The Emerson/Artesyn/Astec LPS254-C is a 250 W enclosed switching power supply engineered for industrial applications requiring reliable, regulated DC output. This single-output unit delivers 15 VDC at 16.7 A and accommodates universal AC input from 85 VAC to 264 VAC or DC input from 120 VDC to 300 VDC across a 47 Hz to 440 Hz frequency range. Active power factor correction (>0.90) ensures efficient mains utilization and reduces harmonics to meet EN61000-3-2 compliance.
