Linear DC Power Module SCHROFF PSK 312 7–39 W, AC/DC Linear Regulator

SCHROFF PSK 312 is an AC/DC linear regulator power module that provides a stable DC supply with output power in the 7–39 W range. The compact design is intended for integration into chassis or system racks and for use in industrial and embedded electronic systems where low-noise, precision regulation is required. The module supports linear regulation topology to minimize output ripple and transient disturbances, helping sensitive analogue and mixed-signal circuitry maintain performance under varying input or load conditions.

Advantages

The SCHROFF PSK 312 delivers low-noise linear regulation with predictable behaviour across its rated power range. Its compact form factor simplifies installation in standard chassis or rack-mounted assemblies while providing thermal stability suitable for continuous operation. The module's linear design avoids high-frequency switching artifacts, contributing to cleaner power for sensitive components and easier filtering requirements in system design.

How to use

Install the SCHROFF PSK 312 into the designated slot or mounting location in the chassis following the manufacturer's mechanical guidelines. Connect the AC input and the regulated DC output per the system wiring diagram, ensuring correct polarity and adequate conductor sizing for the expected load current. Provide recommended chassis or forced-air cooling as part of the system thermal design. Verify output voltage and load behaviour at initial power-up and during commissioning to confirm stable regulation before connecting sensitive downstream circuitry.

Usage recommendations

For reliable long-term performance, pair the module with proper heat dissipation measures in the enclosure, avoid heavy capacitive loads on the output without appropriate decoupling, and perform initial verification under representative load and input conditions to confirm low-noise performance and thermal stability.
