Choosing Your Ideal Partner

Three practical tips when selecting manufacturers:

  1. Verify UL 1741 and IEC 62989 certifications
  2. Request third-party test reports
  3. Compare actual field performance data

Remember: The cheapest option often becomes the most expensive in the long run. Balance initial costs with lifetime value.

Pro Tip

Ask manufacturers for thermal imaging reports – proper heat dissipation design separates quality products from mediocre ones.
