Phase
Outputs
The AL4016 phase outputs are synchronised to the zero cross
input signal over a frequency range of 45Hz to 65Hz. The
output phase trigger position is defined by the DMX512 input
level and modified by a square law curve. When driving a
thyristor load, this arrangement provides a linear variation in
the load power for a linear variation of the DMX512 input
level.
