The 900 series of ROXXY® Brushless Controllers impresses with the new Cool Power FET Technology (not on 908 and 918) and is therefore particularly powerful for a wide range of applications, whether for electric model aircraft, electric gliders or electric helicopters. These controllers are particularly suitable for the ROXXY BL motor series, but can of course also be operated with all other brushless motors. The clock frequency of 32,000Hz provides a very sensitive response, which offers great advantages especially when torquing and when used in E-Helicopters.
The 9100-12 Opto and 9120-12 Opto controllers are universal speed controllers for brushless motors and can be used in aircraft, helicopter, boat and car models: One for all! Selectable forward/reverse operation, with or without brake. In heli mode, speed control function (Governor Mode).
Programming options:
- Model type: Air/Heli, Boat/Car
- Battery type: Lipo, NiCd/NiMh
- Rotation direction normal/reverse
- Brake on/off
- Governor Mode (Heli)
with the separately available Programmer V2 (# M318642) further settings can be made:
- Cut-off voltage
- Behavior at undervoltage (Cut Off Type)
- Motor timing
- Startup behavior
- Control behavior (Governor Mode only)
- Braking behavior (Air Mode only)
- Motor pole count
- Gear reduction ratio
- Display RPM max.
- Display RPM average
- Write data
- Read data
- Save data
These controllers are equipped with the following protection functions:
- POR: Startup protection, prevents unintentional motor startup
- PCO: Undervoltage cut-off. The motor is switched off in time when the battery is empty,
- to reserve enough capacity for the control system.
- hec: High clock frequency (32kHz) for sensitive, magnet-friendly motor control.
- SPS: Super Programming System
- Cool Power FET: New generation of transistors
- RX-Filter: Switches off the controller if the transmitter signal is missing or invalid.
- TP: Thermal overload protection (Thermal Protection) with subsequent power reduction to 70%
