In 2015, the company announced it would supply batteries for a Hawaii microgrid to serve as backup for a 176-kilowatt solar panel array that would store 1,000 kilowatt-hours of electricity. [11] In April 2015 they announced they have been cradle-to-cradle design certified. [12] [13] It was also reported they were reducing headcount. [14]
P 3 E's power electronics research is focused on the usage of very large power insulated-gate bipolar transistors (IGBT) for intermittent and steady state operation, the use of ultra high power silicon-controlled rectifiers (SCR) for pulsed power applications, research into advanced electrical and thermal packaging, robust controls to supply ...
Seventeam Electronics (Chinese: 七盟電子) is a Taiwanese manufacturer of power supplies for Personal Computer and Industrial PC. Some earlier models from Seventeam were sold by Cooler Master [ 1 ] and SilverStone [ 2 ] under their own respective brand names.
For a given power supply, efficiency varies depending on how much power is being delivered. Supplies are typically most efficient at between half and three-quarters load, much less efficient at low load, and somewhat less efficient at maximum load. Older ATX power supplies were typically 60% to 75% efficient. To qualify for 80 Plus, a power ...
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 ...
The European Union defined a Common external power supply for "hand-held data-enabled mobile phones" (smartphones) sold from 2010, intended to replace the many incompatible proprietary power supplies and eliminate waste by reducing the total number of supplies manufactured. Conformant supplies deliver 5 VDC via a micro-USB connector, with ...
With suitable power supplies, good battery lifespan is usually achieved at charging rates not exceeding half of the capacity of the battery per hour ("0.5C"), [96] thereby taking two or more hours for a full charge, but faster charging is available even for large capacity batteries. [97]
Entry-Level Power Supply Specification (EPS) is a power supply unit meant for high-power-consumption computers and entry-level servers. Developed by the Server System Infrastructure (SSI) forum, a group of companies including Intel, Dell, Hewlett-Packard and others, that works on server standards, the EPS form factor is a derivative of the ATX ...
