DC-DC Converters Standard Series Convert 20-50 VDC to 12 or 24 VDC negative ground output for powering communication/navigation equipment, on negative ground systems. Ideal for powering voice and data transceivers in mobile applications. Features - Excellent Regulation: Output voltage maintained within 1% under all line and load conditions within rating. - Heat generated by semi-conductors is extracted and dissipated by large heat sink fins that maximize air contact for cool operation and long life of components. - Polyurethane conformal coating on PC boards and corrosion-resistant anodized aluminum case with heavy duty shock mounts assure survival in hostile environments. - Numerous converter and load protection circuits: Current limiting; automatic thermal shutdown; short circuit proof; reverse polarity and overvoltage protection.
