The AEE01B18-LS is a 15-watt isolated DC-DC converter module designed for industrial and telecommunications applications. It accepts an input voltage range of 9 to 36 VDC and delivers a regulated 12 VDC output at 1.25 A, with 1500 VDC minimum input/output isolation and auto-restart short-circuit protection. The converter operates over a wide temperature range of -40°C to +71°C without derating, achieving 84% efficiency at 12 V input, with output voltage tolerance of ±2.0%, line regulation of ±0.5%, and load regulation of ±1.0%. The module features a compact 1" × 2" encapsulated package with a switching frequency of 300 kHz and output noise/ripple of 120 mV. This converter is well-suited for industrial automation, instrumentation, test and measurement, and telecommunications systems requiring reliable isolated power conversion in harsh environments.
