PowerBox-Systems is breaking new ground with the PowerBus !

PowerBus

The PowerBus is the basis of a completely new method of wiring servos. The PowerBus consists of a three-core cable which supplies current and signal to the servos connected to it. At first glance this is nothing unusual, but the big difference lies in the signal wire.

When conventional servo signals are transferred, the signal wire always carries the information for one individual servo only - this is a PWM (Pulse Width Modulated) signal. In a servo bus system the signal wire carries positional information for multiple servos in digital form. The information for individual servos includes address data, and since each servo is assigned its own individual address, it can - provided that it has a decoder - read out “its” information from the data stream and convert it into a movement of the control surface. PowerBus to PWM adapters can also be employed to enable the use of servos without their own decoder; in this case the adapter carries out the decoding.

The advantage of this arrangement is obvious: all you need is one three-core lead in order to supply different information to several servos. The wiring is much simpler, and there is also a significant weight saving.

The servo distributors which we have developed in-house are protected against short-circuits in the power supply lines and the signal line! This means that, if one output is shorted out at a servo distributor, within a few micro-seconds that output is switched off, and the bus lead remains active.

The new Royal SRS and Champion SRS feature two integral high-performance PowerBus outputs. These make it possible to implement two PowerBus branches without further accessories, and this applies to all radio control systems: Spektrum, Futaba, JR, Jeti, M-Link and HoTT.

If additional branches are required, a lead can be duplicated using a PowerBus Splitter.

The two PowerBus to BUS and PowerBus to PWM adapters adapt the servos to the bus, regardless of whether the servos in use are bus-enabled or conventional types.
