• 95.4% 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
• 55 A peak current over 25 ms for triggering fuses
• Active power factor correction (PFC)
• Active filtering of input transients
• Negligible input inrush current surge

• Shutdown input
The PS3031-4820-0000 is a 3-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 power factor correction (PFC) and inrush
current limiting.
The PS3031-4820-0000 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. 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 110 mm.
