Power supplies for 24 V and 48 V DC

Power supplies for 24 V and 48 V DC

The power supply PS3031-4820-0000 is a 3-phase, 48 V DC power supply with an output current of 20 A and an output power of 960 W. On the input side, the device has a wide range input, an active power factor correction (PFC) and an inrush current surge regulation.

The PS3031-4820-0000 has an extra power with a maximum output power of 150% for 4 seconds and can precisely trigger fuses with short-term peak current. The power supply belongs to the PS3000 family and has a width of 110 mm. 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 a shut-down contact directly.
