Features

The P²-JR Header is an adapter from a P²-BUS cable terminating in a MPX plug to four UNI

servo leads. A typical use for the adapter is in a wing, where up to four Servos or the P²-Bridge can be connected.

The PBR-26XS serves as a small receiving unit for any PowerBox system, or as an external expansion receiver for PBR receivers. For optimum reception the PBR-26XS can even be installed in a slim fin, since it is only 4mm thick.

The PBR-26XS connection communicates PPM12 and S.BUS as well as PowerBox protocols, such as P²-BUS and FastTrack Out, which means that the receive unit can also be used with third-party flight simulators or helicopter gyro systems.

The receiver units:

Five different receivers are available to match the CORE:

PBR-9D
This is a nine-channel receiver with two redundant receiver circuits. The unit features a P²BUS interface for servo and telemetry data, and an auxiliary output which can be configured either as SRXL bus or as channel 10.

PBR-7S
This is a seven-channel receiver with a single receiver circuit. The unit features a P²BUS interface for servo and telemetry data, and an auxiliary output which can be configured either as SRXL bus or as channel 8.

PBR-5S
This is a five-channel receiver with a single receiver circuit. The unit features a P²BUS interface for servo and telemetry data, while its minuscule size makes it the natural choice for small models.

PBR-26D
This is a satellite receiver featuring two redundant receiver circuits. The unit features a P²BUS interface for servo and telemetry data, and an auxiliary output which can be configured either as SRXL bus or S-BUS. This unit is designed to be connected to our PowerBox power supply systems or a flybarless system.

PBR-8E
This is a eight-channel receiver with two redundant receiver circuits. The unit features 8 PWM servo outputs and telemetry data for battery voltage and RF-data.

With the exception of the PBR-5S and the PBR-8E all receivers have a FastTrack interface with which the iGyro SAT can be easily connected!

Universal servo bus adapter with electronic fuse

The P²-ServoBridge is the key component in an entirely new servo bus technology which presents unprecedented possibilities. If a servo bus is employed, only one cable is required for several servos. The servos are individually addressed, and therefore each servo knows which signal is intended for it. Earlier servo bus systems simplified the wiring in the model; for example, saving multiple plug / socket connections in the wings. The new feature of the PowerBox P²-Bus is that it works bi-directionally! This means: not only can accurate digital signals be fed to the servos, but important telemetry data - such as current, voltage, temperature and other information - can also be fed back to the Core or Atom transmitter. Targeted alarm settings at the transmitter alert the user to defects in good time, so they can be corrected without the need to analyse reams of data. But even that's not all: the parameters of the P²-ServoBridge can be altered directly from the transmitter. The integral electronic fuse can be adjusted to suit the particular servo, precisely to the milli-second and milli-amp. A micro-controller decodes the bus signal, monitors the current accurately and at high speed at the servo itself, and switches the servo off reliably if the set thresholds are exceeded.

This technology eliminates all the disadvantages inherent in simple resettable fuses (polyfuses) - such as temperature dependence or ageing effects. A range of pre-set profiles enables any modeller to find the correct setting for a particular servo even without a knowledge of electronics.

The adhesive pad supplied is used to attach the P²-Servobridge to the bottom or side of the servo case, where it also monitors the servo temperature. In addition to the P²-BUS, the P²-Servobridge works with other bus systems such as S.BUS or SRXL, and even with conventional PWM servo signals. This means that the device can also be used for accurate over-voltage power-off - for example, with retract servos - even when bus wiring is not used. The input signal is detected automatically, and the fuse is pre-set to suit standard servos with an output torque of up to 30kg/cm, so in most applications the P²-Servobridge can be used as a Plug ´n Play device.
