描述

SPD48601 is a 60W switching power supply designed for DIN rail installation in industrial automation applications. It provides a regulated 48VDC output at 1.25A nominal current with universal AC input (100-240VAC, 47-63Hz) and supports both AC and DC input ranges (85-264VAC or 90-375VDC). The unit features comprehensive protection including short-circuit fold-forward protection, overload protection at 110-150%, and overvoltage protection with varistor-based surge suppression. Key performance characteristics include ±0.5% line and load regulation, ±1% output voltage accuracy, 89% typical efficiency, and 50mVpp ripple and noise. The supply operates reliably across -40°C to +71°C ambient temperature with derating above 61°C, includes a DC ON green LED indicator and Power OK output, and meets CE, TUV, and cULus certifications. This makes it ideal for critical automation systems requiring compact, reliable power conversion with DIN rail convenience.
