Overview

Product overview

Key product information and technical features.

The PS-16 supplies DC power to supported NI measurement and control equipment. Its DIN-rail mounting and spring-clamp connections distinguish it from a desktop laboratory power supply.

NI lists the PS-16 in its CompactDAQ and CompactRIO power-accessory tables. Select the supply and connection accessories against the specific controller or chassis requirements rather than assuming that every device in either platform uses the same power connection.

24–28 VDC output range with a 10 A rating.
DIN-rail mounting for industrial installation.
Toolless spring-clamp terminals for field wiring.
20% power reserve for fluctuating loads; NI permits continuous use of the additional current below 45 °C ambient.
Model-specific side-mount and shared panel-mount accessories are listed by NI.
