PowerBox P2 Servobridge
Product Details
Description
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.
