24-12-3 DC Converter
Convert 17-32 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 the rating
- The 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
Numerous Converter and Load Protection Circuits:
- Current limiting
