DC-DC converter 48/24 V dc & 12/24 V dc

48/24 V DC, 5 A & 12/24V DC, 4A

  • Only 32 mm wide
  • Isolated output voltage
  • Wide input voltage range
  • 20% Power Reserve

Product description

Puls Dimension DC-DC converters have a high efficiency, very compact and mounted on a DIN rail.
The input voltage can for example. come from power supplies, batteries, solar panels, etc.. The output is galvanically isolated from the input. Typical applications are mounting at the end of a long cable to stabilize the voltage, convert one voltage to another or to isolate specific loads. Can also be used in conjunction with batteries to get a constant output voltage even though the battery voltage drops.
DC-DC converters are equipped with a soft start function which means that the stream gradually rises to the nominal value. This is avoided with high starting currents that can cause a voltage drop on the primary side and give boot problems.
A power reserve of 20% gives additional power resources at the temporary power peaks.
