The customer was unable to meet the strict requirements of EN IEC 61326-1:2021 with its compact 1.5 kW and 3 kW laboratory power supplies (1U height), and TPS became a key partner for successful certification.
▎ From failure to certification: Efficient remediation within one week
The first EMC test run showed that the requirements of EN IEC 61326-1:2021 were not met. TPS immediately responded with a targeted optimization strategy:
✓ Precise interference source localization using near-field probes
✓ Optimization of the PCB layout and shielding structure
✓ Targeted redesign of the filter circuits
The result: Successful completion of all EMC tests at the TÜV Shanghai laboratory while simultaneously meeting the CE directive requirements – with over 50% less certification effort and remediation costs for our customer.
▎ More than just a test mark – certification with real added value
CE/EMC certification provides far more than just regulatory compliance:
✅ Secure market access for the EU and global lead markets
✅ Reliable EMC performance at 1.5–3 kW in 1U form factor
✅ Minimized risk in development and production
TPS stands for:
◆ Leadership in high-density designs with EMC compliance
◆ Fast EMC diagnostics for complex laboratory equipment
◆ Efficient handling of international certifications – end-to-end
