Newmar DC-DC Converters Standard Series

Supply your device with the right power

The Newmar DC-DC Converters Standard Series converts 20-50 VDC input to 12 or 24 VDC negative ground output for powering communication/navigation equipment, on negative ground systems. Ideal for powering voice, data and navigation electronics in marine applications.

Newmar DC-DC Converters Standard Series 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 aluminium 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
  
• Overvoltage protection
  
• Carries CE mark
