External EMC filters
The need to use a filter to obtain emissions conducted on the line during power-on of SCRs with phase angle trigger depends on
the applications.
It is important to connect the power filter as close as possible to the solid-state power unit.
We recommend a filter with the following characteristics:
Voltage Load voltage
Current Max. current on load
Rated frequency 50/60Hz
Common mode attenuation >35dB@100KHz >60dB from 150KHz to 1.5MHz
Differential mode attenuation >50dB@100KHz >60dB from 150KHz to 1.5MHz
The following are two commercial filters tested in single-phase applications:
Model Load 230V Load 400V

POWER (SOLID-STATE RELAY)
Load type AC 51 resistive or low inductance loads
AC 55b short wave infrared lamps (SWIR)
AC 56a transformers, resistive loads with high temperature coefcient
Trigger mode
PA - load control via adjustment of ring phase angle
ZC - Zero Crossing with constant cycle time (settable in range 1-200sec)
BF - Burst Firing with variable cycle time (GTT) optimized minimum.
HSC - Half Single Cycle corresponds to Burst Firing that includes ON and OFF half-cycles.
Useful for reducing icker with short-wave IR loads (applied only to single-phase resistive or
3-phase 6-wire open delta loads).
Feedback mode V: Voltage feedback: proportional to RMS voltage value on load to compensate possible
variations in line voltage.
I: Current feedback: proportional to RMS current value on load to compensate variations in
line voltage and/or variations in load impedance.
W: Power feedback: proportional to real power value on load to compensate variations
in line voltage and/or variations in load impedance. You have to calibrate each time you
change feedback mode.

for applications in which you can set a minimum power output limit (ex: Lo.P = 10%) by also
limiting the lamp power variation speed with gradient limit (ex: G.out = 20%, PS.TM = 20s).
Under these conditions, the nominal currents shown on the table can be raised up to the
values indicated for AC51 type loads.
