The Digi Hat from DCC Supplies is used to convert Graham-Farish chassis safely to DCC in minutes!

Supplied with Kynar heat shrink tube. Tougher than standard tubing, and half the thickness!

• So, the spring is a fuse?
  The spring is made from 0.32mm (28awg) Beryllium copper wire, which has a capacity of 1.4 amps. Or, put another way, most ‘N’ gauge decoders provide 0.8 -1 amps. The current draw of an average Farish motor is 0.3 – 0.4 Amps.
• OK then, will heat draw the temper of the spring?
  Beryllium copper is tempered at 460° for an hour. With a loading of 1 amp the temperature increase of the spring is negligible.
• Does the spring get hot?
  No. At 1amp heat generation is 0.003 W/second (per 1000m of wire!), heat dissipation is 105 W/m*k, again, well within tolerances!
• Will the DiGi-Hat™ melt?
  No. The material has a melting point of 140°C.
• Is it true the DiGi-Hat™ absorbs water, expands, and splits?
  No! The material used (a copolymer of Polyoxymethylene) is designed for use as a bushing material, and is specified at less than 0.5% absorption at 100% immersion. (measured by ISO 62- Sat/23C- and after all, we’re not discussing submarines here!
• What makes this the best solution?
  DiGi-Hat™ is a designed and engineered solution. It uses high quality materials chosen specifically for the task, and engineered by a specialist company with over 35 years of experience, under compliance with BS EN ISO 9001 : 2000
