Product Details

The NewMar 32-12-25 is a high-performance DC-to-DC converter that transforms 20-50 VDC input power to a stable 13.6 VDC negative ground output, ideal for powering communication and navigation equipment on marine vessels, RVs, and other mobile applications. With a 25-amp intermittent rating (20-amp continuous), this converter delivers reliable power conversion with 85% efficiency and minimal ripple.

Key Features:

  • Precision voltage regulation maintains output within 1% under all line and load conditions
  • Large aluminum heat sink fins extract and dissipate heat for cool operation and extended component life
  • 40 kHz switching frequency provides efficient power conversion with low electromagnetic interference
  • Output voltage adjustable from 12.6-14.5 VDC to accommodate various equipment requirements
  • Polyurethane conformal coating on PC boards protects against moisture and corrosion
  • Heavy-duty shock mounts and anodized aluminum case ensure durability in harsh marine and mobile environments

Comprehensive Protection Systems:

  • Current limiting protects against overload conditions
  • Automatic thermal shutdown at 70°C case temperature prevents damage from overheating
  • Short circuit proof design allows safe operation even during output faults
  • Reverse polarity protection prevents damage from incorrect wiring
  • Overvoltage protection safeguards connected equipment
  • CE marked for European compliance

Technical Specifications:

  • Input Voltage Range: 20-50 VDC
  • Output Voltage: 13.6 VDC (adjustable 12.6-14.5 VDC)
  • Output Current: 25A intermittent (20 minutes max, 20% duty cycle), 20A continuous
  • Ripple: 150 mV peak-to-peak maximum
  • Regulation: 1% line and load
  • Efficiency: 85% typical
  • Isolation: 250 VDC (output to chassis, input to chassis)
  • Idle Current: Less than 100 mA including power indicator light
  • Operating Temperature: 0-50°C (derate linearly from 100% at 40°C to 50% at 50°C)
  • Dimensions: 6.0" H × 4.7" W × 14.0" D
  • Weight: 7.5 lbs

Construction:

  • Powder-coated aluminum heat sink case for superior thermal management
  • Front panel terminal block for easy wiring access
  • Heavy-duty mounting flange with integrated vibration dampening
  • Conformal coated circuit boards for enhanced reliability

Optional extreme vibration mounting kits are available for high-shock applications such as emergency vehicles or off-road equipment. This converter can also be configured for battery charging or parallel redundant operation when derated to continuous duty specifications.

quick and easy!

I was able to order this battery with no problems.

best prices

Also wanted a resonator pipe, but couldn't seem to find it here.

Nice quick interface

Easy order.

Thanks
