Overview 1:

  • Width only 110mm, weight only 1.5kg
  • 95,2% Full load and excellent partial load efficiencies
  • 50% Extra Power, 1440W for up to 4s
  • 100A Peak current for 10ms for easy fuse tripping
  • Active filtering of input transients
  • Negligible low input inrush current surge
  • Full power between -25°C and +60°C
  • Current sharing feature for parallel use
  • Remote control of output voltage
  • DC-OK relay contact
  • Shut-down input

The PS9771-2440-0000 is a DIN-rail mountable DC/DC converter with an input voltage of 475 to 750 V DC which provides a floating, stabilized and galvanically separated SELV/PELV output voltage of 24 V DC with 40 A.

It contains various functions and can be used for the following purposes:

Large power reserves of 150% support the starting of heavy loads such as DC-motors or capacitive loads. In many cases this allows the use of a unit from a lower wattage class which saves space and money.

The integrated output power manager, the near zero input inrush current make installation and usage simple.

Diagnostics are easy due to the DC-OK relay, a green DC-OK LED and the red overload LED.
