Selection & installation notes
- The PMS2 technical table does not establish PMS6D or PMS2K ratings. Confirm exact input suffix and footprint before PCB layout.
- Choose semiconductor protection and suppression for actual load inrush and fault current. Derate above 40 °C and for dense PCB populations.
- Zero-cross AC versions are unsuitable for phase-angle control. OFF leakage can energize a load; isolate supply before maintenance.
