Most
products sold in the rugged market start out as desktop or
consumer products (Commercial Off The Shelf otherwise known
as COTS). These vendors will attempt to "ruggedize" their product
to compete in the rugged market. These ruggedized COTS products
usually fail due to either temperature, mechanical shock or
vibration requirements since they were not designed to withstand
these extremes!
ETI's products start out rugged whether for COTS or full MilSpec applications. They are designed
to and meet Military Environmental Standards. ETI's products have successfully passed these tests numerous times including
Mil STDs 167-1, 810E, 901D plus surviving the vehicle mounted endurance tests in the notorious Belgium Block and the
explosive charges in the Barge tests.
ETI designs all of its products with the concept of modularity and interchangeability between
products. This includes the battery modules. For example, the standard internal battery module is used in numerous
UPS products. The external battery modules can be used with multiple versions of UPS as well.
