Description "FUTABA Dual Link Power Hub DLPH-1"
AFETY FIRST! With the Futaba Dual Link Power Hub DLPH-1 you quadruple the safety in your model by operating two S.BUS/S.BUS2 receivers and two batteries in parallel. In the event of a problem with the main receiver or one of the batteries, the DLPH-1 will switch to the second receiver or battery in a flash. But the DLPH-1 can do so much more...

The Futaba Dual Link Power Hub DLPH-1 is designed to provide high current power to Futaba S.BUS receivers and normal servos as well as S.BUS/S.BUS2 servos. The servos are connected to the DLPH-1 at the corresponding servo outputs. These supply the servos with power and with the position and control signal. A single connection cable between the DLPH-1 and the receiver is then required for the power supply of the receiver itself and the signal transmission.

If several servos have to work at the same time with a lot of power and/or high speed, this basically poses a problem for the power supply of the servos, because power and speed always go hand in hand with high current requirements. This current demand cannot be provided sufficiently for the battery via the single plug-in connection directly at the receiver, so a "bottleneck" for the necessary servo current is created. In case of need, the voltage collapses, the servos become less powerful or slower or both. In the worst case, they even stop and the receiver fails. Depending on the current requirement. By using the Futaba Dual Link Power Hub DLPH-1 the current flows directly from the DLPH-1 to the servos.

Principle of battery backer
Battery backers are used to provide redundant power to a system by using a second battery. This results in "battery redundancy". Two accumulators are used, so that in case of failure of one accumulator the other one maintains the power supply of a system. In principle, this would be easy to solve by simply connecting a second battery in parallel to the system. Unfortunately, "Ohm's law" gets in the way: current always flows from a higher voltage to a lower voltage... So from the battery with the higher voltage to the one with the lower voltage - always. Never will two batteries have the same voltage or load capacity. So the current of the better battery does not flow to the system, but to the "worse or empty battery". This usually leads to the complete destruction of both batteries and to a crash of the model.

  • The servos with high current requirements are connected to the DLPH-1, no longer to the receiver.
  • The DLPH-1 has two XT60 high current connections for two receiver batteries due to the built-in battery switch. Their voltage is then fed directly and without loss to the servo sockets on the DLPH-1 (via the built-in battery switch).
  • The position and control signal for the servos is routed separately from the receiver to the individual plug-in connectors. In order for the receiver to work, it receives its voltage from the DLPH-1 via a single patch cable (S.BUS signal, all in parallel).
  • The positioning and position signal is routed via the S.BUS to the plug-in connections of the DLPH-1.

The operating current for servos and receiver is thus "split".
  • Why high current for servos, what happens in case of undersupply? For the large, dynamic, very short fluctuations of the current demand (current peaks) of today's servos, an unhindered current supply to the servos is absolutely necessary. Therefore, not only high-current batteries must be used in the functional chain, but also connectors and cables that can supply the high current to the servo sockets.
  • Classical voltage controls work rather insufficiently, because they are always "slower" than the fast (very dynamic) fluctuating current demand of the servos, and also slower than a high-current battery, which can supply these current peaks by all means.
  • But modern servos need just these current peaks to be able to deliver their actual power. Therefore, there is nothing better for powering such servos than to lead the battery voltage to the servos in the most direct way, without any voltage regulation or other resistances like unsuitable connectors or long or thin cables.
  • The best way to adapt to different servo voltages is to use appropriately matching battery types. LiFe batteries for all servos, or LiPo batteries for LiPo(HV) servos. This eliminates the need for voltage regulation.
