Re: [mh] CM11A

[Han A. <h_...@ho...>]

Hi Neil,

The 120 kHz frequency is generated by the Pic (The PWM output). As the
clock for the Pic is derived from a crystal, the 120KHz is very
accurate.
A optocoupler sepeates the Pic from the mains. The actual driver
consists of a few transsistors and a LC network.

Regards,
Han Alink
