Product Description

The Sabertooth 2x50HV is currently being redesigned. The APPROXIMATE release date is late Q1 (March-ish) 2012. Our small stock of original 2x50HVs is depleted, and we will only be shipping made-to-order units for Warranty claims and not retail or dealer orders. Again, if you have a 2x50HV under warranty, we can still get you a new unit if required! Contact us for more information.

The Sabertooth 2X50HV is one of the most versatile, efficient and easy to use dual motor drivers on the market. It is suitable for high powered robots - up to 120lbs in combat or 500lbs for general purpose robotics.

Out of the box, the Sabertooth can supply two DC brushed motors with up to 50A each. Peak currents of 100A per channel are achievable for a few seconds.

Overcurrent and thermal protection means you'll never have to worry about killing the driver with accidental stalls or by hooking up too big a motor.

Sabertooth allows you to control two motors with: analog voltage, radio control, serial and packetized serial. You can build many different robots of increasing complexity for years to come with a Sabertooth. Sabertooth has independent and speed+direction operating modes, making it the ideal driver for differential drive (tank style) robots and more.

The operating mode is set with the onboard DIP switches so there are no jumpers to lose. Sabertooth features screw terminal connectors - making it possible for you to build a robot without even soldering.

The regenerative topology means that your batteries get recharged whenever you command your robot to slow down or reverse.

Sabertooth has a built in Switching BEC that can provide up to 500mA of power to a microcontroller or R/C receiver. The lithium cutoff mode allows Sabertooth to operate safely with lithium ion and lithium polymer battery packs - the highest energy density batteries available.

Sabertooth's transistors are switched at ultrasonic speeds (32kHz) for silent operation.

Use of our motor drivers with cheap AC adapters is not recommended. Use a battery or at least put a battery in parallel with a DC supply.
