The Gemini II is the logical development of the PowerBox Gemini, which has been unchanged since 2005. The revised design incorporates ideas gleaned from customer requests and continued testing. The Gemini II is considerably higher performance than the earlier model, since the case now consists of a high-quality machined aluminium heat-sink. Numerous supplementary features have also been added. For example, the pilot now has two options for activating the system: either by push-button using the SensorSwitch, or using a magnet. This also allows the implementation of a concealed installation. When using the magnet option a integral buzzer indicates the ON and OFF state.
Like all power supply systems from PowerBox Systems, the Gemini II boasts consistent redundant construction: two regulators, two controllers and two integral Hall sensors ensure a totally reliable power supply. The external SensorSwitch activates both electronic switches simultaneously. The tri-colour LEDs in the SensorSwitch indicate the battery status in four stages. The battery inputs take the form of MPX high-current connectors. The output voltage is double-regulated, and can be set either to 5.9 V or 7.4 V.
The Gemini II is a perfect regulator for those seeking the best reliability and redundancy for high performance models like large helis, high power EDF units, or turbine jets. The Gemini II is made in Germany by PowerBox Systems.
