ZPI30S Switching Power Supply From ZETTLER Offers Efficiency and Reliability

Posted on by

ZETTLER USA introduces the new ZPI30S switching power supply – a compact, robust solution for demanding industrial applications. With an output of 30W, a wide input voltage range and comprehensive protection functions, it guarantees a reliable power supply, even under extreme conditions.

Innovative features for a wide range of applications

ZETTLER’s ZPI30SXX00WN-0SF model offers numerous advanced features, including a high energy efficiency of 85%, a wide input voltage range from 90VAC to 305VAC, as well as protection functions against overvoltage, overcurrent and short circuits. With its compact design, the module is particularly suitable for applications in industry and in e-charging systems. It also meets international standards such as EN62368-1 and EN55032 Class B for electrical safety and electromagnetic compatibility.

Robust and versatile

Thanks to the wide operating temperature range of -30°C to +70°C and a high isolation voltage of 3000VAC, the ZPI30SXX00WN-0SF offers exceptional reliability in harsh environments. The integrated EMI filter and low standby power consumption (<0.1W) make the module particularly environmentally friendly and meets the highest efficiency requirements.

Zettler Magnetics develops a high-frequency transformer for e-mobility market

The expansion of the electromobility market has provided consumers with choice in EV cars ranging in battery size and range.  Vehicles with larger battery sizes like the Tesla Model S provide users with over 300 miles of range, meaning a single charge can last an entire week for most users.  Other vehicles like the Nissan Leaf or Hyundai Ioniq provide less than half the range and charge times meaning some users could expect more frequent charges. When limited to 7kW single phase charging systems, the longer charge times force users to carefully manage their charging and travel times.The availability of 3 phase EV supply equipment (EVSE) simplifies the user experience by providing faster charge times ranging from roughly half the charge time for a 11kW EVSE to a third of the charge time for a 22kW EVSE.

high-frequency transformerA leading manufacturer in charging infrastructure approached ZETTLER Magnetics in need of a high-frequency transformer for its internal switch mode power supply (SMPS). The challenge for the engineers at ZETTLER was to develop a high-efficiency switching transformer for high input voltages up to 400VAC in a new 3-phase EV charging cable. ZETTLER Magnetics met these challenges with a custom designed high frequency switching transformer, providing for the smallest possible space while also complying with common UL and IEC61558 standards.

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.
