Powerbox DigiSwitch MPX/JR (7.4V Version)

Product description

PowerBox Systems have been producing the DigiSwitch since 2004, and it still remains the smallest and lightest voltage regulator available commercially.

The DigiSwitch is an excellent choice for any application where there is no space for mechanical switches and heavy batteries. In conjunction with modern LiPo or LiFePo battery technology, the DigiSwitch represents an effective weight-saving measure, and also provides additional security with its integral voltage monitor and electronic switch, which is both totally reliable and vibration-resistant.

The on / off switching process is initiated by pressing the push-button twice. The micro-controller monitors the sequence, and turns the electronic switch on or off if the procedure is valid. This eliminates any danger of operating the switch accidentally, and produces a connection which is resistant to vibration.

The switch is a latching type, i.e. it stores the last switched state. This means that the system always remains switched on even if there is a brief interruption in the circuit at the battery end.

A further safety feature of the DigiSwitch is the integral voltage monitor: the tri-colour LED indicates the battery’s state of charge in three stages. The voltage monitor can be set to suit all commonly used battery types: 2S LiPo, 2S LiFePo, 5S NiMH or 4S NiMH.

The DigiSwitch reduces the input voltage to 5.9 V (optionally 5.3 V), and therefore supplies the correct voltage for standard 6 V servos.

Two different connector systems are available at the battery end: Uni or MPX types. The MPX version is supplied as standard with two receiver connecting leads.
