ELAU PS-4 Series Technical Notes

The Evolution of PS-4 Architecture

The PS-4 power supply line was introduced alongside the original PacDrive C200/C400 controller generation in the late 1990s. Early units such as the PS-4/10/16/230/00 and PS-4/10/16/400/00 established the modular backplane power architecture that became standard across all PacDrive installations. These first-generation units operated on single-phase 230 VAC or three-phase 400 VAC input and delivered regulated 24 VDC and 5 VDC rails to the controller rack.

With the transition to PacDrive M and PacDrive 3 platforms under Schneider Electric branding (post-2006 acquisition), the PS-4 hardware entered a maintenance-only lifecycle. Schneider Electric continued to supply spare units through approximately 2015–2018, after which production was formally discontinued. Replacement migration paths include the Schneider Electric LMC058 and LMC078 motion controllers with integrated power management, but these require full software and wiring re-engineering. As a result, the majority of end-users operating PS-4-based systems continue to source original spare units to extend operational life.

Compatibility note: PS-4 units are backplane-specific. The 230 VAC and 400 VAC variants are not interchangeable without rewiring. The /00 suffix denotes standard firmware; regional variants exist with modified EMC filtering for specific market compliance.

PS-4 Full Catalog & Functionalities (SKU List)

The following models represent the verified production range of the ELAU PS-4 power supply series. Each unit is classified by input voltage, output capacity, and backplane compatibility.

Sourcing Hard-to-Find & Obsolete PS-4 Parts

For facilities operating PacDrive systems in regulated industries (pharmaceutical GMP, nuclear auxiliary, food safety), DriveKNMS can provide material certification documentation compatible with IQ/OQ validation requirements.

Quality Control for the PS-4 Range

Units that exhibit output deviation exceeding 2% from nominal, abnormal ripple, or thermal anomalies are quarantined and not dispatched. Test data is retained for each serial number and is available to customers upon request. This protocol is specifically designed for the PS-4's multi-rail output architecture and the known failure modes of this series (electrolytic capacitor degradation, MOSFET gate driver failure, and inrush limiter NTC thermistor wear).
