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.
Features SRS: Serial Receiver System provides the facility to use receivers with serial interface: Spektrum DSM2 and DSMX (incl. X-Plus channels), Multiplex M-Link, Futaba S-Bus, HoTT, JR X-BUS and Jeti R-SAT2 (PPM, EX and UDI) Servo-Match function: servo centre, end-points and reverse for 4 channels and 8 servos Unrestricted channel assignment for all PowerBox outputs Graphic OLED screen with 128 x 64 pixels Extremely user-friendly menu-based programming using the SensorSwitch 14 channels Signal amplification and interference suppression for all 21 outputs Flight recorder, recording of lost frames, fail-safe events and all battery data Variable frame rate, range 9ms – 21ms 16-bit processor for fast, high-resolution signal processing double-regulated output voltages for receivers and servos regulated voltage with selection facility, 5.9V or 7.4V Connection facilities for Futaba*, Jeti, Spektrum, HoTT and Multiplex MSB downlink bus systems Direct transmission of battery voltage and capacity to the transmitter Separate voltage and capacity display for each battery Minimum value memory alerts the user to voltage collapses Large-area heat-sinks for high regulator performance Regulator monitoring, regulator error indicator Support for three battery types: LiPo, NiMH / NiCd, LiFePo Suppression of any servo feedback currents which may occur Updateable with PowerBox Systems USB Interface connectors
