Wieland Electric Enhances Power Density with New WIPOS PSU3 Series
The demand for reliable, high-density power delivery in modern industrial control panels has reached a critical juncture. Wieland Electric’s newly launched PRO LINE WIPOS PSU3 series addresses these complexities by providing a robust three-phase power supply that balances high efficiency with a flexible power boost capability. Designed to mitigate common engineering hurdles—such as space constraints and erratic load profiles—this series serves as an essential component for automation systems and critical energy infrastructure.
At the heart of the PSU3 series is an impressive 95% efficiency rating, which serves to minimize energy waste and operational heat generation, thereby reducing the necessity for auxiliary cooling within confined enclosures. A standout feature for system integrators is the unit's ability to deliver a 150% power boost for seven seconds. This capacity is vital for managing the start-up surges typical of capacitive equipment, allowing designers to size power supplies based on nominal rather than peak load requirements. With output power ranging from 120 W to 960 W across 24 VDC and 48 VDC models, the series provides the modularity required for diverse applications.
Reliability remains a cornerstone of the PSU3 design. To protect sensitive downstream electronics, the unit incorporates dual-stage surge protection utilizing MOV and integrated gas discharge tubes (GDT). Furthermore, the power supply features an intelligent hiccup mode to prevent thermal damage during short-circuit events and exceeds Class B EMC standards, ensuring stable performance in high-interference environments. From a deployment standpoint, the use of push-in terminals significantly accelerates wiring time, while an adjustable output voltage of up to 29 VDC compensates for potential voltage drops over long cable runs.
These units are engineered for global compatibility, featuring wide three-phase input ranges and comprehensive certifications including IEC EN 61010/62368 and UL standards. Whether integrated into PLC systems, medical instrumentation, HVAC controls, or EV charging stations, the WIPOS PSU3 offers a compact footprint that does not compromise on power density. By integrating real-time monitoring through DC-OK LED indicators and relay contact outputs, Wieland Electric has ensured that this series meets the evolving data and diagnostic needs of Industry 4.0.
