When designing electrical equipment for international markets, engineers are forced to consider the requirements of a seemingly growing number of countries. If equipment is connected to the electrical grid, this includes additional safety requirements to isolate and protect people and property from dangerous voltage levels.

For designers in need of linear Class 2 transformers, Zettler offers a robust line of international power transformers with an industry leading 4200Vrms isolation rating.  A leading US appliance manufacturer recently chose Zettler Magnetics’ AHI01024 transformer for one of their products supplied globally. The appliance was designed for a commercial kitchen environment, meeting the high standards and daily routine of a busy restaurant.

The Zettler AHI series of laminated PCB transformers offer 115V or 230V input capability in 2.5VA, 5VA and 10VA configurations with outputs ranging from 5VAC to 36VAC.  They are UL Class 2 recognized, constructed with a UL Class B (130°C) insulation system, and conform to IEC/EN61558-1.  Custom options are also available.

Please contact us with any of your transformers needs and/or visit the Zettler Magnetics website for further details.

High Frequency Ferrite Transformers are a major component of switching power supplies, and choosing the right product configuration is a key element in any power supply design.

ZETTLER Magnetics’ proven formula of close customer engagements focused on individual design requirements, combined with highly cost-effective manufacturing automation is perfectly suited for many industry applications.

Application example: Household Appliances

Recently, an industry-leading home appliance manufacturer asked Zettler Magnetics to design a 2.6W switching power supply transformer with a wide input voltage range that meets several critical requirements including: electromagnetic interference performance to achieve EN55022, pass 85/85 temperature and humidity testing to meet IEC61558, and meet IEC60335 electrical performance and structural insulation requirements.

A team of Zettler Magnetics engineers custom-designed a transformer by performing double-layer shielding of the inner and outer layers, while using minimalist skeleton design.

The tailor-made transformer met the customer required design parameters, simplified materials during the design process, while also optimizing the electrical performance of the product, and enabling fully automated high-volume production.

 
Zettler Magnetics produces more than 40 million transformers per year and has power supplies ranging from more than 50 different form factors to 1W to 1KW. To support a wide range of applications from washing machines and kitchen appliances to lighting and the Internet of Things.

Product Spotlight October 2018

Over recent years, Zettler Magnetics has expanded its range of High Frequency Ferrite Switching Transformers to now cover more than 50 different form factors, supporting power supply designs ranging from 1W to 1KW.

Selection of the appropriate structure is a critical element in any power supply design, which needs to consider a variety of electrical, safety and mechanical parameters.

Appropriate solutions therefore typically involve custom designs. At the same time, customers expect competitively priced solutions.

Zettler Magnetics response to this challenge is based on a two-pronged approach. An experienced team of transformer design-engineers closely engages with the customer in regard to individual design requirements, while highly automated production lines support a broad range of possible form factors, hence allowing us to manufacture high-volume custom designs at very competitive prices.

Example Application: Outdoor Lighting Control

Recently, an industry leader in Street Lighting Control requested Zettler Magnetics to design a 2.6 Watt wide input-range, custom switching transformer. The customer had unique requirements for operating temperature, UL Class B insulation, and physical size constraints within the Controller. Zettler was able to design a custom transformer meeting all of these design parameters. The bespoke design was tailored to suit Zettler’s high volume automated production line capabilities, resulting in a highly cost-effective solution for this transformer application.

Zettler Magnetics manufactures more than 40 million Switching Transformers each year to support a diverse range of applications from washing machines and kitchen appliances to Lighting and IoT. Many of these high-volume designs are manufactured on fully automated production lines in Zettler’s wholly owned manufacturing facility in Xiamen, China.

Application Spotlight February 2018

The Design
Application solutions for residential security systems require highly reliable,
low-frequency power transformers with UL recognition. At the same time, the price
competitive nature of the residential security business also dictates the need for
low cost solutions. A leading manufacturer of home security systems recently put
these requirements to the ZETTLER Magnetics engineering team. In addition, the customer
also demanded a transformer in a compact size and with excellent heat dissipation
to accommodate the sleek and modern design of the control panel of the application.
ZETTLER’S 1.5VA BV series encapsulated transformer seamlessly met all these requirements while costing less than an electrically equivalent
laminated transformer.

About the transformer
ZETTLER’S versatile BV series of encapsulated transformers are less expensive than traditional laminated transformers while providing better
performance… the best of both worlds! Encapsulating the transformer in epoxy
improves isolation and heat dissipation, which allows for a smaller package size
that still meets UL’s stringent class II standards. Suitable for a wide range
of industrial control applications ZETTLER’s BV series [/encapsulated-power/]
is available in 115V or 230V inputs and from 0.35VA to 10VA. ZETTLER builds the
BV series, at our factory
in Southern China, on automated production lines which ensure consistent quality
at a very competitive price.
