Medium Voltage - Soft Starter


Heavy-duty Medium Voltage Soft Starter

Medium Voltage

Heavy-Duty Soft Starter

2.3 - 13.8kV, up to 48MW


The HRVS-DN is a heavy-duty Medium Voltage Soft Start, designed for all Medium Voltage AC induction motors. The HRVS-DN’s sophisticated motor control technology ensures smooth acceleration and deceleration as it minimizes the effect of high in-rush current and mechanical torque shock. 

Advanced features include customizable starting curves, unique voltage and current measurements, as well as monitoring capabilities. The flexible design, enhanced motor protection and a superior global reputation make the HRVS-DN the starting solution of choice for Medium Voltage applications - even under the most demanding conditions.

The HRVS-DN’s flexible configuration is designed to meet the requirements of new applications, retrofits in addition to OEM customization. 

It is available with Marine approvals and with the ProGear cabinet- Solcons’ fully Type Tested Arc Resistant switchgear

The advanced medium voltage control panel features an innovative design with new communication and control capabilities, with power and expansion capabilities that deliver a modular concept to enhance the end-user experience.
