Futaba FURPS10 PS-10 5.2V 7A Voltage Regulator for Servo and RX  [FURPS10]

Voltage regulator for servo and RX

The Futaba FURPS10 PS-10 is an RC-scale voltage regulator designed to provide a steady 5.2V supply for servos and receivers when source battery voltage ranges from 6V to 12.6V. Intended for model use only, it helps stabilise servo and receiver power on electric radio-controlled models where battery voltage can vary under load.

In practice the regulator sits inline with the model's power feed to the receiver and servo rail, supplying a regulated 5.2V rail and supporting peak loads up to 7A. Its role during setup and tuning is to reduce voltage sag that can affect servo torque and receiver stability, making it useful when running multiple high-draw servos or when using battery packs with higher nominal voltage.

Installation is straightforward in most RC wiring layouts: place the unit between the battery pack and the receiver/servo distribution bus, verify correct polarity, and secure the regulator away from heat and moving parts. The neutral design of the unit means it does not impose specific connector requirements beyond matching your model's power leads.

For model builders and tuners who need a compact, straightforward regulator to protect servo and receiver electronics from battery voltage variation, the Futaba FURPS10 PS-10 offers a simple 5.2V 7A solution suitable for a wide range of electric RC setups.
