These supplies are ideal for applications requiring reliable 24, 32V or 48 VDC bulk power.



TDK-Lambda (San Diego, CA) has introduced the RFE1000 series; a new 1kW single-output AC-DC power supply in an ultra low profile (only 1.61” high) 1U package for stand alone or distributed power architectures (DPA). These supplies are ideal for applications requiring reliable 24, 32V or 48 VDC bulk power. Features include:

  • Output voltage adjustment of +20 percent and -10 percent.
  • A universal input of 85 to 265 VAC.
  • Efficiency of up to 88 percent that minimizes heat dissipation.
  • Up to 8 units can be connected to form an N+1 redundant power system.
  • Built in ORing diodes.
  • Variable-speed cooling fans.
  • Operating temperature range from 0° to +70°C
  • A power density of 10.5W/in3 with dimensions of 12 x 5 x 1.61 inches.
  • Overvoltage, overcurrent and overtemperature protection.
