Phase Angle (Pa) Mode - gefran GRM-H 15 Configuration And Programming Manual

In the example shown in the figure, this parameter is
= 2.
HSC Half single cycle
This mode corresponds to Burst Firing, which handles
on/off semi-cycles.
It is useful to reduce the flickering of the filaments

5.6.1.2. Phase Angle (PA) Mode

This mode manages the power on the load by
modulating the trigger angle θ:
Resistive load
Example of operation in HSC mode at 33% and 66% power
819XX_MAN_GRM-H_11-2022_ENG_pag. 61
with short / medium wave IR lamp loads, with such
loads, to limit the steady state current with low power,
it is useful to set a minimum power limit (e.g. Lo.P =
10%)
Example:
if the power to be transferred to the load is 100%, θ
= 180°, or if the power to be transferred to the load is
50%, θ = 90°
