Why Your Current Transformers May Be Costing You More

  • High Purchase Price: Conventional EI transformers sourced from low‑margin suppliers often exceed budget by 15‑25%.
  • Inconsistent Quality: 30% of field failures are traced to sub‑standard winding insulation and non‑uniform magnetic cores.
  • Long Lead Times: Overseas shipments average 45‑60 days, delaying production schedules.
  • Regulatory Gaps: Missing CE, RoHS, or FCC certifications can halt product launches in the U.S. market.
  • Limited Customization: Off‑the‑shelf designs rarely meet specific voltage‑ratio or footprint requirements for medical or industrial equipment.
