Mtroniks True Torque DCI250-24 T Instruction Manual

DC MOTOR SPEED CONTROLLER
MODEL: DCI250-24 True Torque
TM
Thank you for choosing Mtroniks to control your model.
Overview
For over 20 years Mtroniks have been at the forefront of electronic speed control design and
manufacture for the hobby industry.
Our products are designed and manufactured entirely in house in the UK. The DCI range of
controllers has been developed over the last 4 years. The extensive research and design program
looked at every aspect of the problems associated with the speed control of large scale models.
We hope you will find the DCI range of controllers is refreshingly different in many ways; it's not
designed down to price. We developed a strong core of electronics which during rigorous testing,
has proven to be 'well on top of the job'
The use of a large and powerful computer core has allowed us to incorporate features and
protection measures not usually found on these types of controllers. These particular controllers are
aimed at large locomotives of 3 ½ " gauge and up. This is where we have tested extensively, actually
in real applications.

Motor torque control system

Accurately measuring the current in the motor can be a difficult problem to solve in a model speed
controller. For this reason, DC motor speed controllers normally control and if necessary limit the
battery current.
However, at low motor speeds and high torque this can lead to severe motor overload because the
current in the motor can be much higher than the average battery current.
Our new control system monitors every motor pulse and if necessary, adjusts the pulse to keep the
motor current (Torque) to the maximum value set on the current control pre-set.
The usual problems of brush burning and motor overheating which occur because of magnetic
saturation in overload are prevented.
