AC line transient voltage ruggedness
The ACS108-6S switch is able to withstand safely the AC line transients either by clamping
the low energy spikes or by breaking over under high energy shocks, even with high turn-on
current rises.
The test circuit shown in
is also used to test the ACS switch according to the IEC 61000-4-5 standard conditions.
Thanks to the load limiting the current, the ACS108-6S switch withstands the voltage spikes
up to 2 kV above the peak line voltage. The protection is based on an overvoltage crowbar
technology. Actually, the ACS108-6S breaks over safely as shown in
ACS108-6S recovers its blocking voltage capability after the surge (switch off back at the
next zero crossing of the current).
Such non-repetitive tests can be done 10 times on each AC line voltage polarity.
