NewMar 12-12-3I DC-DC Power Stabilizer Converter 12V 3A

The NewMar 12-12-3I is a precision DC-DC power stabilizer designed to feed sensitive electronics with consistent, regulated voltage regardless of battery condition. This stabilizing converter provides continuous, precisely regulated 13.6V output over the entire range of a battery's usable voltage (10-16V input), preventing fluctuating input voltage that can cause equipment shutdown, diminished performance, or damage to sensitive circuitry.

Key Features:

• Operates electronics at optimal input voltage, even from nearly drained batteries
• Total input/output isolation virtually eliminates conducted line noise
• Permits connection of negative ground gear to positive or floating ground systems, or vice versa
• Boosts voltage to compensate for voltage drops in long wire runs from batteries
• Eliminates voltage drops during momentary high current drain, such as during engine start
• Can be modified for use as a battery charger for maintaining batteries at great distances from primary voltage source
• Rugged anodized aluminum heat sink case ideal for marine applications

Technical Specifications:

• Input Voltage: 10-16 VDC
• Input Current: 4A maximum
• Output Voltage: 13.6 VDC
• Output Current: 3A continuous, 3A intermittent
• Ripple: 150 mV peak-to-peak maximum
• Regulation: 1% line/load
• Switching Frequency: 40 kHz
• Efficiency: 85% typical
• Idle Current: Less than 100 mA (including power indicator light)
• Isolation: 250 VDC (output/chassis and input/chassis)
• Dimensions: 3.5" H x 3.5" W x 1.75" D
• Weight: 1 lb

Duty Cycle Ratings:

• Intermittent: 20 minutes maximum on time, 20% duty cycle with current limit set at approximately 105% of intermittent rating
• Continuous: 24 hours, 100% duty cycle
• Operating Temperature: 0-50°C (derate linearly from 100% at 40°C to 50% at 50°C; thermal shutdown at 70°C case temperature)

Construction:

• Anodized aluminum heat sink case
• Front panel terminal block for easy wiring
• Heavy-duty mounting flange
• Conformal-coated PC board for protection against moisture and contaminants

Available Options:

• Operation as battery charger (contact factory)
• Parallel/redundant operation capability (contact factory)
• Extreme vibration mounting kit for high-vibration vehicles (specify KIT-L for 2-15 lb units, KIT-H for 16-70 lb units)
• Non-standard output voltage (contact factory)

The 12-12-3I is ideal for marine, RV, and mobile applications where stable power is critical for navigation electronics, communication equipment, and other sensitive devices.
