The Signamax 48 Volt Industrial Power Supplies have been developed to operate in harsh environments, providing clean 48 Volt DC power to equipment that operates in severe conditions. These power supplies are the solution for outdoor environments, transportation roadside systems, shop floors, and other harsh environments where temperature extremes exist.

Input power can be either AC or DC, over a wide voltage range, and the included DIN-rail mount in the molded case makes mounting quick and easy. These power supplies are perfect for powering media converters and PoE switches in harsh environments or other devices requiring 48 Volt DC power.

 

 

  • Built-in DIN-rail mount for hassle free installation
  • EN50082-2 Heavy Industry Level, Criteria A standard supported
  • UL508 approved for industrial control equipment
  • TUV EN60950-1 approved
  • 48 V DC power output with overvoltage protection to 68 V
  • Overload protection up to 150% of rated power with constant current limiting & automatic recovery
  • Extended operating temperature range 14°F to 140°F (-10°C to 60°C)
