Overview

PS3031-2440-0000 | Power supply 24 V, 40 A, 3-phase

Overview 1:

  • 3AC 380-480 V wide-range input
  • Three built-in input fuses
  • 95.3% full load and excellent part-load efficiencies
  • Width only 110 mm, weight only 1.5 kg
  • 150% peak power, 1440 W for up to 4 s
  • 110 A peak current over 25 ms for triggering fuses
  • Active power factor correction (PFC)
  • Active filtering of input transients
  • Negligible input inrush current surge
  • Full power between -25°C and +60°C
  • Option of current sharing for parallel connection
  • Controllable output voltage level
  • DC-OK relay contact
  • Shutdown input

The PS3031-2440-0000 is a 3-phase 24 V power supply with an output current of 40 A and an output power of 960 W/1440 W.

On the input side, the device features a wide-range input, active power factor correction (PFC) and inrush current limiting.

The PS3031-2440-0000 features an Extra Power output with a maximum output power of 150% over 4 seconds and is able to trigger fuses precisely with a short-term peak current. The output voltage can be switched off by means of the shutdown contact. A DC-OK LED, an overload LED and a potential-free relay contact monitor the status of the output voltage.

The power supply is part of the PS3000 family and has a width of 110 mm.
