Procurement Notes

Verify the specific datasheet version to confirm exact physical dimensions and terminal configurations before integration. Ensure that the chassis mounting requirements align with the design specifications. Confirm that the operating frequency matches the system's 50Hz or 60Hz standard. Validate insulation ratings against environmental conditions. Cross-reference the part number with official manufacturer documentation to avoid substitution errors.

Selection Notes

Select this model when a 187.5 VA capacity is required for chassis-mounted installations. Consider the dual secondary voltages if multiple low-voltage rails are needed from a single source. Evaluate the 3000Vrms isolation requirement for safety-critical applications. Compare physical footprint constraints against available space. Assess thermal management needs based on the continuous load current of 25.0A per secondary.
