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. Except 3 Amp.
- Carries the CE mark
Isolated series
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.
Input range:10-56 VDC; positive, negative or floating
ground.
Output: 12 or 24 VDC, 3 to 35 amps.
