Product Details

The MilCOTS 3-Phase MPFCQor Power Factor Correction module is an essential building block of an AC-DC power supply. Used in conjunction with one of SynQor’s matched 3-Phase AC line filters and a limited amount of stabilizing capacitance, this MPFCQor will draw well-balanced and low-distortion sinusoidal currents from each phase of a 3-Phase AC input. It is designed to comply with a wide range of military standards and is manufactured in the United States.

Operational Features

• Large-module form factor
• 5.0 kW continuous rating at 80 °C baseplate temperature
• Semi-regulated output: 400 Vdc
• Compatible with Military Standard 60 Hz, 400 Hz & var. freq. systems
• Meets military standards for harmonic content
• Drives pulsed output loads without passing transients back to the
input (requires adequate capacitance; see pulsed loads section)
• Minimal inrush current
• Balanced phase currents
• High power factor (0.999 at 60 Hz / 5.0 kW)
• Minimal external output capacitance needed
• Supports full load current during startup ramp
• Additional input filters available to meet full EMI
• N * 5.0 kW power levels when paralleled
