AMETEK Solidstate Controls offers the ISL Series Regulating Transformer, a single-phase isolimiter designed for nuclear environments. These ferroresonant power conditioners are housed in single-system enclosures and built to deliver stable, filtered AC output even under widely varying input conditions.

The ISL Series is ideal for facilities requiring consistent power performance. It supports both standalone operation and integration into larger uninterruptible power supply systems, helping protect sensitive equipment from voltage fluctuations and electrical noise.

Built for Reliability and Harsh Conditions
Each unit is constructed with passive magnetic components and designed to operate in extreme environments. The ISL Series offers short-circuit protection that prevents secondary-side faults from affecting the primary input, ensuring uninterrupted operation.

Key features include:

  • High reliability and efficiency
  • Attenuation of common and transverse mode noise
  • Low audible noise under 65 dBA
  • ¼ cycle output ride-through
