A label on one side of the box lists technical information about the power supply, including safety certifications and maximum output power. Common certification marks for safety are the UL mark, GS mark, TÜV, NEMKO, SEMKO, DEMKO, FIMKO, CCC, CSA, VDE, GOST R mark and BSMI. Common certificate marks for EMI/RFI are the CE mark, FCC and C-tick ...
A power supply is an electrical device that supplies electric power to an electrical load. The main purpose of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load. As a result, power supplies are sometimes referred to as electric power converters. Some power supplies are ...
In contrast, a linear power supply regulates the output voltage by continually dissipating power in the pass transistor. The switched-mode power supply's higher electrical efficiency is an important advantage. Switched-mode power supplies can also be substantially smaller and lighter than a linear supply because the transformer can be much smaller.
When a company resells an OEM power supply under a new name, it must be certified under the new name and company, even if the OEM supply is certified. In some instances, a reseller has claimed a higher wattage than the supply can deliver, so the reseller's supply would not meet 80 Plus requirements.
Direct current (DC) (red line). The vertical axis shows current or voltage and the horizontal 't' axis measures time and shows the zero value. Direct current (DC) is one-directional flow of electric charge. An electrochemical cell is a prime example of DC power.
A regulated power supply is an embedded circuit; it converts unregulated AC (alternating current) into a constant DC. With the help of a rectifier it converts AC supply into DC. Its function is to supply a stable voltage (or less often current), to a circuit or device that must be operated within certain power supply limits.
The NATO Stock Number or National Stock Number (NSN) is a 13-digit alphanumeric code consisting of a Group of Supply, a Class of Supply and the unique NIIN to designate unique items of supply grouped by their relative catalog category. The first four digits are the NATO Supply Classification (NSC) or Federal Supply Class (FSC) code.
Basing on the decision made, the applicant receives the Certificate of Conformity to Fire Safety or not. The list of the documents necessary for drawing up the Fire Safety Certificate: OGRN; The requisites; The application; The statistics code; INT (Identification Number of a Taxpayer); The document of property or the contract of lending the ...
