4.4 Voltage range
4.4.1 Programmer Output / Supply Voltage range
The PPM3 Module has been designed so that it can be powered from an external 9.0 to 12.0V DC
regulated power supply via the jack socket (J6) or directly from a Target System running at +5.0V DC.
The programmer is capable of generating a controlled supply voltage to the Target System of
between 3.0V and 5.0V at 300mA, but this is only possible if the programmer is powered from an
external 9.0 to 12.0V power supply,
