The PowerBox 12 is a small, compact dual power supply with integral mechanical switch.

Like the PowerSwitch, this unit employs a high-quality switch with floating contacts, which creates a one hundred percent switched connection even when subjected to severe vibration. All components are soldered to a single circuit board. The cables are fitted with adhesive-lined heat-shrink sleeves to protect them from mechanical damage where they exit the case, enabling the unit to withstand extremely powerful vibration.

The PowerBox 12 does not feature an integral voltage regulator, but can naturally be used with LiPo and LiFePo batteries provided that the receiving system incorporates servos and receivers approved for HV use.

A tri-colour LED indicates the switched status of the PowerBox 12.
