1) _{Cooling capacities at nominal / float voltage are rated at external temperatures of +35°C and +50°C respectively. Float voltage is defined at 27 VDC}
2) _{Calculated heating capacity is rated at external temperature of -40°C, nominal voltage, and ΔT = -45°C.}
3) _{Controller function shall not operate the external fan during heating mode.}
4) _{The highest environmental protection level requires an external shroud and is defined as the protection level for the enclosure.}
5) _{Rating for unit without protective shroud.}
6) _{Max ripple 5%.}
Note: The specified performance of any Laird cooling unit is dependent on how it is handled and incorporated into the final product. This includes elements such
as the system design, insulation design, and assembly method. While Laird Technologies is able to provide general guidelines based upon our experience, it is ultimately
the responsibility of the device manufacturer to validate each product and its performance for its intended use.
