If you’re using a 6V dc motor in your Lima or Hornby ringfield motor conversion, and you’re using DC control or a DCC decoder without CV5/CV6 functionality, you’ll need to consider a diode voltage dropper to protect the motor from over-voltage and current.
This brand new style of voltage dropper will drop around 1.5 volts, and is ideally suited for our LA2, HA2 and HA8 motor upgrade kits.
It features a specially-designed printed circuit board and is pre-assembled, saving you preparation time and hassle. It will reduce the voltage going to the motor by ~1.5v, adding protection to any 6V motor and helping to achieve a far more prototypical speed.
We also stock a a range of self-build voltage dropper kits to fit different installation situations and soldering skill levels (including our low-profile surface mount (SMD) components kit) and our through-hole components kit), and a special -3V pre-made volt dropper that’s a great match for our LA3B, LA5 & HA5 motor kits and it strongly recommended for those installations.
The kit comes with basic wiring instructions. Detailed instructions are available in our ringfield adaptor kit instructions booklet which is available via our website.

Looking for something that’s lower profile?
If you need a slimmer solution to fit in a small corner or fix to the chassis or body, our tiny surface mount diode voltage dropper kit provides an alternative option to this through-hole kit. You can order it here.
