The IsoBox Medical Grade Isolation Transformers
For Safer Use of Medical Electronics in Patient Care Areas

Introducing the IsoBox SERIES, a new product line of Medical Grade Isolation Transformers with low noise and low EMR (Electro-Magnetic Radiation). Four standard models are available in attractive aluminum cases for floor or wall mounting.

For Patient Care Areas*, our IsoBox Series offers added safety when using electronic or electromedical devices. By connecting such apparatus to the IsoBox, you will benefit from the added protection and you may rest assured that you will be in full compliance with the legal requirements of maximum 100 µA leakage current and isolation as stipulated by the NEC (National Electrical Code) and UL (Underwriters, Laboratories) safety standard UL2601.1.

You can also realize some savings in your purchasing budget when buying standard commercial grade printers, video monitors, computers and other devices and connect them to our IsoBox, instead of paying for higher priced medical grade components. Our IsoBox will take care of the required maximum leakage current requirements for Patient Care Areas*.

There are two basic series available. The U.S. series operates at 117V/60Hz for U.S. and Canadian installations. The International series is designed to operate in North America as well as overseas and in South America.

Using our own design and manufacture of the toroidal power transformers for the IsoBox, we can achieve a voltage drop of only 6% for the 300VA rating and smaller for the larger power ratings. The toroidal transformer inside the IsoBox is virtually hum free, generates very low EMI (Electro Magnetic Interference) and runs quite cool, also at rated full load. Computer and video monitors can be sensitive to EMI as are many other electronic devices.

North American/Domestic Medical Hospital Grade  Isolation Transformer
For Safer Use of Medical Electronics in Patient Care Areas


The Medical Grade Isolation Transformers have both low mechanical noise and low EMR (Electro-Magnetic Radiation). We have two standard formats, available in attractive white aluminum cases for floor, wall, chassis and cart installation. Typical applications include installation of computers, video monitors, surveillance cameras, test and measurement instruments, printers, clinics, doctor’s offices, or whenever safe operation of electronics equipment requires low leakage current levels.

This line of enclosed isolation transformers offers all the advantages of the toroidal constructions such as low weight, low magnetic strayfield, low mechanical noise, low losses, high efficiency and cool operating temperature. The low height of the toroidal transformer allows the enclosure to have a low profile for easy installation in a modern office environment.

The enclosures are made of sturdy aluminum with a white finish. Other colors are optional. On all the North American/Domestic models, the secondary neutral conductor is grounded. To order models without the secondary neutral bond to ground, please call the factory.
