Mission-Critical Facilities

PQI has a number of unique products specifically suited for data center and other mission critical facilities. These products offer maximum engineering flexibility, ultra-high efficiency, and superior power quality outcomes.

    Standard Products

    Description Benefits within Mission-Critical Facilities
    EY (e-Rated®) Ultra-efficient transformer – Low first cost
    – Ultra-low excitation (core) losses reduce power costs
    DV Distribution TransFilterTM  Harmonic mitigating transformer – Reduces power costs
    – Reduces penalty losses due to harmonic currents
    – Reduces transformer heating and A/C loading
    – Reduces THDv to less than 5% at nonlinear loads or motor drives
    – Reduces losses in the loads, thereby reducing A/C requirements
    – Improves switch-mode power supply’s ‘ride-through’ capability
    – Balances primary phase currents
    – Assures system compatibility with sensitive electronic loads
    – Capable  of developing 12-, 18-, 24-, and 36-pulse primary systems

    Specialty Products

    Typical Application Additional Benefits within Mission-Critical Facilities
    DD Motor drive loads – Provides isolation from upstream transients
    – Eliminates phase-to-ground voltage excursions at the motor drive
    MY 240V motor loads – Resolves failure problems that result when 230V and 240V motors are supplied by conventional 208V sources
    – Eliminates motor overheating
    SY 240V server loads – Maintains voltage bandwidth required by rack mounted servers  
    – Reduces server’s load current by 15% and l2R losses by 33%
    SVY 240V & 120V server loads  – Provides optimum voltage for 240V & 120V server loads  
    – Reduces 240V server load current by 15% and l2R losses by 33% when compared to a conventional 208V source
    RV Remote load centers – Eliminates zero-sequence harmonic current on the neutral conductor of the feeder circuits that supply remote load centers
    Z Filter
    (I0 Filter & Mini-Z)
    High K-Factor loads (l0 Filter)
    Load-end of branch circuits (Mini-Z)
    – Reduces neutral-to-ground voltages to <4V at nonlinear loads (<1V for Mini-Z)
    – Increases general purpose (K 1) transformer capacity by up to 54%
    – Protects upstream neutral conductor 
    – Increases feeder and bus capacity
    – Balances feeder and bus phase currents (& branch circuits for Mini-Z)
