Pacific’s unique master/slave configuration allows up to ten 62.5 kVA mainframes to be paralleled in the field. Any mainframe may be designated as the master. A failed unit is automatically disconnected from the power grid providing unmatched mission reliability.
Pacific MS-Series is a family of High Performance Line Conditioners/Frequency Converters that provides highly flexible, yet reliable, AC power ranging from 62.5 to 625 kVA. Using field-proven double conversion methods, the MS-Series offers unmatched power quality without sacrificing size or efficiency.
Input AC power is rectified to DC by a special input power supply section. This minimizes input current distortion and prevents the load power factor from reflecting back onto the utility line. The DC is then converted back to AC by a high frequency, solid state, pulse-width modulated switchmode inverter under the control of a highly stable digital oscillator. The result is exceptional system performance with maximum reliability.
The rugged reliability of the MS Series and the ease with which two or more MS cabinets can be paralleled to create high power solid state conversion AC power systems has resulted in its wide spread use for production test, certification test and R&D applications in Commercial as well as Avionics Industries.
