Futaba / ACT PS-25 V2 Electronic Switch
The Power Switch 25 is used to switch on a receiver system safely and without wear, and to supply it with high current for best servo performance. 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 any losses. The PS-25 provides these safety functions while minimizing components that are susceptible to interference. This results in 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 high cable cross-sections in the supply lines to the receiver, the maximum current is conducted directly to the servo sockets, allowing the servos to develop their potential power and performance in the first place.
The PS-25 has as battery connection the proven XT60 connector system, on the receiver side are 2 original Futaba connector cables (contact socket). These special contacts allow exclusively continuous currents of up to 6A, the highest value for this connector system at all. 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.
The electronic high current switch eliminates all wear or vibration problems of mechanical switches. To switch on, simply press the ON button, which then only switches ON the switching electronics (and thus the receiver and servos ), after which the button is no longer effective. The operating current always flows through the power electronics, not through the actuation buttons or switches.
NOTE: Input voltage = output voltage, no voltage reduction, the servos are supplied directly with the battery voltage!
