DC-DC Converters
Standard Series
|
Convert 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.

charger or parallel redundant operation* – derate to continuous duty rating
(contact factory)
*Except Model: 24-12-3
Extreme
vibration mounting kit
The Extreme Vibration Mounting Kit
is available to protect NEWMAR power converters from the extreme stresses of
shock and vibration when mounted on high–vibration vehicles.
The kit (pictured here) replaces the
standard vibration kit provided with the unit and fits into the unit's mounting
flange to act as a "super shock absorber" for electronics in high-vibe
applications. It is available to fit all NEWMAR units from 2 to 70 lbs. Specify
KIT–L for units which weigh 2–15 lbs. and Kit–H for units which weigh 16-70 lbs.
