SPECIFICATIONS: AIC300 SERIES |
|
All specifications are based on 25°C, Nominal Input Voltage, and Maximum Output Current unless otherwise noted. We reserve the right to change specifications based on technological advances. |
The AIC300 series open-frame AC-DC power supply delivers up to 300W with forced cooling and 180W with natural convection cooling in a compact 2 x 4 (50.8 x 101.6 mm) footprint, making it an ideal choice for space-constrained embedded and industrial systems
With high efficiency up to 94.5% and an ultra-low no-load input power under 0.3W, the AIC300 series supports energy-efficient designs and helps reduce standby power consumption
Additionally, equipped with a dedicated 12V fan output, Class I and Class II compatibility, and compliance with EN 55032 (Class B) EMI standards, it is engineered for high power density, quiet operation, and seamless system integration—providing a reliable power solution for industrial automation, test equipment, IPC, and telecom systems
