Introduction
1. Standard Overview and Scope of Application
GB/T 37139—2018 specifies the electromagnetic compatibility (EMC) requirements for DC power supply equipment, which is applicable to equipment with a DC power port and a rated voltage not exceeding 1500V DC. The standard covers equipment classification, measurement conditions, product documentation, applicability, and emission and immunity requirements.
2. Comparative analysis of standard frameworks
| Standard dimensions | Class A equipment requirements | Class B equipment requirements |
|---|---|---|
| Equipment classification | Applicable to industrial environments | Applicable to residential environments |
| Measurement conditions | Measurement under typical usage conditions | Representative equipment configuration |
| Immunity requirements | Higher electromagnetic protection standards | Simplified test process |
3. Implementation suggestions and case analysis
Implementation suggestions:
- During the equipment design phase, clarify the EMC requirements of the DC power port and conduct pre-tests.
- Choose the appropriate classification standard (Class A or Class B) according to the equipment use environment.
- During the measurement process, ensure that the auxiliary equipment and configuration meet the manufacturer's specifications.
- For complex systems, it is recommended to use shielded cables to reduce electromagnetic interference.
