Common Specifications |
Construction |
Core |
Flat laminations (E&I) of high grade grain oriented silicon steel for a long, stable life. |
Encapsulant |
TPR rubber (also known as TPV, TPE) |
|
|
Much higher dielectric strength and lower water absorption than older materials such as epoxy, neoprene, or polychloroprene. |
|
|
Minimal swelling in the presence of hydrocarbons, unlike neoprene, polychloroprene, etc. |
Encapsulation process |
Injection molding for maximum consistency of encapsulation, yielding exceptionally low leakage currents. Vacuum drawing prior to injection prevents air pockets inside. A far superior process to compression or transfer molding, or pouring. |
Winding |
Magnet wire on a plastic bobbin, specifically designed to electrically isolate the primary and secondary windings for maximum safety. |
Connector pins and sockets |
Tin plated for corrosion resistance |
Primary cables |
Cable is AWG #8 (8,3 mm2) Type C TPR for maximum reliability |
Secondary cable |
Cable is AWG 2/12 (3,3 mm2) |
Material compatibility |
Transformer body, cables, and connectors are all molded of TPR for perfect bonding. |
Watertightness |
Amerace® transformers are designed and manufactured to operate submerged in water indefinitely. |
Electrical |
Insulation Level |
5000 V RMS |
Insulation Resistance |
|
Minimum 7500 Megohms (tested hot with 15 kV DC) |
|
|
Typical 150,000 Megohms |
|
|
Much higher than that required by FAA |
Open Circuit Voltages |
|
Less than 3 times the full load RMS value in all cases, generally much lower, when tested with sine waves. |
Efficiencies |
85% to 95% depending on the power rating |
Power Factor |
> 0,97 for all |
Ratio |
Flat response load curves for constant lamp brilliancy and long life |
Testing |
|
All units (100%) are hipotted and their ratio confirmed |
|
|
All ratio testing done with the appropriate frequency, 50 Hz or 60 Hz, for precision. No "conversion factors" used. |
Environmental |
Operating Temperature Range |
-55°C to +65°C |
Contaminant resistance |
Suitable for areas contaminated with most oils, aircraft fuels, soil acids and alkalis, and deicing fluids. Resistant to UV exposure and ozone. |
Installation Options |
All types, including above ground, in concrete or other non-metallic pits, in metal cans, or direct buried. |
