SSR COMMAND MODE

The following power control modes are settable with the Firing.t parameter:
- Optimized BF:
modulation by means of changing the number of conduction cycles with zero crossing firing at each full wave with
optimum distribution of active channels (refresh time equals 100 half waves: 2.00 s at 50Hz, 1.66 s at 60Hz) to
minimize current draw peaks
- BF modulation by means of changing the number of conduction cycles with zero crossing firing at full wave
- HSC modulation by means of changing the number of conduction cycles with zero crossing firing at half wave
BF burst firing: this mode controls power on the load by means of a series of conduction cycles (ON) and non conduction
cycles (OFF). The ratio of the number of ON cycle to the number of OFF cycles is proportional to the value of power to be
supplied to the load. The period of repetition or cycle time is kept to a minimum for each power value.
The BF.Cycles parameter defines the minimum number of conduction cycles, settable from 1 to 20
HSC Half Single Cycle: this mode corresponds to a BF that includes half cycles of ON and OFF.
Used to reduce the flicker loads with short-wave infrared.
