DDA Series

Non-isolated, Single & Dual Output DIN Rail DC-DC Converters 250W – 500W

The DDA DIN rail mount, non-isolated step-down converters are ideal for creating additional high current output voltages from a single output 24V or 48V AC-DC power supply. This highly efficient, compact series accepts a very wide DC input and has a wide output adjustment range with a choice of single or dual output models.

Main Features

  • 250W Single Output, 325W and 500W Dual Output Power Levels
  • High Efficiency up to 95%
  • Wide Input Range – 9 up to 53V
  •  Wide 3.3 to 24V Output Adjustment
  • Narrow 36.5mm Width
  • Convection Cooled

Benefits

  • High Power Density
  • Less Waste Heat
  • One Part For Multiple Applications
  • Accommodates Non-Standard Voltages
  • More Space Available For Other DIN Rail Devices
  • Easy To Cool In End System
