DPS-25 Battery Backer 25A with Switches
The DPS-25 is used to safely and wear-free turn on a receiving system, provide it with high current for best servo performance while increasing security by using 2 separate receiver batteries for battery redundancy. Of course, the DPS-25 can also be used with a single battery as a pure receiver switch.
In order to be able to use the optimum performance of powerful and fast servos at all, a power supply is required which leads the necessary, high currents without losses directly to the servo sockets on the receiver.
In addition, the power supply must still work even if one battery fails. These security features are provided by the DPS-25, while minimizing susceptible components. This results in optimum protection against vibration and contact problems. The switching output stages used ensure the highest and lossless current flow, the internal resistance is considerably lower than the contact resistance of mechanical switches.
Due to the high cable cross-sections in the supply lines to the receiver, the maximum current is passed directly to the servo jacks, so the servos can develop their potential power and performance in the first place.
The DPS-25 has the tried and tested T-connector system as battery connection, and 3 original Futaba connector cables (contact socket) are mounted on the receiver side. These special contacts exclusively allow continuous currents of up to 6A, the highest value for this plug-in system at all. The cable cross section is 0.5mm. The negative conductor is made of silver. Thus, the full power of the battery backer or the battery used, can be forwarded directly to the servo cables.
NOTE: Input voltage = output voltage, no voltage reduction, the servos are supplied directly with the battery voltage!
