What is the replacement power supply for the PSS55 series?

The PSS55 series of power supplies have been obsolete since 2013.  They have been replaced by the PSG240 series.  The PSG240E is the replacement for the PSS55A (120-240Vac input).   The PSG240F is the replacement for the PSS55C (480V input).  These are functional replacements and are intended to be used in conjunction with our S801/S811 or S801+/S811+ families of soft starters.   They are not physically identical.  But electrically and functionally equivelent.
