Features:
- S1 variant identity: the suffix remains part of the complete model
- Legacy CENTUM record: Yokogawa includes the base model in official system documentation
- Evidence-led matching: label and cabinet data control the power-supply decision
PW404 S1 is retained as a complete Yokogawa power-supply variant rather than being collapsed into the base code.
The absence of exact public electrical data makes the installed label the authoritative source for source and load matching.
Separating this variant from other PW-series supplies prevents a family-name similarity from becoming an unsupported interchange claim.
Apter Power can compare the complete PW404 S1 label, connector layout, host cabinet record, condition, and quotation requirements.
