Buying advice

When choosing an isolation transformer, prioritize your equipment's power requirements and the level of noise filtering needed. For sensitive audio or medical devices, models like the Tripp Lite IS series or Furman conditioners offer excellent isolation. Consider the number of outlets and form factor for your space. Be aware that true isolation transformers with separate winding are bulkier and heavier than surge protectors.
