Spektrum Voltage Protector
Part Number: SPM1600
Many Electronic Speed Controllers (ESC's) which use a BEC (battery Elimination Circuit) will only supply enough voltage to run 2-3 servos yet many people seem to ignore this and run 4, 5 or even 6 servos with a BEC!
In a lot of today's speed controllers the circuitry is such that the motor will get priority and with the power of servo's and electric motors used in today's model aircraft, this can lead to a momentary voltage drop to the receiver. Resulting in what appears to be interference. Many people are simply running too many servos with a BEC'd ESC. What appears to be a 'glitch' could easily be as simple as a voltage drop on the BEC supply to the receiver.
To overcome this Spektrum has released a simple plug in device that stores an 'electrical charge' so if the voltage drops below a certain level the device discharges its voltage helping to 'smooth-out' the voltage level and maintain strong radio reception.
Installation is as simple as plugging it into a spare channel on the receiver.
- For Spektrum DSM or standard systems
- Prevents voltage drops to receiver
- Plugs into any open channel slot
NOTE ON ESC's: If your model has 4 or 5 servos and a voltage equalling 3S Li-Po or more, it is strongly recommended to run the ESC 'OPTO ISOLATED' (without BEC) using a U-BEC or receiver battery to power the radio and servos. This can be easily done by removing the RED wire from the ESC's radio plug then using said U-BEC or receiver battery.
