PowerBox Competition SRS
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 required between the receiver and the PowerBox to a single cable. It is also a straightforward matter to connect a second receiver to the system which then assumes complete control of the model without restriction if the first receiver should fail to pick up a signal. In the case of Spektrum and Jeti equipment additional receivers are not required; only the satellite receivers are connected to the Competition SRS.
The Competition SRS can output up to fourteen channels regardless of the radio control system with which it is used. Four of them are equipped with a servo-match function.
The purpose of servo-matching is to adjust the centre point, end-points and direction of rotation very accurately for each servo. This means that multiple servos connected mechanically to a single control surface can be fine-tuned to operate exactly in parallel preventing the servos working against each other. They are able to develop their full power and consume less current. Servo-matching can also extend the effective life of your servos enormously.
However, servo-matching also allows functions to be linked, avoiding the need for two channels at the transmitter. As an example: the left and right landing flaps can be operated using just one transmitter channel as the direction of rotation and the servo end-points are adjusted at the Competition. This saves channels and in many cases makes the transmitter programming procedure much easier.
All the settings are programmed using the SensorSwitch in conjunction with the high-resolution OLED screen. All the menu points are displayed in full text form on the screen - rather than as abbreviations - which makes it much easier to understand the procedure.
The Competition SRS offers the option of a telemetry link with various radio control systems. This facility enables the pilot to view the voltage and residual capacity of both batteries on the transmitter's integral screen. The telemetry interface is simply connected to the receiver using a patch-lead; the TM1000 telemetry module is only required with Spektrum equipment. The receiver then sends the data directly to the transmitter screen. Alarms - such as battery failure - are also generated at the transmitter itself.
The high-resolution OLED screen displays the voltage and residual capacity of both batteries as well as the output voltage actually present.
The Competition SRS delivers a regulated output voltage of 5.9 V or 7.4 V, making it a great choice for standard 6.0 V servos as well as HV systems. In both cases the constant output voltage ensures consistent running and extended effective life for your servos.
The PowerBox Competition SRS can be updated using the USB interface adapter (not included). This means that future expansions - such as additional telemetry systems - can be loaded and used in just a few minutes.
Please note: Futaba S-Bus II receivers not compatible
Note: DO NOT FLY ON FRAME LOSS SCREEN. Always fly on Dash Board Consumption Screen.
Note: The PowerBoxes (with the exception of the BaseLog) will not work with the Spektrum Power Safe receivers. We recommend you use the AR 9000 or the JR 921.
