TDI Power | DC-DC Converter Modules

TDI power produce DC-DC converter solutions for a wider range of applications. Often, an application will already have a DC power source available but need to supply power to equipment requiring a differnt voltage. Sometimes this will just be a simple change in voltage or sometimes there may be a need to provide a more accurate and stable voltage from a variable voltage source such as a battery or fuel cell.

  • Mercury DC-DC converter modules offer hot plug capability and suit redundant power arhitectures.
  • Open frame high efficiency multi output converters provide flexible solutions for data center applications.
  • Solutions can also be packaged into Environmentally Sealed enclosures to suit the most onerous environment.

With input voltages up to 750V and a wide range of packaging options TDI power has the capability to efficiently customise  solutions for a wide range of applications.

Lead has been determined to be a hazardous substance and the use of tin/lead solders are being restricted by government laws and regulations such as the European Union's RoHS Directive (Restriction of Hazardous Substances).
Initial and operating costs can generally be reduced and system reliability increased by incorporating a relatively simple DC UPS as an integral part of the data processing or communication equipment.
Improved components, technology and packaging / cooling concepts have reduced the size (watts/cubic-inch), weight (watts/pound) and initial cost (dollars / watt) of power support with improved reliability and reduced maintenance (i.e., lower new system goals of smaller, lighter and cheaper, along conversion products. When implemented properly, these can reduce operating cost.
Great opportunities for reduced design cycle time and improved performance are presented through the use of standardized cooling topologies that can be employed across various through the use of standardized cooling topologies that can be employed across various power power
TDI has developed several alternative equipment design and construction techniques for highly reliable power conversion, compatible with increasing environmental stress levels. The availability of this type of equipment opens up new alternatives for system cost and reliability optimization.
HASS is especially productive in power conversion equipment, where component stress levels are typically more aggressive than found in other products. TDI has been instrumental in establishing HASS as a viable, high value-add production process.
As the number of IFE being designed for commercial aircrafts increases, there is also an increasing need for power supplies (PSU) for these systems. Powering IFE is not a trivial task and requires special methods due to specific electrical and safety requirements.
