Common Questions for DIN Rail Power Supplies

Answers to technical, lead time, and compliance questions commonly asked by procurement managers and electrical panel builders.

What certifications and compliance standards do Keldan DIN rail supplies meet?
All series manufactured by Yueqing Keldan Technology Co., Ltd. are CE compliant under EN 62368-1 safety standards and EN 55032 / EN 61000 EMC requirements. Full test reports and RoHS compliance declarations are provided before shipment.
What is your minimum order quantity (MOQ) and sample lead time?
Standard models such as DRP-240, EDR-120, NDR-240, and DR-15 can be ordered from 1 piece for evaluation. Small models like MDR-40 and MDR-60 have a standard MOQ of 10 pieces. Stock units ship within 48 to 72 hours; customized OEM production batches ship within 15 to 25 days.
How does Keldan guarantee long-term stability in extreme industrial environments?
Every power unit passes incoming 100% capacitor and semiconductor inspection, automated optical inspection (AOI) after surface mounting, and a compulsory 4-hour to 8-hour 100% full-load burn-in aging test to eliminate infant mortality before final packing.
Do you offer customized output voltages or private labeling?
Yes. As a verified Custom Manufacturer, our engineering department provides design-based customizations for non-standard DC voltages (e.g. 15V, 36V, 72V), customized terminal blocks, OEM silk-printed laser branding, and customized barcoding for automation system distributors.
