NEWMAR DC CONVERTER 32-24-3, 32V TO 24V DC, 3AMP PEAK
Standard 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*.
* Except 3 Amp. Models.
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 (see page 13)
Input range:10-56
VDC; positive, negative or floating ground.
Output: 12 or 24
VDC, 3 to 35 amps.
Options
24 VDC output (see specs at below)
Operation as battery charger or parallel redundant operation* derate to
continuous duty rating (contact factory)
Extreme vibration mounting kit. (See below)
* Except Model: 32-12-3.
