Data Connector (section):
Over 15-pin SUB-D (male) there are the following control options:
- 1x PowerOn control signal
- 2x PWM input channels (e.g. for RC remote control; THR / AUX)
- 2x independent RS232 interfaces for computer remote control and/or interconnection of several turbines
- 1x Analog voltage regulation / sensor input
- 1x JetCat bus interface, e.g., for connection of GSU and/or other JetCat accessories (LCU / flow sensor / BMS system, etc.) CAN bus interface for control and data reporting
Standard Version:
The standard P300-PRO Engines have a "normal" starter motor, without generator (to save costs, e.g., for hobby applications). With the "JetCat-PRO" interface, the engines can easily be used for RC model applications. The PRO interface has integrated the full functionality of the telemetry adapter.
Generator Version PRO-GL:
These versions consist of a brushless and non-contact starter/generator system. The generator is "soft coupled", i.e., it rotates at a lower speed than the turbine shaft itself (patent pending). A built-in and integrated DC / DC converter with additional charge control enables buffering / recharging of the turbine battery. The charging system supplies energy to the engine battery at idling speed. Electrical power of this charging system is approx. 85W. The "soft" coupling of the generator limits the power output.
Generator Version PRO-GH:
This version consists of a brushless and non-contact starter/generator. The generator is "hard" coupled to the turbine shaft (but without mechanical contact), i.e., it rotates at the same speed as the turbine. This configuration allows a much higher power output of the generator (900W!). It is supplied with an unregulated 3-phase alternating current supply. The three-phase voltage varies proportionally with the turbine speed. Typically, the measured no-load DC voltage is approximately 12V / 7.5A (33,000 1/min) and 35V / 22A (100,000 1/min) when charged with a 1.5 Ohm resistor behind a rectifier network (6x High Power Schottky diodes).
