Electric Power Generators We specialize in providing product and manufacturer reviews of (and access to) the highest quality electric power generation equipment available. Here you will find portable generators, standby generators, backup generators, home portable generators, camping generators, RV generators, marine generators and industrial generators. Our complete review of available electric generator equipment is online to help you find the equipment and services that you need. We review all of the top generator brands and bring a summary of that information to you in one convenient place. Look over our pages before you buy to become familiar with each brand. We help you make an informed generator purchase decision. Home Standby / Backup Generators Home standby generators, sometimes called 'home backup generators', are generator units that are permanently installed outside a residential dwelling and are generally powered by either natural gas or propane gas.

These units are designed to provide all (or partial) electric power to a home when the utility power fails and come in several sizes and options. Several manufacturers provide home standby generators, such as: Generac, Guardian, Onan, Katolight, Coleman,.(and others). Portable Generators Portable generators are generator units that are designed to be moved from place to place and come in many sizes and power output ratings. This category includes any unit that is movable, from the handheld 'ultralite' generators to units mounted on a 'cart' that can be wheeled around a garage or jobsite.

Although larger high capacity generators can be considered 'portable' (when mounted on a trailer), we have included those in the industrial category since they generally are used in a non-residential application. Further we consider the portable generator category to be broken into (at least) two major categories; homeowner portable, and contractor / jobsite portable. These categories are may be further broken down with respect to either the engine type (air cooled or liquid cooled) and/or fuel type.

This project for sine wave generation using PWM with PIC microcontroller is described with the help of circuit diagram and source code. Pulse Width Modulation (PWM) is a technique in which the width of a pulse is modulated keeping the time period of the wave constant.

Each orbiter, based on the earlier spacecraft, was an approximately 2.5 m across. The fully fueled orbiter-lander pair had a of 3527 kg. After separation and landing, the lander had a mass of about 600 kg and the orbiter 900 kg. The total launch mass was 2328 kg, of which 1445 kg were propellant and gas. The eight faces of the ring-like structure were 0.4572 m high and were alternately 1.397 and 0.508 m wide.
