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 up to 20 kHz
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
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)
600V up to 240 kV
(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
5 kV up to 200 kV (custom)
Efficiency Standard
High efficiency is vital to minimize energy losses in power transmission, particularly in long-distance applications.
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
Notifications
Define any notification features required, such as indicator lights, alarms, or digital displays for system status. ex. Green (Power On), Red (Fault) indicator lights with an audible alarm for overload
