ITEM #: 1438454Convert 20-50 VDC to 12 or 24 VDC negative ground output for powering communication/navigation equipment, on negative ground systems. (see Isolated series for positive ground applications.) 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.
