Frequently Asked Technical & Sourcing Questions
Open frame power supplies depend on either natural convection cooling or forced-air cooling provided by system chassis fans. Most datasheets provide two ratings: convection-cooled wattage (typically 50-70% of peak) and forced-air wattage with specified cubic feet per minute (CFM) air movement.
Yes. We furnish comprehensive factory technical documentation, official CE, CB, UL, EAC test reports, and factory warranty declarations for every batch supplied.
We support sample engineering verification and small-batch production runs starting from 1 to 5 pieces depending on specific wattage models, allowing engineering teams to validate prototypes without excessive inventory commitment.
