6G–28
Absolute Maximum Ratings =25
Stresses in excess of the Absolute Maximum Ratings
can cause permanent damage to the device. These are
absolute stress ratings only. Functional operation of the
device is not implied at these or any other conditions in
excess of those given in the operational sections of this
document. Exposure to Absolute Maximum Ratings for
extended periods of time can adversely affect reliability.
6G–29
Electrical Characteristics =25
Minimum and maximum values are testing require-
ments. Typical values are characteristics of the device
and are the result of engineering evaluations. Typical
values are for information purposes only and are not
part of the testing requirements.

The following information refers to the SSR Recommended Operation Conditions on the previous page.
1) Both relays on with equal load currents. For single relay operation, refer to the LH1530 Recommended Operating Conditions graph.
2) Both relays on with equal load currents. For single relay operation, refer to the LH1540 Recommended Operating Conditions graph.
3) Single relay operation.
