Power supply
The mains has to be provided by pins 1 and 3 of the J7 connector (pin 2 can be linked up to
earth). The voltage input range must be within 185 ÷ 265 Vrms at 50 Hz.
The digital section is provided by means of a circuit based on the VIPER12 to obtain 15 Vdc
and a positive voltage regulator L7805 to obtain 5 Vdc.
The VIPER12 can be left out by removing J9. In this case, 15 Vdc have to be provided on
J10 (positive on pin 1).
