Medical Approved
Patient contact rated
2500 Vac breakdown
Faraday shielded
transformers
TheUL544Seriesproductlisted
have met the stringent require
ments for Patient Contact rating
as defined by Underwriters Laborato-
ries, Inc., under UL544; STANDARD for
SAFETY - MEDICAL and DENTAL
EQUIPMENT. All models are recog-
nized and listed accordingly under File
E50975 of the U.L. Component Recog-
nition Program. These units are based
upon standard reliable product families
which are specifically modified to meet
the severe demands of UL 544. All
models utilize a Faraday shielded
power transformer which holds leakage
at 10A maximum. Effective isolation
techniques give these units a higher
than required voltage breakdown rating
of 2500 Vac (min).
Applications
High voltage breakdown and low
leakage current make these units
ideally suited for medical and patient
contact applications. Portable ultra-
sound scanners, electrocardiograph
monitoring systems and microproces-
sor controlled blood analyzers are just
a few of the many applications utilizing
UL 544 units. Although Underwriters
Laboratories maintains strict require-
ments to ensure the safety of such
equipment, UL 544 recognized units
are not limited to these applications.
These units are also being incorporated
in computer interface systems, copy-
ing machines (color analysis), and
other applications requiring a high
degree of isolation.
