The “Hardened”
labeled LBH21-Series
units (as shown in Fig 2.2.1a) are
designed for office and wiring closet
environments and factory
floor/Industrial applications. Using
special thermal techniques and a
sealed rugged metal case for heavy-
duty industrial applications no air
inflow is required for cooling, so the LBH21-Series resist dust, dirt,
moisture, smoke and insects. Choices of models for external AC or
internal DC power are available. Ambient operating temperature is -25°C
to + 60°C depending on the power source used. Storage temperature
rating is -40°C to + 100°C.
