MC-HYDRO 55 REVERSE Graupner 2871 An extremely high-power, high-performance speed controller for demanding applications, with polarity reverse for model boats and ground-based vehicles. Completely encapsulated and watertight. Integral water cooling. Suitable for models such as the PEGASUS, SEA COMMANDER, PORTOFINO and BREMEN 9.
- Maximum load 55 A forward speed.
- Controlled by the latest 8-bit RISC micro-processor.
- Switch rise characteristics optimised for interference suppression and continuous part-throttle operation.
- Latest SMT (surface mount technology) construction.
- Watchdog Control System.
- Variable pulse frequency up to 2,6 kHz, optimised for efficiency.
- The motor output stage is protected by an electronic cycle-by-cycle current limiting monitor circuit to guard against excessive current and
short circuit.
- If the controller overheats it switches itself off automatically for a brief period until an acceptable temperature is reached.
- LED Control Monitor for excess temperature, reverse running, stored excess current indicator and for programming functions.
- Self-Learning System: automatic detection of stick neutral point, stick direction and stick travel.
- The controller is programmed simply by moving the throttle stick; the motor is not needed at all.
- The programmed parameters can be stored.
- Soft start: provides gentle, scale-like acceleration. Especially effective in conjunction with a diesel sound module.
- For perfect heat rejection an, optional cooling system via a brass tubing can be fitted. Operating voltage 8,4 ... 36 V
