DESCRIPTION
The DPS-25 is used to switch on a receiver system safely and wear-free, to supply it with high current for best servo performance and at the same time to increase safety by using 2 separate receiver batteries for battery redundancy. Of course, the DPS-25 can also be used with only one battery as a pure receiver switch.

In order to be able to use the optimum performance of strong and fast servos at all, a power supply is required which leads the necessary high currents directly to the servo sockets on the receiver without loss.

In addition, the power supply must still function even in the event of a battery failure. These safety functions are provided by the DPS-25, while at the same time minimizing components susceptible to faults. This provides optimum protection against vibration and contact problems. The switching output stages used ensure the highest and loss-free current flow, the internal resistance is considerably lower than the contact resistance of mechanical switches.

Due to the high cable cross-sections in the feed lines to the receiver, the maximum current is transmitted directly to the servo sockets, allowing the servos to develop their potential power and performance in the first place.

The DPS-25 has the proven T-connector system as battery connection, 3 original Futaba plug cables (contact socket) are attached on the receiver side. These special contacts exclusively allow continuous currents of up to 6A, the highest value for this connector system ever. The cable cross section is 0.5mm. The negative conductor is made of silver. This allows the full power of the battery backer or the battery used to be passed directly to the servo cables.

NOTE: Input voltage = output voltage, no voltage reduction, the servos are supplied directly with the battery voltage!
