  2. EIAJ connector - Wikipedia

    en.wikipedia.org/wiki/EIAJ_connector

    This is a unique-looking barrel connector, apparently intended for providing a DC output jack (most DC jacks are used for power input).. Possibly available in multiple voltage ranges, the one for voltage classification 2 (3.15 to 6.3 V) has an outside diameter of 4.75 mm and a protruding pin of 2.5 mm diameter.

  3. Voltage converter - Wikipedia

    en.wikipedia.org/wiki/Voltage_converter

    A simple voltage dropper can be used to reduce the voltage for low-power devices; if more than 12V is required, or for high-powered devices, a switched-mode power supply is used. The output will usually be DC in the range 1.5–24 V. Power supplies that output either 100–120 V AC or 210–240 V AC are available; they are called inverters ...

  4. Switched-mode power supply - Wikipedia

    en.wikipedia.org/wiki/Switched-mode_power_supply

    Stand-alone switched-mode power supply An adjustable switched-mode power supply for laboratory use. A switched-mode power supply (SMPS), also called switching-mode power supply, switch-mode power supply, switched power supply, or simply switcher, is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently.

  5. Jaycar - Wikipedia

    en.wikipedia.org/wiki/Jaycar

    Jaycar was founded when Gary Johnston, a former Dick Smith Electronics employee, purchased John Carr & Co. Pty Ltd. He became managing director of the company. [4]In 2005, Jaycar received negative attention from its imported Taiwanese "Choke-A-Chicken" toy that squawked and flapped its wings when strangled around its neck, [5] [6] described by the RSPCA Queensland as "grossly irresponsible".

  6. AC adapter - Wikipedia

    en.wikipedia.org/wiki/AC_adapter

    In 2006 Larry Page, a founder of Google, proposed a 12 V and up to 15 A standard for almost all equipment requiring an external converter, with new buildings fitted with 12 VDC wiring, making external AC-to-DC adapter circuitry unnecessary. [17] [18]

  7. Rectifier - Wikipedia

    en.wikipedia.org/wiki/Rectifier

    The primary application of rectifiers is to derive DC power from an AC supply (AC to DC converter). Rectifiers are used inside the power supplies of virtually all electronic equipment. AC/DC power supplies may be broadly divided into linear power supplies and switched-mode power supplies. In such power supplies, the rectifier will be in series ...

  8. 16-pin 12VHPWR connector - Wikipedia

    en.wikipedia.org/wiki/16-Pin_12vHPWR_connector

    Despite these claims of user error, a revised connector design intended to address these issues was introduced under the new name 12V-2x6. [21] In February 2024 the U.S. Consumer Product Safety Commission announced a voluntary recall of 12VHPWR adapters made by Cablemod. According to the recall filing, 272 reports were filed with about 25300 ...

  9. DC-to-DC converter - Wikipedia

    en.wikipedia.org/wiki/DC-to-DC_converter

    A DC-to-DC converter is an electronic circuit or electromechanical device that converts a source of direct current (DC) from one voltage level to another. It is a type of electric power converter . Power levels range from very low (small batteries) to very high (high-voltage power transmission).
