Electrical
Power Rating
Specify the required power by calculating secondary voltage multiplied by current. ex. 10 kVA. QT&E supports power ranges from:
1 VA - 1 kVA
1 kVA - 100 kVA
100 kVA - 1.5 MVA
Frequency
Define the operating frequency of your system (e.g., 50 Hz, 60 Hz, or custom). ex. 60 Hz. QT&E supports frequencies from:
50 Hz or 60 Hz
400 Hz
Phases
Choose between single-phase or three-phase configurations to match your application requirements; QT&E designs for both types. ex. 3PH.
Single-phase
Three-phase
Two-phase
Inputs & Outputs
Indicate the number, voltage, and current ratings for primary and secondary windings; QT&E accommodates a wide range of configurations and load profiles. ex. Input: 480V, Output: 120/240V split-phase.
1 V up to 600 V (up to 1.5 MVA)
(current or power rating needed along with voltage)
Isolation
Specify isolation requirements to ensure safety and signal integrity. ex. 4 kV isolation voltage. QT&E supports:
5 kV standard
Impedance
State the desired impedance to control voltage regulation and fault currents; QT&E provides custom designs to meet specific impedance values. ex. 4% (typical range: 2% to 8%)
Efficiency Standard
Choose an efficiency standard (e.g., DOE 2016, NEMA Premium); QT&E ensures compliance with the highest energy efficiency benchmarks. ex. DOE 2016 Compliant
Mechanical
Temperature Rise
Specify the allowable temperature rise above ambient for your application (measured in °C), typically based on insulation class or operational needs. ex. 80°C (standard for Class B).
Dimensions
Define the physical size constraints (height, width, depth) to fit your installation space. ex. H: 24 in, W: 18 in, D: 12 in
Enclosure
Indicate the required enclosure type based on environmental conditions, such as indoor, outdoor, or hazardous locations. ex. NEMA 1 (indoor use). Options include:
NEMA 1: Standard
NEMA 2
NEMA 3 + 3R: Protection from falling water.
NEMA 4 + 4X: Water proof, fully enclosed.
NEMA 6
Circuit Protection
Specify integrated circuit protection needs, such as fuses or breakers, for overload and fault conditions. ex. Primary & Secondary circuit breakers. Options include:
Circuit breakers
Fuses
Seismic Kits
Indicate if seismic bracing is needed to meet building codes in earthquake-prone areas. ex. Designed for Zone 4 seismic compliance
