For Radio Controlled Model Aircraft where the modeler uses high-voltage servos but would like to use a lower cost servo for non-critical flight controls/systems. This device will allow the modeler to use less costly servos for throttle, as an example. Where a less costly servo could be used in the model.
This device will drop-down the voltage to 5 volts, at a current rate of 3.5 amps. Power supply input voltage can range between 4.5V to as high as 27 volts D/C while the output is regulated at fixed level of 5 volts.
Using this device will permit the modeler to use a power supply (ex. LiPo) in the range higher than what the proposed servo can withstand. It will work with all digital servos as well as analog servos.
Note: Follow radio equipment manufacturer instructions on the correct signal rates for analog servos. This is necessary even if this converter is not used.
The signal output from the receiver to the servo is unaffected and does not route through the DC converter in any way. Only the "+" and "-" DC power is routed through the converter.
The length of any servo extension wire, of the modeler's choosing, can be used as needed for a particular installation.
My own model aircraft had a throttle servo that had failed, due to its voltage being exceeded. The result is my creating a device I could use on the throttle servo to regulate the voltage being supplied to it.
I will be listing other DC to DC converters with 1 amp ratings for smaller installations because the converter itself is slightly smaller due to the less current rating.
