Rugged COTS and Custom Transformers
Rugged COTS and Custom Isolation Transformers
This series of isolation transformers are designed for use in Naval and other platforms requiring COTS transformers with robust construction that meet MIL specifications.
Available standard models include the following:
| COTS MODEL NAME | POWER | INPUT VOLTAGE | OUTPUT VOLTAGE | FREQUENCY | NOMINAL WEIGHT (LBS) | NOMINAL SIZE (INCHES) |
|---|---|---|---|---|---|---|
| TR60K-440(D)-120/208 | 60 KVA | 440 VAC 3∅ Delta | 120/208VAC 3∅ WYE | 60 Hz | 510 LBS | 22"H x 17.5"L x 8"W |
| TR100K-440(D)-120/208 | 100 KVA | 440 VAC 3∅ Delta | 120/208VAC 3∅ WYE | 60 Hz | 860 LBS | 22"H x 17.5"L x 9.5"W |
| TR300K-440(D)-120/208 | 300 KVA | 440 VAC 3∅ Delta | 120/208VAC 3∅ WYE | 60 Hz | 2000 LBS | 22"H x 23"L x 15"W |
The above transformers are designed with a lower flux density so that the core will not saturate during MIL-STD-1399 testing, considering the combined effects of high input voltage with low input frequency.
All of the transformers in this series feature a 220 degree Celsius Class “H” insulation system, a 2500 VAC hipot test, and UL varnish. They have been tested to a variety of military standards for shock, vibration, temperature and humidity.
Other voltage and power ratings are available. Please contact us for more specific information for your project.

Nova Electric’s transformers are all designed and built in house to exact customer specifications from 250W to 500+KW and beyond. Only the highest quality materials are used, and customers can specify special wire or hardware requirements. Each transformer produced is made to a UL 220°C class H insulation system with HPT insulated copper magnet wire and Nomex insulation. To protect against moisture, each transformer is varnished in a vacuum impregnation system and then finished with a durable black top coating. Each transformer also undergoes a very thorough inspection process that includes hi-pot and continuity testing, as well as visual inspection. Transformers are available in freestanding, rack mount (with or without chassis slides and shock bull pin receptacles,) or sealed portable enclosures appropriately ruggedized for military or harsh environment applications. Connectors and other miscellaneous options can be ordered as per unique customer requirements.
For More Details:
Due to the “built to order” nature of these accessories, we encourage any interested customers to forward us complete details of what they require – electrical and environmental specs, space and weight constraints, quantity required, etc. – so that we may propose the most effective solution. Customers are encouraged to e-mail complete specifications or call to discuss such applications with a project engineer so that we can tailor our solution to your specific needs.
