Medium Voltage Soft Starters: HRVS-DN

HRVS-DN

Ratings: 2300-15000V, up to 48MW
The HRVS-DN is a reliable, heavy duty soft starter and the ideal solution for medium voltage motor
applications. Sophisticated, digital motor control ensures smooth acceleration and deceleration
as it minimizes the effect of high in-rush current and mechanical torque shock.

Setting a New Standard

The HRVS-DN is the latest generation, digital Medium Voltage Soft Starter designed for use with standard MV AC induction motors. With advanced features such as enhanced motor protection, starting curves, unique voltage measurement and many years of field-proven reliability, the HRVS-DN is the best choice for starting medium voltage motors in the most demanding applications.

Control Inputs & Outputs

  • Control voltage: 110 - 120VAC, 50/60hz standard, (220-240VAC or 110-220VDC optional)
  • Separate inputs for Start, Stop (Emergency) and Soft Stop
  • Two programmable External fault inputs
  • Aux. contacts - three N/O relays, 8A, 250V, 2000VA:
    • Immediate Relay - changes state upon start signal, adjustable ON & Off delay. Returns to original state upon voltage outage, fault, stop signal and soft stop signal. It can also be configured as a "shear- pin alarm" contact.
    • End of Acceleration Relay - operates upon completion of starting process, adjustable On delay. Returns to original state upon voltage outage, fault, stop and soft stop signals
  • Fault Relay - can be programmed as:
    • Fault - changes state upon Fault, returns to original state upon reset
    • Fault-Fail-Safe - changes state upon control voltage connection, returns upon fault
  • Insulation Alarm relay - changes position upon insulation detection at a pre-programmed level
  • Insulation Alarm - continuosly checks motor insulation for problems. Alarm and Trip levels are programmable
  • Communications: RS 485 with MODBUS, PROFIBUS or MODBUS-TCP
  • Analog Output of motor current (programmable 0 - 10 VDC, 0/4-20mA or inverse)
  • Motor Protection Relay
  • Synchronous motor control (brushtype or brushless)
  • Multi-motor starting
  • Continuous line-ups with horizontal bus bar connections
  • Metal Clad design
  • IP-31 - IP67 (NEMA 1 - 4X) enclosure options
