FSP100-RAAK3 100W 24V AC-DC Power Supply for Thermal Printer and Industrial Equipment

The FSP100-RAAK3 is a 100‑watt AC‑DC power supply module specifically designed for thermal printer applications and industrial systems. It delivers a nominal output of 24.0V DC at 4.17A (100W typical average power) and supports a peak output of 230W (18.0V at 12.8A) to handle repetitive burst loads required by thermal printing. The unit features a universal AC input range of 90‑264VAC (47‑63Hz) with active power factor correction (0.85 min at 230Vac full load). Compliant with CoC Tier2 efficiency standards, it achieves an average efficiency of 89% minimum at 25%/50%/75%/100% load and 79% minimum at 10% load, while no‑load power consumption is as low as 0.15W max. Output ripple and noise is limited to 300mVpp (tested with 47µF//0.1µF capacitors, 20MHz bandwidth). Protection features include over‑voltage protection (latch type, 26‑30V), foldback current limiting (18.0V min at 12.8A for 10 sec), and short‑circuit protection with auto recovery (<8.0A after 60 sec). Transient load response is <5ms for 40% to 80% load steps, and holdup time is 20ms min at 120Vac. The power supply operates from 0°C to 40°C with free air convection cooling and meets rigorous safety and EMC standards: EN55032/CISPR22 Class B, FCC Part 15 Class B, EN55024, IEC61000‑4‑5 Level 3, and IEC61000‑4‑4 Level 2. It carries approvals such as CB, TUV, CE, and CEC, with a leakage current ≤0.75mA at 230Vac/60Hz. With a compact mechanical footprint of 146.2 x 75.2 x 39 mm and a standard C14 input connector, it is ideal for space‑constrained applications requiring reliable 24V power.
