Most forms of uninterruptible power supply (UPS) can be either powered by battery or flywheel energy. These are ready for immediate use at the instant that the mains electricity fails, but the relatively small and finite amount of stored energy they contain makes them suitable for short periods of use, typically in the order of a few dozen minutes to a couple of hours depending on the actual load.
A UPS designed for powering DC equipment is very similar to an online UPS, except that it does not need an output inverter. Also, if the UPS's battery voltage is matched with the voltage the device needs, the device's power supply will not be needed either. Since one or more power conversion steps are eliminated, this increases efficiency and ...
The medium-duty 1930 A-series trucks received the all-new 278.7 cu in (4.6 L) FB-3 six-cylinder engine, with overhead valves and seven main bearings. This was complemented by larger versions of the same engine and was built until late 1940 (as the FBB), [ 7 ] the line-up being expanded downward by the smaller FA-series (later FAB) in 1933.
The standard engine for the C3500HD was the 5.7 L V8 with the 7.4 L V8 as an option; the 6.5 L turbodiesel was introduced as an option for 1992. [12] The engines were paired to the 4L80E 4-speed OD automatic and the NV4500 5-speed manual transmissions, the latter being the sole transmission option for the 5.7 L V8.

For 1978, square headlights replaced the previous models' round ones on higher-trim-package models, such as Lariat and Ranger, and became standard equipment for 1979. Also for 1978, the Ford Bronco was redesigned into a variant of the F-Series pickup; 1979 was the last year that the 460 engine was available in a half-ton truck.
The Bucyrus MT6300AC is an off-highway, ultra class, two-axle, diesel/AC electric powertrain haul truck designed and manufactured by Bucyrus International Inc. in the United States. The MT6300AC is Bucyrus' largest, highest payload capacity haul truck, offering one of the largest haul truck payload capacities in the world, up to 400 short tons ...
The eighth generation of the Ford F-Series is a line of pickup trucks and light- to medium-duty commercial trucks produced by Ford from 1987 to 1991. While the previous generation cab and chassis were carried over with minor changes to the vent windows, interior trim mounting locations, and floor pan shape on the transmission hump, the 1987 model was more streamlined, and maintenance items ...
