Features
Synchronous regenerative drive:
Going one step farther than just regenerative braking, a SyRen motor driver will return power to
the battery any time a deceleration or motor reversal is commanded. This can lead to dramatic
improvements in run time for systems that stop or reverse often, like a placement robot or a
vehicle driving on hilly terrain. This drive scheme also saves power by returning the inductive
energy stored in the motor windings to the battery each switching cycle, instead of burning it as
heat in the motor windings. This makes part-throttle operation very efficient.
Ultra-sonic switching frequency:
SyRen 50 features a PWM frequency of 32kHz, which is well above the maximum frequency of
human hearing. Unlike some other motor drivers, there is no annoying whine when the motor is
on, even at low power levels.
Thermal and overcurrent protection:
SyRen 50 features dual temperature sensors and overcurrent sensing. It will protect itself from
failure due to overheating, overloading and short circuits.
Easy mounting and setup:
SyRen has screw terminals for all inputs and outputs. There are four mounting holes, which
accept 4-40 screws. Mounting hardware is included. All operating modes and options are set
with DIP switches – there are no jumpers to struggle with or lose. No soldering is required.
Compact Size:
SyRen utilizes surface mount construction to provide the most power from a compact package.
Its small size and light weight mean you have more space for cargo, batteries, or can make your
robot smaller and more nimble than the competition.
Carefree reversing:
Unlike some other motor drivers, there is no need for the SyRen to stop before being
commanded to reverse. You can go from full forward immediately to full reverse or vice versa.
Braking and acceleration are proportional to the amount of reversal commanded, so gentle or
rapid reversing is possible.
Many operating modes:
With analog, R/C and serial input modes, as well as dozens of operating options, the SyRen has
the flexibility to be used over and over, even as your projects grow more sophisticated. Yet it is
simple enough to use for your first project.
Sabertooth software compatibility: The SyRen 50 is compatible with the Sabertooth
software available for Windows. This software suite can be used to control the SyRen50 from a
PC using a packet serial interface.
