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)

Technical Support

Signal’s staff of application engineers is one of the largest in the industry. Their extensive knowledge of regulatory and safety

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

• VDE certified to EN 60998-2-1 (VDE 0613), rated at 450V, 41A,

Reg-Nr B503

• CSA certifed to CAN/CSA C22.2 (# 0-M91, 158-1987),

Certificate # 1803371

• Certifed to UL 1059, UL 310 and UL 486E

• RoHS compliant

* The 1/4” Fast-On spade lug P/N 250-FO-SL can also be purchased

separately.
