Signal Transformer: Your ONE SOURCE for ALL your Magnetics needs
The largest product offering for Standard and Custom Power Transformers and High Frequency Magnetics.
Signal Transformer has designed and manufactured standard and custom power transformers and magnetics since our
founding in 1959 in Brooklyn, NY. Utilizing our global manufacturing, engineering, and logistics capabilities and the resources
of our parent company Bel Fuse Inc. (NASDAQ: BELFA & BELFB), Signal Transformer is positioned to support your needs
wherever you are located. At Signal Transformer, we are committed to providing the highest grade magnetics for customers
who demand total reliability, on-time delivery, and competitive pricing. Year after year, engineers and buyers consistently
choose Signal Transformer as their preferred source for magnetics. Since 1959, we’ve led the magnetics industry with
innovation, creativity, and reliability by:
Pioneering and perfecting direct sales of off-the-shelf transformers and chokes to the user
Maintaining a large inventory - over 1,000 different models of chokes and transformers in stock from 1 VA to 10 KVA,
available off-the-shelf any time / every time
Offering customized Stocking Programs, VMI and JIT
Providing annual contract programs with competitive volume pricing
Speedy service in obtaining the latest safety agency certifications including UL, CSA, VDE, IEC, EN, TUV, BSI, and CE for
special customer needs
Design and Construction
Because we pride ourselves on listening to what our customers say, we at Signal have always been able to develop
innovative, quality products to meet changing requirements. Our success has been built by continuously addressing all major
concerns such as RoHS, flammability, voltage breakdown, high temperature materials, as well as design criteria such as:
Smaller size and weight per VA (See our MPI, SHE, HPI & M4L series)
Better performance through improved volumetric efficiency
Superior suppression of radiated magnetic field (See our STP, IF, LPI series)
Large VA, 3 Phase Transformers (See our 3PH series)
High Frequency Magnetics designed for your specific application (see our H series)

TOROIDAL POWER TRANSFORMERS
Power in the Round 100 VA to 2000 VA
1. STP transformers having dual secondary windings may be ordered by
specifying the power range, output voltage and current requirements. (A
250VA transformer with two 24V secondary windings = STP-0250-2024.
A 1200 VA transformer with two 120V windings = STP-1200-2120.) Where
dissimilar or multiple output configurations are required, please contact
Customer Service for additional information. In all cases, a serialized part
number will be assigned to the final product label.
2. The dimension profiles depicted for each VA range are for standard
transformers with 2 x 115V output configurations. Dimensions of transformers
with multiple outputs, dissimilar outputs or ELV outputs may vary.

As shown on the schematic diagram the DU line incorporates dual primaries and secondaries. All four windings are identically rated at 0/104/110/120 V. This permits
series or parallel connections on either primary or secondary. Therefore, a nominal 110 V to 110 V, 220 V to 220 V, 110 V to 220 V, or 220 V to 110 V transformer
can be configured. The winding tap permits intermediate series ratings such as 208 V, 214 V, or 230 V. It is also possible to make auto-transformer connections by
connecting a primary group in series with a secondary group. Such nominal ratings as 440 V to 220 V or 220 V to 440 V can be configured in addition to the standard
ratings described above. A further advantage to auto-transformer connection is the fact that the kVA rating of a particular type is doubled.

TRK TransPort™ connectors provide touch safe electrical
terminations for power transformers, inductors, and reactors with
EI-type core assemblies. The connectors may also be attached to
bulkheads and chassis where touch safe terminations are required.
The connectors’ modular design provides superior strength and
rigidity over singular terminal components while minimizing handling
and storage issues. This series offers multiple connection schemes in
one compact package including 3/16” and 1/4” Fast-On* as well as
screw/binding clamp for hard wiring. Integral mounting holes provide
secure attachment with no need for additional insulating hardware.
General Specifications
Provides touch safe terminations and conforms to IEC60529 /
IP20 requirements
Designed to support multiple connection schemes
For use on power transformers, inductors, and reactors with EI
core assemblies
