POWERBOX COMPETITION SRS SENSORSWITCH & PATCHLEADS PBS4420

The PowerBox Competition SRS is the first device in an entirely new generation of power supply systems, and since its introduction it has grown to be the most popular product in our range.

SRS stands for Serial Receiver System: in contrast to conventional battery Backer systems, servo information is transferred using a digital serial signal generated by the receiver. This reduces the number of connections needed between the receiver and PowerBox to a single cable. It is also easy to connect a second receiver to the system, which then takes over control of the model if the first receiver should fail to pick up a signal. In the case of Spektrum and Jeti, only the satellite receivers are connected to the competition SRS.

The Competition SRS can output up to fourteen channels, with four of them being equipped with a servo-play function. The objective of servo matching is to adjust the center point, end points and direction of rotation very precisely for each servo. Multiple servos mechanically linked to a single control surface can be tuned to operate exactly in parallel, preventing the servos from working against each other.

However, matching also allows servo functions to be linked, avoiding the need for two channels in the transmitter. As an example: the left and right landing flaps can be operated using only one transmitter channel, as the direction of rotation and the servo end points are adjusted in the Tender.

The Competition SRS offers the option of a telemetry link with multiple radio control systems. This facility allows the pilot to see the voltage and residual capacity of the two batteries on the transmitter's integral screen. Alarms - such as battery failure - are also generated at the transmitter itself.

The high-resolution OLED screen shows the voltage and residual capacity of both batteries, as well as the output voltage actually present.

The Competition SRS provides a regulated output voltage of 5.9V or 7.4V, making it a great option for standard 6.0V servos as well as high voltage systems. In both cases, the constant output voltage ensures consistent operation and extended effective life for your servos.

The PowerBox Competition SRS can be upgraded using the USB interface adapter. This means that future expansions - such as additional telemetry systems - can be loaded and used in just a few minutes.
