The Triad Magnetics Power Transformer, part number 28M9311, is a chassis mount transformer designed for dual primary and dual secondary applications. It has a maximum power rating of 25VA and operates at primary voltages of 230VAC at 50/60Hz or 115VAC at 50/60Hz. The secondary outputs are configurable for 24V center-tapped at 1.0A or 12.0V at 2.0A, allowing for flexibility in various circuit designs. This transformer features a voltage regulation of 25% typical from full load to no load and a temperature rise of 30¬8C, with a maximum allowable rise of 45¬8C. It provides 4000VAC isolation between the primary and secondary windings, ensuring safety in operation. The construction includes a dual bobbin design with an insulated shroud made from high-temperature materials that exceed UL flammability standards. The transformer is compliant with RoHS regulations and has been certified by UL, CSA, and TUV for general-purpose applications. Recommended fuses for the transformer are specified for both series and parallel configurations, ensuring proper protection during operation. The dimensions and mounting specifications are suitable for various applications, making it a versatile choice for engineers.
Triad chassis mount World Series transformers are designed to meet U.S. and International standards including CSA, IEC, TUV and UL requirements. The transformers consist of a dual bobbin design positioned inside an insulating shroud and constructed with UL approved high temperature material. This design eliminates the need for electrostatic shielding since there is minimal capacitance between coils when using a dual bobbin configuration. The primary and secondary are both electrically isolated more from each other, and from the core itself. Chassis mount World Series transformers are available in sizes ranging from 25 VA to 175 VA, and are equipped with convenient "quick connect" terminations. less

TRIAD Magnetics chassis mount world Series transformers are designed to meet U.S. and international standards including CSA, IEC, VDE and UL Requirements. The transformers consist of a dual bobbin design positioned inside an insulating shroud, and constructed with UL Approved high temperature material. This design eliminates the need for electrostatic shielding since there is minimal capacitance between coils when using a dual bobbin configuration. The primary and secondary are both electrically isolated from each other, and from the core itself. Chassis Mount World Series transformers are available in sizes ranging from 25 VA to 175 VA, and are equipped with convenient “quick-connect” terminations. Technical Notes: 1. Hi pot tested at 4000 RMS. 2. Both primary and secondary coils may be connected as either series or parallel, but both must be used simultaneously. Specifications. Primary: 115/230 V, 50/60 Hz.
