Notes: 

Performance criteria are based on EN55024. According to the standards, performance criteria are decoded as following: 

- A. Normal performance during and after the test 

- B. Temporary degradation, self-recoverable 

- C. Temporary degradation, operator intervention required to recover the operation 

- D. Permanent damage

Notes: 

1. Recommended assembly screws - It is recommended to use M3 SEMS screws with heads that do not exceed 5.5 pie. 

2. Assemble on a metal plate with metal standoffs getting better EMI performance. When installing the power supply into the end-product, a non-conductive insulator should be placed between the unit and any conductive metal chassis or mounting platform. 

3. All dimensions in mm. 

4. This power supply requires mounting on metal standoffs 0.20" (5 mm) min. in height. 

5. Weight: 370 g.
