HRVS-DN Medium Voltage soft starter Advantages at a Glance for the HRVS-DN Medium

WEM medium voltage soft starter is considered as the most reliable soft starter in todays' Industrial and Marine markets ? The HRVS-DN is a third generation, digital, Medium Voltage Soft Starter, designed for use with standard MV asynchronous and synchronous motors. This highly sophisticated soft starter ensures smooth, step-less acceleration and deceleration, eliminating high inrush current and damaging mechanical torque on startup and mechanical wear on stopping. The HRVS-DN is available as a stand-alone product or as part of a complete system including Line and/or Bypass Contactors. Additional options for medium voltage soft starter include Load Break Switch, Motor Protection Relay, Digital Multi-meter, etc.


We can customize our medium voltage soft to provide for every application
