As time passes, our collaboration with M/s. Fairford Electronics Ltd., UK has developing more bonds and a successful association with technical support from FEL. We at ‘Jayashree’ are introducing a ‘New Advance Soft Starter’ i.e. DFE Series which Ranges from DFE 2 to DFE 38.

The products specs at a glance..

Low Cost, Internally Bypassed Soft Starter

Main Features

• Internally Bypassed: Reduces cost because when the Soft Starter has reached top of ramp the Thyristors are bypassed, this reduces heat and the size of the cabinet required.


• Substitution of Star/Delta Starters.
• Lower maintenance costs
• Less stress on auxiliary equipment when starting
• Reduced down time
• Low cost of ownership


• Simplified Installation.
  Rapid build and install time.


• No need to change wiring configurations: All six wires of the start delta configuration can be used to minimise installation and design costs.


• Competitive with Star/Delta Starters.
• Longer life
• Less maintenance
• Lower cost of ownership
