Medium Voltage Soft Starter Integrated Motor Insulation Protection

Introduction

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 Multimeter, etc.

We can customise our medium voltage soft starters to solve all of your inrush and starup problems. To see what we can do for you sign up now to become a distributor.

Control Inputs & Outputs for a Medium Voltage Soft Starter

• Control voltage: 110-120, 220-240VAC / 50-60Hz or 110 – 220VDC to be specified at time of order.
• Separate inputs for Start, Stop (Emergency) and Soft Stop.
• Two programmable External fault inputs – will stop the motor 2 sec. after the contact closes
• Aux. Contacts – three C/O relays, 8A, 250V, 2000VA (four C/O relays when Insulation option is used) :
  1. Immediate Relay – changes position upon start signal, with adjustable On & Off delays.
     Returns to original position upon Voltage Outage, Fault, Stop signal and Soft stop signal.
     at the end of soft stopping process. It can also be configured as a “Shear-pin Alarm” contact.
  2. End of Acceleration Relay – operates upon completion of starting process, with adjustable
     On delay. Returns to original position upon Voltage outage, Fault, Stop and Soft Stop signals.
  3. Fault Relay – can be programmed as:
     Fault – changes position upon Fault, returns to original position upon Reset.
     Fault-Fail-Safe – changes position upon control voltage connection, returns upon fault.
  4. Insulation Alarm relay – changes position upon insulation detection at a pre-programmed level.
