Overview

PS3011-4820-0000 | Power supply 48 V, 20 A, 1-phase

Overview 1:

  • AC 100 - 240 V wide-range input
  • width only 125 mm, weight only 1.9 kg
  • 95.0% full load and excellent part-load efficiencies
  • 150% peak power, 1440 W for up to 4 s
  • 55 A high peak current over 10 ms for triggering fuses
  • Safe Hiccup overload mode
  • Active Power Factor Correction PFC
  • Negligible inrush current surge
  • Full power between -25°C and +60°C
  • Current-sharing function for parallel use
  • Remote control Output voltage
  • DC-OK relay contact
  • Shut-down input

The PS3011-4820-0000 is a 1-phase 48 V power supply with an output current of 20 A and an output power of 960 W. On the input side, the device features a wide-range input, active harmonic correction (PFC) and inrush current limiting.
The output operates according to the UI characteristic curve and switches to the safe hiccup mode in case of overload/short-circuit. The PS3011-4820-0000 power supply has an extra power feature 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 output voltage can be switched off by means of the shutdown contact.
The power supply is part of the PS3000 family and has a width of 125 mm.
The power supply unit is DNV-approved and can be used in shipbuilding, for example.
