DC - DC Converters:
Standard & Isolated Series
Convert 20-50 VDC to 12 or 24 VDC output for powering communication/ navigation equipment, on negative ground systems. (see Isolated series, below for positive ground applications.) Ideal for powering voice, data and navigation transceivers in mobile and marine applications.
• 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*.
• Carries the CE mark
Same features as Standard Series, but with the additional capability of permitting connection of negative ground gear to positive or floating ground battery systems, or vice-versa. Many models may also be used as 12 or 24 volt stabilizers for highly input voltage sensitive equipment.
* Except 3 Amp. Model.
