The AA10U-048L-120S is a 10-watt isolated DC-DC converter module designed for applications requiring regulated power conversion from wide input voltage ranges. It accepts an input voltage range of 18-75V DC and delivers a single 12V output at 0.830A maximum current, with a total power rating of 10 watts. The module features a compact 1.0" × 2.0" × 0.38" unencapsulated case, operates over an ambient temperature range of -40°C to +75°C with no derating, and provides 1500V DC input-to-output isolation. Key electrical characteristics include ±1.0% voltage tolerance, ±0.5% line regulation, 82% typical efficiency, and 380 kHz switching frequency, with short-circuit protection via continuous power cycling and overvoltage protection via Zener clamp. This converter is ideal for industrial control systems, telecommunications equipment, and embedded applications where reliable isolated power conversion and wide input voltage tolerance are essential.
