[2] [3] [4] A laboratory ("lab") power supply normally implies an accurate bench power supply, while a balanced or tracking power supply refers to twin supplies for use when a circuit requires both positive and negative supply rails).
The 16-pin 12VHPWR connector is a standard for connecting graphics processing units (GPUs) to computer power supplies for up to 600 W power delivery. It was introduced in 2022 to supersede the previous 6- and 8-pin power connectors for GPUs. The primary aim was to cater to the increasing power requirements of high-performance GPUs.
The addition is a 3 ⁄ 16-inch (4.8 mm) diameter round or U-shaped ground pin, 1 ⁄ 8 in (3.2 mm) longer than the power blades (so the device is grounded before the power is connected) and located from them by 1 ⁄ 4 in (6.4 mm) edge-to-edge or 15 ⁄ 32 in (11.9 mm) center-to-center.
An external power supply, AC adapter or power brick, is a power supply located in the load's AC power cord that plugs into a wall outlet; a wall wart is an external supply integrated with the outlet plug itself. These are popular in consumer electronics because of their safety; the hazardous 120 or 240 volt main current is transformed down to a ...
Another way to avoid the transformer inrush current is a "transformer switching relay". This does not need time for cool down. It can also deal with power-line half-wave voltage dips and is short-circuit-proof. This technique is important for IEC 61000-4-11 tests. Another option, particularly for high-voltage circuits, is to use a pre-charge ...
