This is the Futaba DLPH-3 MAX 60A 10ch Dual RX Link Power Hub

An intelligent safety device that offers twin receiver redundancy, gyro attachment, connection of 10 high performance servos and much more

Futaba’s DLPH‑3 Dual Rx Link Power Hub is a compact, high‑current switching unit designed for large R/C aircraft. It allows pilots to link Futaba S.Bus/S.Bus2 receivers so that if the main receiver loses signal, the back-up receiver will be seamlessly utilised to prevent control system failure. With the ability to PWM connect 10 high voltage, high performance servos and handle an attendant peak instantaneous current draw of up to 60A, the DLPH-3 is an all-in-one solution to managing the distribution of power, telemetry and current whilst supplying a stabilised voltage to the twin receivers, allowing them to do what they do best and maintain Futaba’s rock-solid and dependable transmission link. This latest DLPH Power Hub also includes an option to add Futaba’s powerful GYA573 6-axis gyro using the S.Bus2 system. Compatible battery technologies include a 2s LiFe and 2s or 3s LiPo pack with the system’s telemetry sensor function constantly monitoring and reporting the battery voltage. Meanwhile if the DLPH-3 detects a battery level at start-up of less than 30 or 40% it will not transfer power to the receivers.
