TVC-B30
30A dual speed controller for 1/10 scale and larger RC tracked
vehicles
The controller contains all components for controlling two DC motors in a
tracked vehicle.
The behavior of the integrated mixer can be set for different vehicle types.
The controller can thus be set for full tracks, half tracks and wheeled ve-
hicles with differential drive. In addition, there are variants for historical
tracked vehicles without tableturn as well as the possibility of inertia simu-
lation.
The controller is equipped with BEC and has an EMK brake, which is released
in the middle position of the throttle and steering stick. The braking effect
can be set either via an RC channel, or fixed.

1 Note
Installation of the module requires intermediate to advanced modeling
skills. Soldering skills are required to connect the wiring. Inexperienced
modelers and persons aged under 16 years old should seek the assistance
of an experienced modeler. Always switch off power when working on
the wiring. Especial take care when connecting more than one receiver
energy source. Prevent the device from getting wet. Check loads before
connecting them to the modul at a current limited, or fuse protected
source.

2 Introduction
The controller is designed for an input voltage range from 6.5V to 24V.
This means that the controller works with the 6 cell NC packs commonly
used in the RC car sector, but also with lead batteries up to 24V. Two stan-
dard automotive fuses protect the model and the battery from excessive
currents.
The controller has a built-in BEC circuit to power the receiver from the drive
battery.
Please note that the removable BEC current decreases as the supply voltage
increases.
To disconnect the internal BEC regulator from the receiver supply, a jumper
must be removed.
As a failsafe function, an extensive plausibility check of the transmitter
signals is integrated in the software.
In addition, the controller has a temperature monitoring of the output
stage.
It switches off at 75°C and can be switched on again at 65°C and above.
To do this, the transmitter sticks must be set to the neutral position to
prevent a sudden start after the controller has cooled down.
2.1 Technology
The controller is microprocessor controlled. The processor operates with
16MHz clock frequency.
The output stage is constructed of N-channel MOSFETs, which have an
inrush resistance of only 0.008 Ohm and a continuous current capability of
60A. Three of these transistors each form a power stage branch, enabling
peak currents of up to 180A. To make effective use of the low internal
resistance, the output stage transistors are driven by sophisticated MOSFET
push-pull output stages with integrated charge pump.
Under normal ambient conditions, a continuous current of 30A is achieved.
The controller operates with a PWM frequency of 16kHz.

3 Functional description
3.1 Manual control
A radio remote control with at least one proportional channel is required
to control the module. To use all functions, four RC channels are required.
3.1.1 Channel 1 - proportional forward/back
Direction of rotation for the motor. From the throttle channel is also derived
reverse light on/off, brake light).
3.1.2 channel 2 - proportional left/right
The control of the turn signals is derived from this channel. It is usually
connected to the steering channel with a V-cable, parallel to the steering
servo. If the channel is not connected, the turn signals only function as
warning turn signals.

4 Installation
Six M3 screws are provided for mounting the controller. The drill holes are
partially located under the plug-in terminals. If necessary, the controller
can also be screwed onto an aluminum surface to increase the cooling
capacity. In this case, the heat shrink tubing in the contact area should be
removed and thermal paste should be used.

5 Connections

Figure 3: Assignment of the connector for power supply
Power is supplied via the green, plug-in screw terminal. Please pay atten-
tion to the correct polarity of the supply voltage! (see figure 3).
It makes sense to include a switch in the positive supply line to the battery
to switch the model on/off. Never switch the minus in RC model building,
because the minus also the reference potential of the servo signals.
There are two automotive fuses for the motor output stages on the circuit
board. They are pluggable and can be easily replaced if necessary.

If one of the power stage fuses has blown, the BEC still works and the LED
indicates the function. However, the corresponding motor output stage
no longer supplies power. In addition, the BEC circuit also has a fuse. This
is soldered onto the circuit board. If this fuse has blown, the BEC no longer
supplies voltage and the controller no longer shows any function.
5.2 Connecting the motors
Black, plug-in screw terminals are provided for the drive motors. One
motor is connected to each screw terminal. The motors must be radio
interference suppressed, as is usual in model building.
5.3 Connecting the servo cables
The controller is equipped with JR servo cables. The pinout is shown in
figure 4.
