Delta PJ-150WDRA 150W Open Frame PSU

The Delta PJ-150WDRA Series Open Frame power supplies are engineered for high-performance AC-DC conversion in compact system designs. Featuring a slim 27mm low-profile form factor, these units enable seamless integration into space-constrained applications while maintaining efficient thermal performance through convection cooling. With universal AC input (85–264Vac) and high efficiency up to 93%, the PJ-150WDRA Series ensures optimized energy usage and reliable operation across a wide range of environments.

A standout feature of the PJ-150WDRA Series is its 200% Power Boost capability, allowing the power supply to deliver up to twice its rated output for short durations to support high inrush loads during startup. This reduces the need for oversizing the power supply, helping lower system cost and improve design efficiency.

Designed with advanced functionality, these open frame power supplies include built-in remote ON/OFF control, low inrush and leakage current, and robust protection features such as overvoltage, overload, short circuit, and overtemperature protection. Additionally, conformal coating protects internal components from dust and chemical contaminants, enhancing durability in harsh industrial environments.

With an operating temperature range of -40°C to +70°C, high power factor, and an MTBF exceeding 700,000 hours, the PJ-150WDRA Series delivers long-term reliability. Its open frame architecture provides maximum design flexibility, making it an excellent choice for industrial automation, instrumentation, and embedded system applications requiring compact, efficient, and dependable power solutions.
