Wieland Electric Unveils Compact WIPOS PSU3 Three-Phase Power Supply for Control Panels
Engineering teams designing modern industrial control panels constantly battle against shrinking physical footprints, thermal management limits, and unpredictable load spikes. To solve these persistent integration challenges, Wieland Electric has officially rolled out its PRO LINE WIPOS PSU3 series. This advanced three-phase power supply lineup delivers a high-density, highly efficient power delivery architecture tailored explicitly for demanding factory automation, smart infrastructure, and machinery applications.
Available across a versatile power spectrum ranging from 120 W to 960 W, the PSU3 series offers both 24 VDC and 48 VDC options alongside an adjustable output voltage stretching up to 29 VDC. This voltage adjustability gives system integrators a practical tool to instantly combat line voltage drops across lengthy industrial wiring runs. Furthermore, the inclusion of push-in terminals significantly slashes cabinet assembly times while ensuring vibration-resistant mechanical connections under harsh operational environments spanning from minus twenty-five to seventy degrees Celsius.
A standout engineering achievement of the PSU3 series is its exceptional transient response and heavy load handling capability. The unit boasts a 150% power boost for seven seconds, allowing control systems to effortlessly absorb high inrush currents generated by capacitive equipment and heavy motor startups without forcing designers to specify an oversized, costly power unit. Operating at an impressive up to 95% efficiency, the power supply drastically curtails internal thermal dissipation within sealed cabinets, preserving component lifespans and reducing the need for auxiliary cabinet cooling.
Grid reliability and electrical protection have also been given top priority in this release. The hardware features comprehensive dual-stage surge protection utilizing metal oxide varistors alongside integrated gas discharge tubes to guard against severe grid transients. An intelligent hiccup mode automatically manages short-circuit events to completely prevent thermal runaways, while strict adherence to Class B EMC standards guarantees seamless coexistence with sensitive PLC and safety automation hardware. Certified to comprehensive international benchmarks including IEC EN 61010/62368 and major UL directives, the new Wieland power supply is ready for immediate deployment in global manufacturing, renewable energy frameworks, and material handling systems.
