Ultra-Isolation Transformers

Noise-less Power Supply Units of Servomax Limited

Ultra-isolation transformers are one kind of isolation transformers. In addition to the galvanic isolation and safety, they are specialized in suppressing the disturbing effects of power interruptions. They reduce the problems that arise with spikes, surges, transients, spikes, etc. Noise and other power variations caused by these common issues are perfectly avoided by Servocare’s ultra-isolation transformers. They are designed with special advanced technologies and engineering strategies to enable reliable performance. Our manufacturing and testing methods are maintained as per national and international standards – we build customized models of ultra-isolation transformers with capacities up to 3000 KVA.


Ultra-isolation transformers are necessary and helpful for various applications.

  • Computers and Peripheral Systems
  • CNC Machines
  • Digital Communication Telemetry Systems
  • Industrial Machinery and Equipment
  • Medical Instrumentation


Our ultra-isolation transformers are highly beneficial.

  • They use high-insulation materials and special shielding techniques to reduce the noises.
  • They also have specialized core designs to block higher frequencies.
  • They protect the best-levels of protection against impulse noise, bus short-circuit, accidental discharge of capacitors, strong lightning, etc.
  • They save the microprocessor-based equipment and instruments from damages.
  • They are available in different sizes and capacities fitting the customized demands.
