PXIE-4112

The PXIe-4112 is a high-density, 2‑channel isolated programmable DC power supply in a single PXI Express slot. Each channel delivers up to 60 V, 1 A, and 60 W, with a combined module power of 120 W. Designed for automated test systems, it integrates output disconnect relays, 4‑wire remote sense, and hardware sequencing, providing accurate, stable power for aerospace, defense, automotive, and component test applications.

Description

Model Nomenclature

PXIe stands for PXI Express high‑speed modular instrumentation bus. 41 denotes the programmable power supply series. 12 indicates a 2‑channel, 60 V, 1 A configuration with isolated outputs.

Usage and Maintenance Instructions

Installation and Configuration

Insert the module into a 3U PXIe chassis slot and secure the front panel. Connect load and sense wires to the Phoenix Contact terminals, ensuring correct polarity and wire gauge (12–24 AWG). Connect auxiliary power if required. Power on the chassis; the system automatically detects the module. Use NI‑MAX to set voltage/current limits, enable remote sense, and configure trigger parameters. Develop test sequences using LabVIEW or other supported environments.

Daily Maintenance

Operate in a clean, dry, well‑ventilated environment within 0 °C to 55 °C. Inspect connectors and cables periodically for wear, dirt, or damage. Avoid over‑torquing screw terminals to prevent damage to the connector housing. Ensure adequate airflow around the module during continuous operation. When not in use, power off the chassis and disconnect all cables. Store in an electrostatic‑protected bag in a dry location.

Safety Notice

Do not exceed the maximum voltage (60 V), current (1 A), or power (60 W per channel) ratings to prevent permanent damage. Follow ESD procedures when handling the module. Disconnect all power before installing, removing, or servicing the module. Use only insulated tools when making connections. Dispose of the module in accordance with local electronic waste regulations at end‑of‑life.
