In order to upgrade to the latest IEC 62368-1:2018 (Ed 3.0) standards, Delta will remove the varistor component (position “Z1”) from the PJT-40W and MDS-040APS series. Comprehensive testing and verification of the results have been conducted to ensure that all customers can expect consistent, high-quality product performance after these design changes.
For more details, please refer to the latest specifications on the DeltaPSU website.
