-voltage protection?When voltage of primary power supply is 70% lower than rated value,under-voltage protection is enabled.
• Phase protection?Allow to work with any phase sequence (through setting parameter)
• Ground protection?Protection available when grounding current is higher than set value
