Q1: Why is the current limited to 5A for your 12V Class 2 adapters?
A: To comply with the UL 1310 Class 2 standard, the output of a 12V circuit must not exceed 60W (5A x 12V). This limitation is what classifies the device as safe for simplified building wiring and reduced shock risk.
A: Yes. For high-stability applications, our Desktop 12V UL Class 2 Power Adapter is available with the 3-pin C14 inlet to ensure a robust safety ground connection for your hardware.
A: Absolutely. Upon request, we provide the UL File Number and full compliance reports for our UL 1310 Certified 12V DC Supply series to ensure your project passes all North American safety inspections.
