1 Robust General Purpose Low Voltage Soft Starters Low cost, internally bypassed non optimizing soft starter A

Robust General Purpose Simplified Installation Internally Bypassed Competitive with Star/ Delta Starters The DFE is Fairford s internally bypassed, non optimizing

production. The DFE is cost effective, low maintenance and has an excellent service lifetime.

To panel builders it is an ideal substitute for a Star/ Delta starter because it fits into a similar footprint, thus simplifying installation.

Internally Bypassed Internal bypassing of the Thyristors at the top of ramp allows for reduction in heat and cabinet size.

2 Robust General Purpose Simplified Installation Internally Bypassed Competitive with Star/ Delta Starters The DFE is Fairford s internally bypassed, non optimizing soft starter which is perfect for panel builders and end users alike The DFE offers easy installation and is designed to be fitted with minimal disruption to production. The DFE is cost effective, low maintenance and has an excellent service lifetime. To the user it offers competitive pricing, soft stopping and the removal of high transient currents. To panel builders it is an ideal substitute for a Star/ Delta starter because it fits into a similar footprint, thus simplifying installation. It is now available from 22 Amps to 500 Amps. Internally Bypassed Internal bypassing of the Thyristors at the top of ramp allows for reduction in heat and cabinet size. Costs are reduced in ancillary equipment and these savings are passed on to the end user. Simplified Installation Rapid build and install time. No need to change wiring configurations All six wires of the Star/Delta configuration can be used to minimise installation and design costs. DFE vs. Star/Delta Starters A competitive subsititution Lower maintenance costs Less stress on auxiliary equipment when starting Reduced down time Low cost of ownership

3 3S Technology Automatic ramp control profiles ensure smooth start and stop performance, delivering stable acceleration and deceleration in all operating conditions. Case Study 3S Technology allows a 30 second soft start and a 30 second soft stop time, which other systems which cannot achieve. Thus being able to attain a Trip Class 30 start duty rating for the heavier duty starting applications. 3S Technology H3 Pump Controls, a division of Triple H Specialty Co. Inc, was challenged to provide a small rural municipal in Alston, Georgia, USA with a high quality, economical, and reliable soft starter solution for the town s new water well project. H3 Pump Controls quickly decided that the Fairford DFE soft starter product had exactly what we needed. The key decision factors in choosing the DFE were, a basic setup soft starter was needed to enable the municipality to maintain the operation of the product after the purchase, with little or no maintenance. An economical approach was needed for the soft starter to help meet the local government s budget demands. A rugged soft start with great reliability was required to keep the confidence of the municipality.
