SASO about Switching Power SuppliesSASO is the abbreviation of the English Saudi Arabian Standards Organization. Many of the SASO standards are established on the basis of the safety standards of the relevant International Electrotechnical Commission (IEC) and other international organizations. Like many other countries, Saudi Arabia has added some unique items to the standard according to its own country's civil and industrial voltage, geography and climate environment, ethnic and religious habits.The Saudi Arabian Ministry of Industry and Commerce and SASO require all products included in SASO identification standards to have SASO identification certificates when entering Saudi customs. Products without SASO certificates will be rejected by Saudi port customs. SASO authorizes the designated issuing authority to issue CoC certificates.Before custom clearance, the exporters have another three alternatives:1. Pre-shipment Compliance Verification (Pre-shipment Compliance Verification)This method is most suitable for exporters or manufacturers with very few shipments. Before each shipment, you need to apply for pre-shipment inspection and pre-shipment test. CoC certificate can be obtained if both are qualified.2. Product Registration (Registration)This method is suitable for most customers. Its advantage is that every shipment inspection is necessary, but each batch of shipment does not need to be tested before shipment. Customers can obtain the Statement for Registration (SfR) by submitting a declaration of compliance, providing a test report that meets the importing country and relevant international or domestic standards, and stating that the product has met the basic requirements of the importing country and national differences.3. Type Approval LicensingThis method can not only save the inspection fee or test fee before each shipment, simplify the repeated application procedure, but also guarantee the delivery time. Therefore, some of the shipments are more frequent or larger, and the quality and reputation are more important. Favored by the company. The exporter or manufacturer's products can only obtain the Statement for Licence (SfL) certificate if they fully comply with the mandatory standards of the importing and exporting country. The certificate is valid for one year, and the renewal of the factory inspection report and annual fee must be submitted before expiration, and it can be renewed after being reviewed by RLC. The products that have obtained the SfL certificate no longer require pre-shipment inspection (PSI) for each batch of goods, but are reduced to a few random inspections a year (usually 2-3 times/year, depending on the product status).From November 1, 2019 (the original official announcement of the mandatory date is May 1, 2019), it is mandatory to implement information products and audio-visual products into the low-voltage equipment regulations. Products exported to the United Arab Emirates must obtain a certificate before they can be sold locally.On December 1, 2020, the implementation of UAE.S IEC 62368-1 and replace UAE.S IEC 60065. UAE.S IEC 60950-1 two standards.Astek switching power supplies meet SASO.

Leakage current on Switching Power Supplies

In order to make people power on power supply units safely, one of the critical factors is leakage currents. When the current overflows through the insulation resistance, it is called Leakage current. When the leakage current is contacted by the human body, the current flows through the human body and then flows to Earth, causing electrical damage. The difference between the leakage current test and the withstand voltage test and the ground protection test is that the device is tested under operating conditions. A human body analog impedance circuit is added to the leakage current test to simulate the leakage current through the human body under real conditions.

The leakage current standard categorized into Class I, Class II and Class III by the types of Insulation, which derived from the IEC system. Now, we list as below:

* CLASS I means that the product's protection against electric shock not only depends on basic insulation, but also includes grounding. Its leakage current limits Max.0.75 mA for the handheld and 3.5mA for the other equipment.

* CLASS II means that the product's protection against electric shock not only relies on basic insulation, but also includes additional safety measures such as double insulation or reinforced insulation, but without grounding or protection depending on the installation conditions. The Max. leakage current is 0.25 mA.

* CLASS III means that the product's protection against electric shock depends on the power supply voltage as the safety extra low voltage (SELV), and no dangerous voltage is generated therein.

Astek Power Supplies pass the tests of leakage current and relative green power regulations because we care about the safety and environments. Any inquiries, please touch us asap.
