AC LINE TRANSIENT VOLTAGE RUGGEDNESS
The ACS120 switch is able to sustain safely the AC line transient voltages either by clamping the low en-
ergy spikes or by breaking over under high energy shocks, even with high turn-on current rises.
The test circuit of the figure C is representative of the final ACS application and is also used to stress the
ACS switch according to the IEC 61000-4-5 standard conditions. Thanks to the load, the ACS switch sus-
tains the voltage spikes up to 2 kV above the peak line voltage. It will break over safely even on resistive
load where the turn on current rise is high as shown on figure D. Such non repetitive test can be done 10
times on each AC line voltage polarity.
