Triad Magnetics' VPM Series’ single-transformer solution leads to fewer parts and higher efficiency than using the typical space-and-time-consuming solution of using a standard 1:1 isolation transformer placed in front of a non-medically rated design.

The UL approved VPM series are rated from 25VA to 10KVA, 50/60Hz. Their shielded toroidal construction with flux band reduces stray fields while minimizing size and increasing efficiency compared to EI transformers. Additionally, they are offered with resettable over-temperature protection. 3D models are available for all VPM transformers, enabling users to check each unit’s fit in drawings, thereby saving time and money.

VPM Series 25VA-2.5KVA VPM transformers come with input taps for 100V, 120V, 220V and 240Vac. Models are offered with voltage outputs of 6, 9, 12, 15, 18, 24, 30, 36, 48, 120 or 240Vac. The many voltage choices are available for these smaller-sized transformers because these transformers are more likely be put into a piece of equipment to allow the user to eliminate an additional isolation transformer.

The larger 3000 to 10000VA VPM transformers can be used to power several pieces of equipment that require an input of 120 or 240VAC (the output of the larger VPM transformers). The input to these transformers are 208VAC or 240VAC.

“Our new VPM Series transformers offer the unique combination of low isolation and voltage step-down that can simplify medical designs while making them more efficient,” said Triad’s CEO, Bill Dull. “And although these high-performance power transformers have medical UL approval, their additional shielding, flux band, primary fusing and 155C (Class F) temperature rating also make them suitable for audio, test equipment, industrial and other applications that require high efficiency and reliability.”
