Flexistax D1000
FLEXISTAX D1000 DC-DC Power Solution up to 1,000W

Flexistax 950W DC-DC power solution
The Flexistax series complements the Powerstax custom power range and is specifically designed to meet the need of companies seeking to reduce their time-to-market, lessen capital investment and minimise the risk often associated with the outsourcing of their unique power supply requirements.
The Flexistax D1000, D950 and D750 are ideal for use in the telecoms, automotive and industrial markets or any application where a rapid, cost-effective and efficient custom solution for high power DC-DC conversion is needed.
Prototypes can be supplied in just 4 weeks from Powerstax’s own ISO9001 approved design, development and production facility at Farnborough, Hants. UK. The Flexistax D750 is a 750W DC-DC power conversion system developed specifically for applications where standard off-the-shelf solutions do not exist. While the Flexistax D1000 provides a similar specification at a higher power of 1000W and the D950 at 950W.
This rapid design and delivery time is achieved by the experience, resources and using a modular approach, centred on the the versatile Powerstax F501 full brick DC-DC converters.

In a highly efficient arrangement, two Powerstax, versatile F501 full brick DC-DC converters of 500W were coupled with a custom 2 phase boost converter and customer specified connectors. (see fig left) to present a complete bespoke solution.
The patented high efficiency topology and extremely flexible design of the F501 dc-dc converter modules means that standard items can be easily and quickly optimised for efficiency. This ensures a system efficiency of 85% and a much lower level of heat dissipation, which allows the open construction unit measuring 150mm x100mm with a max height 25mm including connections (6in x 4in x1in) to be cold wall mounted with no forced air cooling required.
The standard Flexistax D950 and D750 have a wide and variable 11 - 36Vdc input and a constant output between 12 and 48V. Utilising a simple, custom developed boost converter integrated into the design provides the boost in input voltage when conditions require.
The Flexistax D950 is ideal for use in vehicle mounted applications, the telecoms, automotive and industrial markets.
