Probably the most user-friendly programmable controller available. Programming is easy, using the display. In use, the display shows the system state and an on-board sounder also indicates any problems.

On-board micro computer uses a RISC AVR microcontroller for repeatable performance, versatility, system fault detection and display, battery monitoring, user programmability, and thermal management.

The programmer and the display are the same unit - in two halves so they can be separated once initial programming is done! The display, once the controller has been installed, is used to show battery state and to give a visible indication of any fault detected. User programming is comprehensive, yet very simple. Of prime importance is the Personality feature - this is the only thing the average user will ever need to change as the controller has build in several different sets of performances, or Personalities, to suit for instance, a ride-on golf buggy, a miniature locomotive, a boat etc. Each personality is separately programmable without affecting the other personalities.

There is no separate, expensive programmer, so user programming becomes economical and sensible even for the low volume user. Contrast this with 'industry standard' controllers, designed for high volume users, where the programmer costs far more than the controller!

All essential inputs are on one 6-way connector. Should the more advanced features be required, these are on a separate connector.

The on-board computer monitors the controller and much of the external system. Should a fault be detected, the computer will not only shut down the controller but will give and indication of the fault on the external display.

An on board sounder gives audible indication of any fault detected. Or it can be configured as a reversing sounder. This feature brings the controller to life during setting up - and makes diagnosis of system faults via telephone easy!

Standard controller comes with base/heatsink plus cover, display/programmer, interconnecting cables from controller to display.

The DMR-203 can be used with one or two Pro-150 controllers. Instructions on how to use them together can be found here.
