SHV stands for Super High Voltage, and - as the term indicates - the Competition SHV operates with significantly higher voltages than previous 8.4V systems. The unit can cope with input voltages of up to 35V, which is then passed on to the servos in a redundant arrangement.

The Competition SHV is the latest member of the PowerBox product family, and has been developed to take into account the requirements of the latest generation of servos, with their ever-rising power and speed. SHV stands for Super High Voltage, and - as the term indicates - the Competition SHV operates with significantly higher voltages than previous 8.4V systems. The unit can cope with input voltages from 10 to 35V**, which is then passed on to the servos in a redundant arrangement. The advantage is obvious: for a given servo power the current carried by the servo cable is correspondingly reduced. For example, a servo drawing a current of 6A using 8.4V technology will only draw 2A using 25.2V technology and a 6S power supply.
The lower current drain results in the following scenarios:

For a given conductor cross-section, the lower current in the servo cable reduces the voltage drop to the servo. This in turn means more constant servo output power, and the servos operate with consistent torque and speed.
Much higher servo performance is possible, since currents increase by a lower factor.
For a given servo output it is permissible to use cable of reduced cross-section. in the case of large models this can result in a significant weight-saving.
Power supply batteries of significantly lower capacity and nominal current can safely be employed.
The unit is fitted with two redundant DC/DC converters for the two receivers, gyro, additional telemetry sensors and up to four servos; they generate a regulated voltage of 8.4V and can cope with loads of up to 10A. 

In terms of software the Competition SHV is based on the proven Competition SR2, and features all the usual PowerBox functions: 12-axis iGyro with optional speed compensation, servo-matching with Auto-Match function, door sequencer, input and output mapping and much more. The whole system can be set up using the high-resolution color screen, or alternatively from the transmitter if you are using PowerBox or Jeti equipment.

The UAV version operates using modified software: in this variant RX1 serves as “Master”, using channel 16 to switch between inputs RX1 and RX2. This can be used, for example, to switch between a conventional RC system and a Flight Controller. The Flight Controller is also powered by the Competition SHV.
