Why Your Current Transformers Are Costing You More
- High Unit Price: Off‑the‑shelf units often carry a 30‑40% markup due to middle‑man fees.
- Inconsistent Quality: 15% of customers report premature failures or excessive hum noise.
- Long Lead Times: Standard stock can take 6‑8 weeks to ship from overseas warehouses.
- Regulatory Gaps: Non‑certified parts may violate CE, FCC, or RoHS requirements in the US market.
- Limited Customization: Size, winding ratio, and shielding options are rarely adjustable.
Result: Higher total cost of ownership, production delays, and compliance risk.
