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 reduces power costs

DY & DV Distribution TransFilters™

Harmonic mitigating transformers:
- DY for medium K-Factor loads
- DV for high K-Factor loads

- 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 drivers
- 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 (with Type DV)


Specialty Products

 PQI Product  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


240V motor loads

- Resolves failure problems that result when 230V and 240V motor are supplied by conventional 208V sources  
- Eliminates motor overheating


240V server loads

- Maintains voltage bandwidth required by rack mounted servers  
- Reduces server's load current by 15% and l2R losses by 33%

SYV 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
(l0 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 circuit for Mini-Z)
