Technology Dynamics Inc. offers a wide range of custom Water Cooled Power Supplies that are designed typically for Military shipboard applications. These robust designs however make them ideal for severe environment industrial applications where forced air cooling is not an option. Water cooled Power Supplies offer an alternative to fan cooled designs where environmental conditions restrict or preclude the use of fans. Water Cooled Power Supplies also have higher power densities than air cooled power supplies.

Available as fully contained stand alone systems or as blind mate modules which allow for Hot Swap Plug-In of the power supply modules resulting in no down time for critical applications. Our Water Cooled Power Supply Products are designed for maximum flexibility, accessibility and modularity in order to facilitate future power upgrades. Custom configurations, voltages and power levels are available, contact us for your exact needs.
