AC/DC Power Supply
RMT-8
Overview
The RMT-8 is a compact AC to DC power supply in a rugged enclosure making it ideal airborne or vehicle applications. The RMT-8 features full electronic protection using an innovative power factor correction design, high efficiency and low output noise. The built-in fan provides sufficient airflow for operationwithout de-rating up to 50°C ambient temperature.
