Engineering Selection Recommendations
KMS40-5 is a suitable substitute for RAC40-05SA based on matching enclosure type, number of outputs, voltage ratings, current, power, application (medical), features, efficiency, operating temperature, mounting type, mechanical footprint, regulatory approval, and RoHS/REACH compliance. Both devices carry 60601-1 certification for medical use and support universal input.
Frequently Asked Questions (FAQ)
Q1: What parameters must match for direct substitution of an AC/DC converter in medical applications?
A1: Substitution requires matching enclosure type, number of outputs, input voltage range, output voltage and current, output power, application type, features, mechanical package, operating temperature range, efficiency, and regulatory approvals.
Q2: Are the mechanical dimensions and mounting type of KMS40-5 and RAC40-05SA identical?
A2: Both parts share the same 7-DIP Module, 5 Leads package, through hole mounting type, and similar size/dimensions, enabling mechanical interchangeability.
Q3: Does the KMS40-5 satisfy medical certification and compliance requirements?
A3: KMS40-5 carries 60601-1 approval as required for medical applications, in addition to other listed certifications.
Q4: Is there any difference in output regulation between the two models?
A4: RAC40-05SA lists line regulation of ±0.5% and load regulation of ±1%. KMS40-5 specifies line regulation at 0.5% and load regulation at 1%.
Q5: Are both RAC40-05SA and KMS40-5 RoHS and REACH compliant?
A5: Both models are RoHS compliant and REACH unaffected based on provided data.
