DESCRIPTION

The PJT-12V100WBAA is a 100W open frame power supply designed for industrial applications, delivering a regulated 12V DC output at 8.33A from a universal AC input range of 90–264 Vac. The unit features a compact standard industrial footprint of 127 × 76.2 × 31 mm (3" × 5") with convection cooling, enabling efficient thermal management and operation across -10°C to +70°C. Key technical characteristics include ±0.5% line regulation, ±1.0% load regulation, low leakage current of 0.1 mA, and high reliability with MTBF exceeding 700,000 hours per Telcordia SR-332. The power supply incorporates multiple protection mechanisms including overvoltage (latch mode), overload/overcurrent (hiccup mode auto-recovery), over-temperature protection, and short-circuit protection, along with galvanic isolation of 3.0 kVac between input and output. This design is ideal for industrial automation, telecommunications, and embedded systems requiring stable, isolated DC power with robust protection and long operational life.
