Delta PJ-100WDRA Open Frame Power Supplies

The Delta PJ-100WDRA Series Open Frame power supplies are engineered for high performance and durability in demanding environments. Featuring a low-profile 27mm design, these units are ideal for applications requiring compact integration without sacrificing power. A key advantage is the built-in 200% Power Boost capability, allowing the power supply to handle high inrush loads during startup without the need to oversize the system.

With universal AC input (85–264Vac), high efficiency up to 93%, and excellent power factor correction, the PJ-100WDRA Series ensures energy-efficient operation across a wide range of applications. Additional features include remote ON/OFF control, low inrush and leakage current, and comprehensive protection functions such as overvoltage, overload, short circuit, and overtemperature protection.

Built for long-term reliability, the series incorporates conformal coating to protect against dust and chemical contaminants, operates in temperatures from -40°C to +70°C, and offers an impressive MTBF of over 700,000 hours. Its open frame design enables flexible system integration, making it ideal for industrial automation, instrumentation, and embedded system applications.
