The
Slow Speed Charger is designed as an add-on for coaches fitted with W or WA type dynamos and "fools"
the dynamo into thinking it is rotating twice as fast as it actually is. This allows the coach batteries to
charge at preserved line running speed (less than 25mph). The unit (illustrated) is mounted inside the MD
regulator housing and all the necessary wiring is contained inside the housing.

The only external change required is to uprate the dynamo field fuse to No 3 instead of No 2, that is 6A to
10A. This is a precaution only - in theory, the field current is very unlikely to exceed 6A.
The chargers
come with full fitting instructions and operational description leaflet. Unfortunately due to component changes
necessitated by the RoHS directive, the price of these units has been changed to £50 each
(UK only) excluding delivery and fitting (if required). Note that these units are quite heavy (circa 3kg), so
postal delivery is an expensive option. You can order the charger via email on
don(at)gotopcs(dot)net [spam suppressor]. Component procurement for these devices has become very
difficult - "is it worth the trouble?" stage has been reached. Consequently these devices
will only be supplied until current component stocks are exhausted (Dec 2007 - parts for 5 more).
