Encapsulated Power Transformers from ZETTLER: Smaller, Cooler, Cheaper

Engineers working on applications in LED Lighting, Electric Metering, Motor controls and Thermo Controls keep asking for transformer solutions with smaller footprints, less heat emission at lower prices, and, of course, a Class 2 UL rating.

ZETTLER, a company with years of development experience in the design of encapsulated linear power transformers is responding to these requests with its top-of-class BV series of sealed transformers.

• Deliver significant reduction in physical footprint compared to traditional open frame formats.
• Have superior thermal characteristics that make them run up to 5°C cooler in continuous duty, and up to 40°C cooler in surge testing than previous generations, due to ultra-high winding efficiency and vacuum-sealed epoxy processes.
• Feature an unrivaled 14kV surge withstand capability based on a patent pending Zettler split-bobbin design.
• Provide minimized EMI noise without the added cost of a shield, as a result of proprietary assembly methods employed at Zettler Group’s China wholly owned manufacturing facilities.

With output loads ranging from 0.6-10VA, ZETTLERs BV series is perfect for a wide range of products including thermostats, lighting controls, and oxygen concentrators. Dielectric strength is 4200Vrms, and external insulation is optional for increased dielectric withstand between the component and the PCB. ZETTLER BV transformers are also ideally suited for the alternative energy market - Solar inverters and smart grid meters are just two possible applications.

ZETTLERs highly automated production lines makes the BV series price competitive when compared to similarlysized open frame models. Samples are available on request.
