The Allen-Bradley 1398-PSM-125C is a 1398 Ultra Plus Series power supply module designed for industrial applications, requiring a three-phase input power of 100-240V AC with an input frequency of 47-63 Hz. This module offers an output voltage of 100-340V DC, achieving 325V DC with a 230V AC input, and features a nominal AC input current of 82A with a maximum inrush current of 100A. Designed for robust performance, it provides a peak DC output current of 450A and a continuous DC output current of 100A, with a peak shunt power capacity of 40 kW and continuous shunt power of 1.2 kW. Operating efficiently between 0-55 °C with a non-condensing humidity range of 5-95%, it supports an installation altitude of up to 1500 meters, derating above this level, ensuring reliable use across various environments. The module's protective features include self-protection and a dissipative shunt regulator that efficiently discharges DC bus capacitors and absorbs rotational energy, making it compatible with multiple servo drives and motors. Installation requires placement within a grounded conductive enclosure, minimizing inductance by positioning high-power drives nearby, and necessitates a setting free from vibration and contaminants with ample ventilation and ease of access.
