Why Use a Mini Servo Power Distribution Box?

Essentially the same as the Green ECO version but this red version also has a selectable input voltage to your receiver (see below diagram) as well as a OPTO isolated CDI ignition switch designed for petrol (gas) powered aircraft.

When using a large number of servos or a few high power digital servos the current needed to power these servos can be high, for example one single 16kg digital servo can draw up to 2.5A so you can see that it doesn't take many servos before very high current is needed to power all your servos. Receivers are not designed to handle such high current and you stand a real risk of damaging your receiver due to this high current and therefore loosing your large and expensive pride and joy.

The Mini Servo Power Distribution Box routes the power needed by your servos away from your receiver and through it's printed circuit board which is designed to handle currents as high as 30A making your system a lot safer.

The Mini Servo Power Distribution Box also allows you to use 2 separate batteries to power your receiver and servos giving you added safety should one battery fail while in flight.

It also allows for a very neat installation of up to 16 servos, 2 servos per channel.
Should the"ON/OFF" switch fail or become disconnected in flight, the system will fail to"ON"

How to select the voltage to the receiver (B)

CDI Ignition connection and indicating LED's (G,H,I,J)

Features

• Use 2 batteries to eliminate crashes should one battery become open circuit.
  The Power Box draws from both batteries.
• 8 channel plus 1 CDI ignition cut port
• Up to 16 servos, 2 servos for each channel
• OPTO isolated CDI ignition cut circuit to eliminate interference caused by CDI ignition.
• Independent 5V linear voltage regulator which provide a separate pure working power supply to the receiver
• 5x LED's indicated the boards working status (6 statuses)
• In event of switch failure, unit fails to"ON"
• Includes 3" servo extensions cables to connect your receiver to the Servo Power Distribution Box
• Easy and convenient location of receiver
• Supplied with ON/OFF switch
• Supplied with rubber mounting grommets and screws

Please Note

If using 2 batteries, please make sure they are identical with regards to:
type, number of cells, capacity , and most importantly that they are the same voltage before connecting them both to the Servo Power Distribution Box as any differences can result in a large current transfer between the two batteries until their voltages become equal, this high current could damage either the wiring and/or the batteries themselves.
Check to make sure you have selected the correct jumper position (B) for the voltage for your receiver before connecting your batteries.
