A connector with a limited ampacity supplies a load which draws more current than the ampacity of the connector. A buck converter changes the power passing through the connector to a higher current at a lower voltage to energize the load. Alternatively, if the load is intermittent, the current passing through the connector may charge a large capacitor which is able to supply a larger current to the intermittent load. The capacitor may also be used to power a continuous load, such as a memory, du...

A supply cabinet with inventory sensors in a bore/slot arrangement. The supply cabinet contains a plurality of vertically adjustable shelves. Each shelf has a plurality of bore/slot arrangements extending from the front to the rear of the shelf. Each bore/slot arrangement secures a plurality of containers, which are suspended from a lower surface of the shelf.

The transducer supply is configured for supplying a passive transducer arranged in an explosion-hazard zone with electrical energy from a DC voltage source. The electrical energy is transmitted via a two-wire connection, via which in the opposite direction the measured value sensed by the transducer is transmitted by the transducer setting the direct current obtained from the DC voltage source to a value variable between two limit values. As a means of protection a transformer is inserted in the...

A power supply includes a housing, a printed circuit board, at least one electrical element and a fan assembly. The housing has an interior and an exterior. The printed circuit board is provided in the interior of the housing, while the electrical element is attached onto the printed circuit board. The fan assembly is also provided in the interior of the housing. The fan assembly includes a shell and a fan. The shell includes two surface boards and plural side walls connected between the two sur...

A power supply or converter has an AC-voltage source to which a number of rectifiers are connected, with at least one of the rectifiers having a switching stage by which, in a feedback mode, energy can be fed back to the AC-voltage source from a DC-voltage terminal and/or from a capacitor of the rectifier. Such an arrangement achieves an energy symmetry among a number of connected users, e.g. back-feeding output stages, with low losses and low cost in terms of circuitry.

A power supply comprising switching elements (20), wherein the power supply is provided with first heat sinks (30) having electrical conductivity to which the switching elements are fitted and a second heat sink (40) mounted with the first heat sinks which are electrically insulated, and first heat sink is used as one terminal for the switching elements, and the first heat sinks each having a projection, to be in contact with outside terminals (81), (82).

A power supply in which power conversion efficiency is enhanced in all operation modes by supplying power to a load (60) from any one or both of first power supply circuit (20) and second power supply circuit (40), detecting the operation mode of the load (60) through an operation mode detecting means (65), and controlling switches (11,12) depending on the operation mode of the load (60) to select a power supply circuit for supplying power to the load (60).

A power supply particularly suitable for high-speed optical data transmission employs readily available components to achieve desired voltage tolerances. More specifically, a voltage signal supplied to a load is converted into a digital signal and provided to a processor that derives a digital correction signal from the digital signal. The digital correction signal is then converted to an analog correction signal and is used by a feedback control circuit in the power supply to regulate the outpu...

The electric supply allows a rapid switching of PIN diodes from their on state to their blocked state while limiting the electric power supplies required, and for that is used a current amplifying loop allowing upon order to bring almost instantaneously the current to the value desired, while maintaining a low consumption at rest, and it is particularly advantageous to associate this system to a low voltage generator allowing to eliminate the minority carriers, since in this case the high voltag...

A supply tank for supplying fluid to a tandem master brake cylinder of a motor vehicle. The tank has a bottom section and a top section which is not shown. The bottom section comprises a partition wall which separates the two chambers from each other, the partition wall being formed with a passage which is arranged approximately in the center of the bottom section. In each chamber, an outlet is configured at each end of the bottom section. From each outlet and along the partition wall toward the...
