CTIA certification is a battery certification project in the United States. CTIA's full name is the Cellular Telecommunications Industry Association (also known as The Wireless Association), and Chinese people call it the "American Wireless Communications and Internet Association". Due to the fact that these wireless communication products all use batteries without exception, CTIA also has strict certification requirements for batteries. Nowadays, CTIA battery certification has become a mandatory entry requirement for North American telecommunications operators. The standards are based on IEEE 1625 (Standard for Rechargeable Batteries for Portable Computers) and IEEE 1725 (Standard for Rechargeable Batteries for Mobile Phones), which test, approve, and certify battery cells, battery packs, adapters, and entire systems. In addition, the certification also requires factory audits of battery cell manufacturers, specifically focusing on key processes and their quality control, quality system, and technical capabilities in the battery cell production process.
CTIA Battery Certification Process
1. The applicant signs a contract with the laboratory.
2. The applicant applies for an account online through the CTIA database.
3. The applicant submits an authentication application to CTIA through the CTIA database.
4. The applicant selects the laboratory as CATL to evaluate IEEE1725 conformity online.
5. The applicant submits a conformity declaration.
6. The applicant receives an Invoice from CTIA and pays to CTIA.
7. The applicant submits the required samples and documents to the laboratory.
8. The laboratory evaluates and ultimately uploads the evaluation report to CTIA.
9. After the evaluation report is uploaded, CTIA signs a contract with the applicant.
10. CTIA acknowledges the sub-system or system when all the steps are completed.
11. After recognition, the sub-system or system information can be viewed online.
Power Supply, UPS, Transformer
Power Supply, commonly known as UV power adapter, can be divided into boost or buck based on the output voltage; If distinguished by design technology, it can be further divided into traditional Linear Adapter/Power Supply or Switching Adapter/Power Supply; If distinguished by the final application location, it can also be classified as standalone or embedded; Finally, distinguished by the input/output current, it can be divided into:
AC to AC、
AC to DC、
DC to AC、
There are four categories: DC to DC.
Commonly Used uv Uninterruptible Power Supplies in the Market, Divided into the Following Types According to Their Application Scope:
Information/Communication: Applied to audio and video in information or communication products. Such as LCD Monitor, Scanner, Printer, FaxMachine, modem digital camera, etc;
Audio and Video Products: Used for power supply in audio and video products such as CD Player, DVD Player, cassette player, game console, and LCD TV;
General Use: If the power supply is not specified for a specific product and is for general use, it is mostly used in household appliances;
Charger: Refers to chargers for general rechargeable batteries, such as professional chargers for mobile phones or digital cameras. Spray gun manufacturers may consider classifying this type as information products;
Power Inverter: Refers to products with low voltage input (such as connecting a car battery 12VDC) and high voltage output of 120VAC or 230CAC.
Uninterrupted UV intelligent variable frequency power supply: Rectify the mains power into DC power, and then invert it into AC power output; Simultaneously charge the battery. When the mains power is interrupted, it automatically converts the DC output of the battery into AC output to the device. The abbreviation in English is UPS.
Product Certification Relevant International Regulatory Requirements
The power supply reduces or increases the voltage of the mains power supply to the mains voltage, so there are two versions: 100-120VAC and 200-240VAC. Small UV electronic power supplies are mostly designed as direct wall plugs. If the product is planned to be marketed globally, various plug types are also considered.
Power supply regulations usually require compliance with safety and electromagnetic compatibility (EMC) requirements, with safety standards being more complex. Electromagnetic compatibility only poses significant challenges when switching power supplies, while linear power supplies rarely encounter EMC issues.
When a power supply supplies power to different products, the regulatory standards that it should comply with are also different. In principle, the regulatory standards that it needs to comply with are determined by which product it needs to be used with.
