TruSpeed MT I Analogue Mosfet/Transistor PWM Controller NO LAUNCH

TruSpeed MT I Analogue Mosfet/Transistor PWM Controller.

Two simple adjustable controls for Sensitivity and Brakes on the MT I make it easy to use and quick to adapt to your racing style, car, and track conditions.

Pulse Width Modulation (PWM) drive controller with unique Transistor braking.

• Brake adjustment (with automatic HOLD)
• Trigger return spring tension adjustment
• Current rating of 12A peak and handling 5A constant
• User-Changeable Single and Double Finger Trigger
• Now with 36 step wiper element and 9 point contact
• Auto reset PTC fuse for over-current protection
• LED with triple function
• Comes with 1m of cable fitted

Speed Control:

This is an FET PWM system. As the trigger is pulled, the PWM pulses to the car progressively widen to increase the speed of the motor.

Brake Control:

Turn Clockwise to increase Braking.

This is a Transistorised DC brake system. A single rotary control sets the braking strength and has a built-in hold circuit to release the brakes once the car has slowed to a speed relative to the amount of brake you have selected. The useful feature of this unique design is that the motor drives the brake circuit in such a way that the faster the car is going, the harder the brakes are applied. As the car slows, the brakes are proportionally released to give very balanced and predictable control. The brake and hold remain balanced to leave you free to race confidently. The braking action is strong at the maximum setting, but short circuit brakes are not available on this model.

Sensitivity Control:

Turn Clockwise to increase Sensitivity.

This adjusts the trigger wiper sensitivity to enable you to set the controller feel for any car or track condition. There is a built-in CURVE control circuit (similar to the PWM controller) which works automatically together with the sensitivity adjustment to give quick and easy settings. As the Sensitivity is turned up, so the initial start speed also rises slightly to match.

The little blue pre-set adjustment on the right hand side of the wiper element provides an adjustment for the range of the MODE function set on the contact board via the solder bridges.

Power LED:

Illuminates to show that power is fed to the controller.

Extinguishes when full power is delivered to the car.

Goes very dim if the trigger is pressed while no car is on the track, or if the car is on the track but the braids etc. have a problem.

TruSpeed Slot Car Controllers - for serious racers

Designed and built in the UK by Steve Hills.

TruSpeed was established by Steve Hills because he could not find a slot car controller with settings that could be customised to suit his driving style. Steve is a very keen slot car racer, and as he raced different slot cars, on different tracks, he realised that a one-size-fits-all slot car controller was not good enough.

Steve worked for many years in the audio industry and is the designer of the modern Bozak range of products.
He applied this design skill to his passion for slot car racing and TruSpeed was born.

Maintenance Tips:

Once you feel a scratchy movement of the wiper fingers over the contacts, or can hear squeaking then it is advisable to clean them. Apply a small amount of switch cleaner/lubricant, lighter fluid, or something similar, onto a cotton bud and, through the air flow slots in the casing, gently wipe over the contacts on the board.

Be sure not to bend the cable at the exit of the handle. The wiring will break from metal fatigue after a while and cause intermittent operation. Wind the cable into a gentle coil as shown in the images and it will last.
