Power Supply

电源做CB

可以做如下标准

• UL/IEC 62368+60950 +IEC60065

电源做GS

申请GS，一般先做CB，做完CB再用这个CB转，比较好：

• IEC 61558-1
• IEC 61558-2-16

电源做ETL与CETL

• CAN/CSA-C22.2 No. 223-M91

• UL 1310
• CSA 223M91（CAN/CSA-C22.2 No. 223-M91 (R2013)）

Power Supplies with Extra-Low-Voltage Class 2 Outputs 1. Scope 1.1 This Standard applies to (a) power supplies including transformer units of both the direct plug-in and cord-connected types that utilize a step- down, isolating transformer of the extra-low-voltage secondary type and that may incorporate rectifiers and other components to provide an ac or dc output; and (b) battery chargers for rechargeable batteries. Note: For convenience, the term power supply may be used throughout the Standard. 1.2 This Standard applies to power supplies intended for use indoors in nonhazardous locations in accordance with the Rules of the Canadian Electrical Code, Part I, when connected to a nominal system voltage of 120 V or 240 V supply and having an output conforming to the requirements for an extra-low-voltage Class 2 circuit. 1.3 This Standard applies to power supplies intended to supply extra-low voltage for the operation of products such as household electronic equipment, telephone equipment, communications equipment, and motor-operated equipment. 1.4 This Standard does not include requirements for batteries other than that they must be suitable for recharging. 1.5 This Standard does not apply to automotive or nonautomotive battery chargers that do not have an extra-low-voltage Class 2 output, or transformerless, nonisolated battery chargers for charging special purpose battery packs, as covered by CSA Standard CAN/CSA-C22.2 No. 107.2, Battery Chargers.
