Spektrum VR5203 Dual Output Regulator

[SPMVR5203]
With your purchase, receive at no cost:
The VR5203 provides regulated voltage protection for up to two servo functions with two input ports and two output ports. This unique component eliminates the danger of higher voltage power systems to standard voltage servos by being placed in between the receiver and the servo needing regulation. This allows the rest of the system to work at a desired voltage.

Applications
Spektrum’s Dual Output Step Down Regulator is primarily designed for use with gyros in helicopters. Most brands of gyros/ tail rotor servos have voltage limits of 6 volts or less. The Dual Output Regulator installs between the receiver and the gyro in the rudder and gain channels and regulates the voltage to the gyro and tail rotor servo to a constant 5.2 volts. This allows the rest of the system to operate using higher voltage, typically 5-cell NiMH 6 volts or even 2-cell LiPo 7.4 volts, providing increased servo performance and response.

Additional Applications
We’ve also discovered that there are many other devices that are typically used in models which have voltage limits that the Dual Output Regulator is ideal for. Some brands of retract servos (including the JR791) have a limited voltage range and installing the Dual Output Regulator inline between the servo and the receiver allows the retract servo to function properly.

Important
The Dual Voltage Regulator is limited to 2 amps of continuous current. It is designed to install between the receiver and the gyro, operating the gyro and tail rotor servo only (or other control devices like a retract servo, electronic switch, etc.).

Features
  • 2 inputs provides the ability to run applications at lower voltages
  • 2 outputs distributes the load over two connectors to minimize drops in high current draw applications
  • Voltage input: 5.5 to 10 Volts
  • Continuous current: 2 Amps (3 Amps Peak)

It is not intended to be installed between the battery and the receiver to power the entire system.
