A DC system typically consists of TRUs (Transformer Rectifier Units), batteries and distribution, either as separate units or combined together dependent on the user requirements.
The TRU can either be from the 3RC range of 12 pulse thyristor rectifiers or the 3RP range of equipment that utilises switch-mode rectifier modules.
Valve regulated lead acid batteries are used to support ships essential DC supplies via output circuit breakers.
Batteries of various sizes can be selected to meet the user’s required load and autonomy time.
The distribution typically consists of output circuit breakers and charger/battery isolators.
Gresham power Electronics also supply Ni-Cd Battery Charger Assemblies for use on submarines. These are combined assemblies or separate chargers and battery boxes. The assemblies have extensive monitoring for alarm and fault conditions.
With over 80 years designing, manufacturing and supplying power supplies for some of the most demanding applications, Gresham has a strong reputation for service and support.
We offer a wide range of both standard and custom power supplies with many items readily available from stock.
