HRVS-DN Application Specific Software and Applications

Joliet Technologies is now offering the Magnetek Line of Soft Starters.

Magnetek HRVS-DN Medium Voltage Soft Starters 

Application Specific Software

Starting from Diesel Generator
Wide 45-65 Hz auto-tracking frequency to overcome voltage and frequency instability. Designed especially for marine and off-shore industries, or any system operating from a generator.

Synchronous Motor Starting
Optional module allows you to utilize your existing synchronous motor.

Application Specific Software - Starting from Diesel Generator�- Synchronous Motor Starting�

Pump and Special Load Control
Magnetek Soft Starters eliminate two major problems:

  1. Water Hammer During Stopping
    The Pump Control feature enables selection between three voltage ramp-down curves or a torque curve, preventing a stall condition which eliminates Water Hammer.
  2. Over-Pressure During Starting
    The Pump Control also enables selection between three voltage ramp-up curves, as well as a torque curve, to reduce peak torque.Current ramp is available for special loads.
