Product Details

The NewMar 32-12-50 is a high-performance DC-DC converter designed to convert 20-50 VDC input to 13.6 VDC negative ground output, ideal for powering communication and navigation equipment on marine, RV, and mobile applications. This rugged converter delivers 50 amps intermittent (20 minutes max) or 40 amps continuous output with exceptional reliability.

Key Features:

  • Precision voltage regulation within 1% under all line and load conditions
  • Large heat sink fins extract and dissipate heat for cool operation and extended component life
  • Polyurethane conformal coating on PC boards for protection in hostile environments
  • Corrosion-resistant anodized aluminum case with heavy-duty shock mounts
  • 40 kHz switching frequency with 85% typical efficiency
  • CE marked for compliance

Comprehensive Protection Circuits:

  • Current limiting with automatic thermal shutdown at 70°C case temperature
  • Short circuit proof design
  • Reverse polarity protection
  • Overvoltage protection

Technical Specifications:

  • Input Voltage: 20-50 VDC
  • Output Voltage: 13.6 VDC (internally adjustable 12.6-14.5 VDC)
  • Output Current: 50A intermittent / 40A continuous
  • Ripple: 150 mV peak-to-peak maximum
  • Regulation: 1% line and load
  • Isolation: 250 VDC output/chassis and input/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)

Construction:

  • Powder-coated aluminum heat sink case
  • Front panel terminal block for easy connections
  • Heavy-duty mounting flange with shock mounts included
  • Conformal coated circuit boards for harsh environment protection

Optional extreme vibration mounting kits are available for high-vibration vehicle applications. The converter can also be configured for battery charger or parallel redundant operation when derated to continuous duty rating.
