Power products

Power supplies, generally called power adapters, can be divided into step-up or step-down if they are distinguished by the output voltage; if distinguished by design technology, they can be divided into traditional linear power supplies or switching power supplies ; If distinguished by the final application position, it can also be divided into stand-alone type or embedded; finally distinguished by the input/output current, it can be divided into AC to AC, AC to DC, DC to AC, DC to DC Four categories.

        The power supply reduces the mains power supply or raises the low voltage to the mains voltage, so there are two versions of 100-120VAC and 200-240VAC. Most of the small power supplies are designed to be directly plugged into the wall. If the product is planned to be sold globally, Many plug types are also considered.

        The power supply regulations usually meet the requirements of safety (Safety) and electromagnetic compatibility (EMC). The safety specifications are more complicated. The electromagnetic compatibility is only a problem when switching power supplies. The traditional linear power supply The electromagnetic compatibility problem rarely occurs with the device.

        When the power supply supplies power to different products, the regulations and standards that it should comply with are also different. In principle, the regulations and standards that it needs to comply with are determined by which products it should be used with.

        Product Range:

         Information/communication (such as LCD Monitor, Scanner, Printer, FaxMachine, Modem Digital Camera, etc.), audio-visual products (such as CD Player, DVD Player, radio and tape recorder, game console, and LCD TV, etc.), general purpose (if not specified For what kind of product, it is a general-purpose power supply, most of which are used in home appliances), chargers (referring to general rechargeable battery chargers, such as professional chargers for mobile phones or digital cameras, manufacturers will consider using information Products are classified into this type), inverters (refer to products with low-voltage input (such as 12VDC connected to car batteries) and high-voltage 120VAC or 230CAC output), uninterruptible power supplies (rectify the mains power to direct current, Then invert it to AC output; charge the battery at the same time. When the city power is interrupted, it automatically converts the battery output DC to AC output to the equipment, the English abbreviation is UPS).

        Executive standard:
