Power Supplies Heavy Duty Power Series

These super-rugged DC power supplies are ideal for powering 12 and 24 volt communication/navigation equipment onboard commercial vessels where reliability is essential. The proven linear circuit design provides pure noise free output and long service life.

Features

• Excellent Regulation and Ripple Spec: Output voltage maintained within 1% under all rated line and load conditions
  
• Polyurethane conformal coated PC board and corrosion resistant heavy duty aluminum case with integral shock mounts assures survival in hostile environments
  
• Heat generated by semi-conductors is extracted and dissipated by large heat sink fins for cool operation
  
• Protection: overvoltage, current limit; (set @ 105% of intermittent rating), thermal overload and input/output fusing
  
• Thermally activated cooling fan on "CD" units
