2 and 4 Advanced Burst fire control
For this type of control it is necessary to use a “Non zero-crossing” SSR.
In order to minimise power fluctuation during the modulation period, the “advanced Burst fire” SSR
output firing mode uses:
· A complete number of cycles for firing
· A complete number of half-cycles for non-firing

For a percentage less than 66%, SSR output firing takes place as in
the “Burst fire” mode. (parag. 9.b)
For a setpoint greater than 66% in “Advanced Burst fire” mode:
· The non-firing time is constant at one half-cycle
· Firing takes place over whole cycles.
In a ‘short-wave infrared’ application, ‘advanced Burst fire’ firing
mode reduces the brightness of the infrared elements and thus
minimises annoying visual flickering.
