LR30AC-EU-M01 EMC Testing: What B2B Buyers Should Check Before Charger Shipment
Learn what importers should check before LR30AC-EU-M01 charger shipment, including CE EMC results, ESD, surge immunity, output rating, labeling, and packaging.
LR30AC-EU-M01 EMC Testing: A practical inspection guide based on LR30AC-EU-M01 CE test results
Before a USB-C wall charger is shipped, B2B buyers should check more than appearance. Output performance, EMC behavior, label accuracy, packaging, and document matching all affect the final selling result.
The LR30AC-EU-M01 CE EMC report provides a useful example of what importers, wholesalers, distributors, and private label brands can review before confirming a charger order.
Tested Product Overview
The CE EMC report lists the tested product as Quick Wall Charger.
Model information:
- Tested model: LR30AC-EU-M01
- Related model: LR30AC-UK-M01
- Input: AC 100–240V, 50/60Hz, 1A Max
- USB-C output: 5V/3A, 9V/3A, 12V/2.5A, 15V/2A, 20V/1.5A
- USB-A output: 5V/3A, 9V/2A, 12V/1.5A
- USB-A + USB-C output: 5V/3A
These details should match the quotation, approved sample, product label, and final packaging.
EMC Test Summary
The LR30AC-EU-M01 report shows Pass results for several EMC-related test items, including:
- Disturbance voltage at mains terminals
- Radiated disturbance from 30MHz to 6GHz
- Voltage changes, voltage fluctuations and flicker
- Electrostatic discharge immunity
- Radiated RF electromagnetic field immunity
- Electrical fast transient/burst immunity
- Surge immunity
- Conducted RF immunity
- Voltage dips and interruptions immunity
Why This Matters
For USB-C chargers, EMC performance is important because the product connects directly to AC power and works near phones, tablets, laptops, and other electronic devices.
For B2B buyers, CE EMC documentation helps support:
- Retail product review
- Distributor document requests
- Private label project files
- Customer compliance checks
- Pre-shipment confirmation
ESD Immunity Test
The LR30AC-EU-M01 EMC report includes electrostatic discharge testing.
Test levels include:
- Contact discharge: ±4kV
- Air discharge: ±8kV
- Minimum 10 discharges per location
- Test result: Pass
This is important because wall chargers are touched frequently during daily use.
EFT and Surge Immunity
The report also includes:
- EFT/B test on AC power port: ±1kV
- Surge immunity on AC power port L-N: 1kV positive and negative polarity
- Test result: Pass
These test items help buyers understand how the charger was reviewed under electrical disturbance conditions.
What Buyers Should Check Before Shipment
Before shipping LR30AC-EU-M01 bulk orders, buyers should confirm:
- Model number: LR30AC-EU-M01
- Plug type: EU version or UK version
- Output rating on label
- USB-C and USB-A function
- CE EMC document
- CE LVD document
- ErP and RoHS document support
- Product appearance
- Packaging artwork
- Barcode and carton marks
- Quantity and packing method
