FSP120-AHAN3 120W AC-DC Power Supply / Adapter

The FSP120-AHAN3 is a 120‑watt AC to DC power supply (adapter) from FSP, designed as a reliable power solution for IPC systems, embedded systems, POS systems, industrial control devices, and other ITE applications requiring stable 12V DC output. As a compact power supply unit (PSU) with a C14 socket, this FSP120‑AHAN3 model operates from a wide input voltage range of 90‑264Vac (47‑63Hz) and delivers 12Vdc at 10A (120W continuous). It meets high efficiency standards: ≥88% efficiency compliant with DOE Level VI and ≥89% efficiency compliant with CoC Version 5 Tier 2, ensuring low power consumption and reduced heat generation. The adapter includes comprehensive protection features: over voltage protection (OVP set at 19V), short circuit protection, over current protection (OCP), over temperature protection (OTP), and brown‑out protection. With a low no‑load power consumption ≤0.5W, touch current ≤0.25mA, and an MTBF of 300,000 hours at 25°C (SR332), it offers high reliability. The FSP120‑AHAN3 is also equipped with a PFC circuit, meets EN55032 Class B EMC standards, and has an operating temperature range from 0°C to 40°C (100% load) derating to 55% load at 70°C. This 12V 10A power supply is ideal for use as a computer power supply for industrial PCs, server auxiliary power, POS systems, and embedded applications.
