Selection & installation notes
- The photographed PMH5A is marked 3–32 VDC input, while suffix 32 in the source coding chart is 5–24 VDC. Confirm the supplied revision and nameplate before selecting the input supply.
- The K-code description identifies AC/DC non-polar switching, while the selection table groups it under DC output. Confirm the exact permitted load before using this variant.
- The 380 V (440 V) wording is a family code description; it does not establish a universal voltage range for every PMH5A3 model.
- Choose the pinout, drive signal, load voltage/current and thermal conditions from the exact model document before PCB design. The housing does not remove the need to verify heat dissipation.
