DogZ BolloX - SPEED CONTROLLERS from RobotsRus . . . CyberRaptor Custom speed controllers
160Amp Continuous (Approx 400 Amp Surge) with integral variable current limit and heat sink
These boards are now available . . . . .
The RobotsRus speed controller has been specifically engineered for use in robotic applications. The speed controller performs speed, steering and weapon functions for robots powered by DC motors. The speed controller consists of one Control board and up to four high-power H-Bridge FET boards. The control board utilizes two high performance low power RISC microcontrollers running at 12MHz that gives a throughput of up to 24 MIPS (12MIPS per controller). The H-Bridge FET boards use the latest Automotive power MOSFETs that have ultra low on-resistance and fast switching times. The FET board also incorporates a variable current limit circuit to protect the MOSFETs in a fault or stalled motor condition. Each H-bridge FET board consists of 16 automotive power MOSFETS (8 for forward operation and 8 for reverse operation). The combinations of these two boards provide a system that delivers reliable high switching speeds that ensure ultra smooth speed control.
The control board has up to five standard R/C input channels; four are converted into PWM outputs to interface to the H-bridge FET boards with the remaining one used as an auxiliary output. For the PWM channels each pair of R/C inputs may be individually selected for mixed (single stick) or normal (tank driving) operation. The dead band and brake mode may also be individually selected for each pair.

H-Bridge FET Board:
Note: The FET's are cooled by the aluminium panel that attaches them to your robot - they need NO OTHER cooling.
Surge Current >400A
8 for forward operation and 8 for reverse operation
The H-Bridge FET boards use the latest Automotive power MOSFETs. The MOSFETs have been specifically developed for the demanding automotive industry. The MOSFETs have a junction operating temperature of 175deg.C, ultra low on-resistance and fast switching times. These features ensure extremely efficient and reliable operation. Each H-bridge FET board consists of 16 automotive power MOSFETS (8 for forward operation and 8 for reverse operation). The current limiter monitors the current input from the battery and disables the power MOSFETs in the event of an over current condition. The current limit is variable and may to set by the user to limit the current for particular motors / applications. Limiting the current, for example in a stalled motor, significantly extends the battery life and prevents over heating of the motor.
Pricing: See on line shop for detail
Controller card is now £95.00
FET Board is £120.00 and each board now includes current limiting (which you can adjust by means of a pot on board).
Please note: You need a FET board for every motor you wish to control. Each controller card is capable of controlling four FET boards.
Anderson Power connectors (required for all power connections to boards) - are included in the price of the boards - all you need to do is solder the cables onto the connectors then fit the plug.
