The VTC1050-48 from Analytic Systems is a Buck DC-DC Converter that converts an input voltage of 130 - 390 V to an output voltage of 48 V. It provides an output current of up to 110 A. This converter offers power factor-corrected input stages and increased efficiency over the previous auto-switching technology, ejecting input voltage dead spots and allowing the voltage converter to run continuously. It incorporates heavy input and output filtering to reduce electromagnetic interference (EMI) to extremely low levels and prevent radio interference from degrading the performance. It features an LED status indicator panel, an input circuit breaker, thermal shutdown, current limiting, reverse polarity connection protection, and an output short circuit shutdown with automatic recovery. This IP67-rated step-down converter exhibits an expanded operating temperature range and integrates shock and vibration protection for high reliability during operation. It is available in a wall-mount package that measures 42.7 x 20.8 cm and is ideal for marine, military, and telecommunication applications.
