Newmar 32-12-25 DC Converter

32-12-25 DC Converter

Convert 20-50 VDC input to 12 VDC negative ground output for powering communication and navigation equipment on negative ground systems. (See Isolated Series for positive ground 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 the long life of components
• Polyurethane conformal coating on PC boards and corrosion-resistant anodized aluminum cases with heavy-duty shock mounts assure survival in hostile environments
