Specifications:

Actronic 120A Electronic Speed Controller for Brushless Motors

Voltage range: 14-52V (60V)
Dimensions: 88x52x24 mm

Modelers are constantly demanding more and more power, and this can be achieved by designing a system with higher current drain and also with a higher cell-count battery.

The new Actronic 120 fulfills both requirements. The Actronic 120 offers the same functions as the Actronic 80-32, but can now cope with up to 12 Lithium cells or 38 NiCd / NiMH cells, with a maximum permissible current of 120 A.

The high maximum current capacity is achieved through the use of MOSFETS of even lower loss design, together with a larger heat-sink. As with all new Actronic controllers, this type also employs ceramic capacitors at the battery input. They are ultra low-loss types and are extremely reliable.

For the first time the use of a large heat-sink and ceramic capacitors enables this unit to operate under arduous conditions (continuous running at part-throttle settings) with high reliability; a typical example would be a high-performance model helicopter.

The Actronic 120 controller features jumpers which are used to set it for forward / reverse operation, and to switch the EMF brake on and off. The commutation is adjustable, so that the units work with maximum efficiency with our Actro 60 range and LRK motors.

Speed regulation (governor) mode is possible with these controllers with or without our Control panel V3, although the governor settings and maximum speed are fixed if the Control panel is not used.

New controller for the sensorless Actro motors, especially designed for long duration use in high performance ranges. The losses remains small by use of efficient power mosfets. A large heat sink allows a reliable cooling to supress heating of the controller-a necessary property for long flights under high power conditions.

Typical applications are large scale models, aero-towing tugs as very high performance helicopters.

Like Actro motors, Actronic controllers are developed for rough, everyday application.
Numerous safety features like:

* Temperature supervision
* Undervoltage supervision
* Current limitation
* Protection for motor start by mistake
* Fail-safe function for PPM receiver
* Opto-coupler for reduction of disturbances
