Unmatched Transformer Performance for Demanding Applications
Optimized for High Efficiency and Reliability:
Our transformers are optimized for high efficiency across a wide range of frequencies (0-10kHz+), providing reliable performance in power systems with varying demands. This capability ensures minimal energy loss, maintaining system efficiency and reducing operational costs. The integration of liquid-cooled technology further enhances thermal performance, allowing our transformers to operate at peak performance while minimizing heat in the surrounding environment, a critical factor for systems in tight spaces or those with high thermal loads.
Compact Design with High Power Density:
Our toroidal transformers feature a compact, space-saving design that maximizes power density while minimizing their physical footprint. This unique design allows for higher power output in a smaller, more efficient package compared to traditional EI-core transformers. The result is less weight, reduced material usage, and lower overall system costs, all without compromising on performance.
Liquid Cooling:
Our patented liquid cooled technology enables higher thermal efficiency, power density, and performance. With liquid cooling, 97% of the transformer heat is captured by the coolant with only 3% released to ambient. This reduces the need for additional cooling and allows for more flexibility in locating transformer near temperature sensitive equipment.
