Air Cooled Power Assembly

Grid linked Power Equipment

  • Excitation Systems
  • Power Conditioning
  • Hydrogen Production

Dynex engineers are engaged in providing tailored power assemblies for hydro dam excitation, power factor correction and rail traction. Dynex are also part of several hydrogen production projects powered from grid distribution.

Collaborating with renewable generation partners and electrolysis system providers, Dynex are working towards topologies and system architectures that provide a power source bespoke to the generation of Hydrogen from a stochastic source, improving the efficiency of production, as well as preventing premature degradation of electrodes due to fluctuations in power.
