NOTE: Performance is typical and based on operation at 23°C (73°F) ambient and nominal input voltage. This product is designed for use in a normal conditioned laboratory. Operation at higher ambient temperatures will result in decreased cooling performance. Operation above 27°C (80°F) will have a significant impact on low-temperature operation.

Due to continuous product improvement, specifications are subject to change without notice.
