DESCRIPTION
DESCRIPTION
12-12-35I DC Converter
This isolated series provides voltage conversion as well as input/output isolation, allowing the use of negative ground gear in positive or floating ground battery systems, or vice versa.
Using an isolated converter as a voltage stabilizer on 12- or 24-volt systems can solve conducted noise and interference problems on sensitive DC-powered communication, navigation systems, and DC microprocessor-based devices.
Features:
- Wide range of input voltage
- Precise output voltage regulation
- Reverse polarity
- Input fuse/output fuse
- Total input/output isolation, pos. or neg. ground
- Current-limiting, short-circuit-proof output
- Automatic resetting of the thermal shutdown
- High/low input voltage shutdown
- Polyurethane conformal coating on PC board
- Power ON light
- Rugged case designed for high-vibration applications
Specifications:
- Input Voltage: 10-16
- Max Input Amps: 56
- Output Voltage: 13.6
- Output Amps (Intermittent): 35
- Output Amps (Continuous): 20
- Case Size (H x W x D): 6 x 6.8 x 16.5 inches (15.2 x 17.3 x 41.9 centimeters)
- Weight: 12 lb. (5.5 kg)
- Output: 13.6 VDC (internally adjustable 12.6 -14.5) or 24.5 VDC (or specify)
- Ripple: 150 mV P-P maximum

- Isolation – Output/Chassis; Input/chassis: 250 VDC
Mechanical Specifications:
- Anodized aluminum heat sink case
- Front panel terminal block
- Heavy-duty mounting flange
- conformal-coated PC board
Options:
- Operation as battery charger or parallel redundant operation* – derate to continuous duty rating (contact factory)
- Extreme vibration mounting kit. (Information below)
Option: 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 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-vibration applications. It is available to fit all NEWMAR units from 2 to 70 lbs. Specify Kit L for units that weigh 2 -15 lbs. and Kit H for units that weigh 16 – 70 lbs.
