Do you support OEM and ODM switching power supplies?

Yes. OEM, ODM, design service and buyer label are offered. Output voltage, current limit, housing, connectors, display and communication interfaces such as RS485 can be customized after a specification review.

Which certifications do your power supplies carry?

Many standard models are listed with CE and RoHS marks. Please confirm the certificate scope for the exact model number before ordering, as compliance documents are model-specific.

What is the minimum order quantity?

Many standard models can be sampled from 1 piece. MOQ for customized or private-label projects depends on the specification and is confirmed in the quotation.

Which trade and payment terms are accepted?

Accepted delivery terms include FOB, CFR, CIF, EXW, FCA, DDP and express delivery. Accepted payment methods include T/T, L/C, D/P, D/A, PayPal, credit card, Western Union and escrow, in USD, EUR or CNY.

How should I size a switching power supply for my load?

As a practical rule, select a rated power 20–30% above the continuous load, add margin for motor or capacitive inrush, and apply the manufacturer's temperature derating curve if ambient temperature exceeds the nominal rating.
