HERO Low Voltage Power System

VPT's new High Efficiency, Reliability Optimized (HERO) Power System is the most efficient DC-DC distributed power solution available to satisfy the unique requirements of military, avionics, and space applications.

Our new HERO power system combines a new isolated, high power DC-DC converter with a set of new, small-size point-of-load DC-DC converters in a complete system to power low-voltage devices.

As a result, the HERO Power System delivers more power, with military-grade reliability, while requiring less space and cost than any solution previously offered for your most demanding applications.

Product Overview

The HERO Power System includes two new modules from VPT:

The New DVHE Series DC-DC Converter. This converter provides up to 50 watts of power and operates 20% more efficiently than its predecessors.
The New DVPL Series DC-DC Converter. This is a non-isolated, synchronous, buck regulated converter that steps down the voltage at the point of end use. Multiple DVPLs can be powered from a single DVHE.

When these modules are used together in the HERO Power System, they deliver:

More Power. The DVHE provides 50W in a standard hermetic 30W case size at more than 90% efficiency. This is 66% more current than previous generations offered in the existing standard case size. Now you can use just a single DVHE to power multiple low voltage devices instead of deploying multiple DC-DC converters.
More Reliable Operation. All modules are available to MIL-PRF-38534 standards for use in critical reliability applications. The DVHE delivery of high power results in the need for fewer modules and fewer interconnects, which inherently increases system reliability.
Less Space and Cost. Fewer modules mean fewer square inches on a board and less cost.

All modules in the HERO Power System operate within the military temperature range of -55?C to +125 ?C with no derating of either input voltage or output power. The HERO Power System?s high power, reliable performance, and smaller space enable engineers to produce a more efficient power design overall.
