Delta Introduces Next Generation Open Frame Power Supply PJ Series with 200% Power Boost for Reliable Start-Up

Delta introduces the new generation PJ Series open frame power supplies, offering 100W and 150W models with 12V, 24V, and 48V output options. Supporting both AC (85–264 V_AC) and DC (120–373 V_DC) inputs, the Series is tailored for diverse industrial applications, from packaging and logistics to KIOSK machines and high-precision measurement equipment.

A crucial enhancement is its 200% power boost for up to 10 seconds, which sustains high startup inrush currents from motors and solenoids. This feature removes the uncertainty of accommodating peak power loads, eliminating the need to over-specify the power supply and ultimately delivering a more cost-effective design with superior space utilization.

Additionally, the PJ Series simplifies system integration by minimizing design complexity and optimizing space. Specifically, a built-in remote ON/OFF function provides integrated control from external systems, while the compact 27 mm low-profile open frame design fits easily into space-constrained installations. For operation in harsh environments, the Series features –40°C cold start capability and guarantees long-term reliability through conformal-coated PCBAs, providing a robust barrier against dust, moisture, and chemical contaminants within industrial machinery.

Furthermore, the Series meets major international safety standards, including IEC/EN/UL 62368-1, and is fully compliant with Japan’s PSE (DENAN) regulations, ensuring global reliability and streamlined entry into the Japanese market. With its outstanding efficiency, high power factor, and optional enclosed frame, the PJ Series is the premier choice for seamless integration across diverse power infrastructures.
