VSBU-150-24

The VSBU-150-24 is an open frame AC/DC converter manufactured by CUI Inc., designed for chassis mounting in industrial and commercial applications. This single-output power supply delivers a maximum of 150W at 24Vdc and 6.25A. It accepts a wide universal input voltage range of 90 to 264Vac across 47 to 63Hz frequencies, making it suitable for global deployment without regional modifications. The unit achieves up to 88% efficiency at full load and incorporates active power factor correction to meet modern energy standards.

Engineered for reliability, the VSBU-150-24 offers robust isolation ratings of 4,242Vdc between primary and secondary circuits, alongside comprehensive protection features including over-voltage, over-current, and short-circuit safeguards. It operates within a temperature range of 0°C to 70°C with derating and maintains an estimated mean time between failures of 100,000 hours under standard conditions. The compact mechanical footprint measures 127.0mm x 76.2mm x 35.6mm, facilitating integration into space-constrained enclosures while maintaining chassis mount stability.

Compliance certifications include UL/cUL, CB, CISPR-22 Class B, and FCC Part 15 Class B, ensuring adherence to international safety and electromagnetic interference regulations. The design supports non-condensing operation at 5% to 95% relative humidity and withstands storage temperatures from -40°C to 85°C. This converter is optimized for OEM systems requiring stable DC power with minimal ripple and fast transient response characteristics.
