DC-Transformer 251-24-SD

Converter can be used in various applications

Key figures

  • ultrawide input voltage range: 12 ... 36 VDC
  • very high efficiency: up to 98%
  • peak input voltage: 37 VDC
  • output voltage / max. output current: 24.0 VDC / 11.0 ADC

Applications

The 24VDC-power supply works with input voltages between 12V to 36V. Due to its buck-boost technology, it is permanently short-circuit proof an voltage dips for 100ms in 24V-systems as defined in EN50155 are easily covered. For new designs its successor 257E-24-SD with an extended power range should be used.

Features

  • non-isolated step up and step down converter
  • very low input ripple
  • continous no load and short circuit proof
  • for ambient temperatures of -40°C up to +85°C
  • thermal shutdown at +90°C
  • for passive loads only
  • integrated EMI input and output filter
  • no derating of power
  • heatsinking metal plate
  • robust design
  • unipolar output voltage
  • non-isolated output
