<\/span><\/div><\/div><\/div>We work closely with our customers to ensure every aspect of the design is addressed, whether there is a detailed requirements specification or simply a rudimentary need, we are able to quickly develop a suitable solution.<\/p>\n
Our primary area of expertise is DC-DC power supplies for aerospace applications<\/a> operating from 28V sources. However, we are also experienced in designing for 48V, 72V and 270V input voltages for ground and airborne applications.<\/p>\n<\/div><\/div><\/div> We work closely with our customers to ensure every aspect of the design is addressed, whether there is a detailed requirements specification or simply a rudimentary need, we are able to quickly develop a suitable solution.<\/p>\n Our primary area of expertise is DC-DC power supplies for aerospace applications<\/a> operating from 28V sources.

Other input circuitry may include reverse polarity protection, inrush current limiting and bulk internal capacitance. DC-DC conversion is performed by power converter modules, output filtering is added when required. In the unlikely event that COTS modules are not suitable for an application, a component level design will be developed.<\/span><\/p>\n In addition to the basic DC to DC conversion, we can also include built-in test functions such as input over and under voltage protection, input power good indications, either visually or with electronic signals, as required.<\/span><\/p>\n<\/div> On the output side we can include:<\/span><\/p>\n<\/div> Over and under voltage detection and indication<\/p>\n<\/div><\/li> Over and under voltage protection<\/p>\n<\/div><\/li> Short circuit protection, either continuous with auto recovery or shutdown with recovery on power re-cycle<\/p>\n<\/div><\/li> Output power good indications for each output or combined, either visually or with electronic signals, as required<\/p>\n<\/div><\/li><\/ul> Requirements for industry standard I2<\/sup>C \/ SMBus power supply status can be accommodated, as can custom serial status in accordance with a customer requirement. For VME or ATX power supplies we provide SYSRESET and ACFAIL signals or ATX Power Good signals. Whatever your specific application requirement, we can implement it into your custom DC power supply.<\/span><\/p>\n<\/div><\/div><\/div><\/div><\/div> Packaging of the design is another key element. The environment, particularly the temperature, altitude and vibration in which the power supply will be used are critical design drivers. These factors have a direct impact on the packaging concepts used, the selection of components, the cooling approach and the required strength of the unit as a whole, including the mounting and securing of components within the power supply.<\/p>\n<\/div><\/div><\/div> Each custom DC power supply unit is uniquely packaged in accordance with the customer requirements. Typically, this is a custom six-sided aluminum box made from sheet metal which results in a non-hermetic unit, or machined from solid, which can be hermetically sealed. This is particularly important for ground defense applications<\/a> where units may be mounted to the outside of a vehicle and be exposed to water and dust. Whatever custom shape is required, our mechanical design team will custom fit the circuitry to accommodate the space available for the application.<\/p>\n<\/div> The units are typically finished with a chemical conversion coating, either yellow, or clear if RoHS <\/a>compliance is necessary. The units can also be painted in whole or in part with the applicable coloured paint required by your specification. For a particularly wear-resistant finish, part or all of the unit can be anodized.<\/p>\n<\/div><\/div><\/div> If you are in the market for a custom DC power supply unit for a military applications<\/a> or industrial application Viable Power can offer a solution that works for you.<\/p>\n<\/div><\/div><\/div><\/div><\/div> If you would like more information about our DC-DC Power Supply Unit design services, please feel free to contact us<\/a> at any time.
