Overview 1:

  • 3AC 380 - 480 V wide-range input
  • Also specified for 2-phase operation
  • 95.4% full load and excellent part-load efficiencies
  • width only 65 mm, weight only 870 g
  • 150% peak power, 720 W for up to 4 s
  • Active Power Factor Correction PFC
  • Active filtering of input transients
  • Full Power between -25°C and +60°C
  • Extremely low input inrush current surge

The PS3031-4810-0001 is a 3-phase 48 V power supply with an output current of 10 A and an output power of 480 W.
On the input side, the device features a wide-range input, active harmonic correction (PFC) and inrush current limiting.
The PS3031-4810-0001 power supply 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. 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 65 mm.
