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
| PQI Product |
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
| 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 |
| 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) |
