For new designs, National Instruments recommends the PS-15, PS-16, and PS-17 industrial power supplies.
The PS-5 is a DIN-rail-mountable 24 VDC power supply that provides 5 A of current and is rated for operation from -25 °C to 60 °C. You can wire two PS-5 supplies in parallel to provide up to 10 A. The PS-5 is recommended for industrial installations. The PS-4 is a DIN-rail-mountable 24 V power supply in FieldPoint packaging. The PS-3 and PS-2 are power supply “bricks” with a universal IEC power input. The PS-3 can also operate as a float charger for 12 VDC batteries. The PS-1 is a wall-mount power supply.
Note: Because the PS-4 and PS-5 are industrial power supplies, they are typically custom-cabled within industrial environments and therefore are not shipped with power cables.
