The Robbe RO-BEC's are very powerful separate power supplies for RC models of all kinds. To meet today's requirements, the switch mode BEC's have a selectable output voltage of 5, 6 or 7.4V for operation with HV servos. The RO-BEC's have a wide input voltage range of 7-25.5V (2-6S LiPo) and achieve an efficiency of up to 93%. Output voltage 5.6 or 7.4V. The dimensions and weights are kept very small without sacrificing safety functions such as overcurrent or temperature. Four different sizes in 4,6,8 or 12A are available. Output voltage selection: Jumper. Specs: * Ouput Voltage: 5,6 to 7,4V. * BEC Amp. contines: 4 A. * BEC Amp. pics : 6 A. * Input Voltaje: 7-25,5V.
