HRVS-DN Medium Voltage, Digital Soft Starter

1500-13,800V, 60-1000A

The HRVS-DN is a third generation, Medium Voltage, digital soft starter, designed for use with standard asynchronous and synchronous motors. This highly sophisticated soft starter ensures smooth, step-less acceleration and deceleration, eliminating current and mechanical shocks on motor and load.

The HRVS-DN may be supplied as chassis type or a complete system including Line and/or Bypass Contactors. Addible options are Load Break Switch, Fuses, Motor Protection Relay, etc

Control Inputs & Outputs

• Control voltage: 110-120, 220-240VAC / 50-60Hz or 110 - 220VDC to be specified
• 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:
• 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.
• 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.
• 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.

Typical Applications

• Fans and centrifuges
• Conveyors and monorail systems
• Pumps, Compressors and Chillers
