GR-1089-CORE Issue A.C. Power Fault testing has been comprehended in the design of the TISP61089HDM. For compliance, circuit designs
must pass both First Level and Second Level A.C. Power Fault testing.
First Level Power Fault testing requires that the equipment shall not be damaged and continues to operate correctly without disruption to
other parts of the system. In laboratory tests it has been shown that the circuit shown in Figure 3 can pass these tests without damage.
Figure 4 shows the TISP61089HDM I
TSM
rating to be above the level of GR-1089-CORE First Level tests.
Second Level Power Fault testing may result in the equipment becoming non-operational, but any component failure should not allow the
equipment to become a hazard. The system should not burn, fragment, or become an electrical safety hazard. The test data in Figure 5
illustrates that the TISP61089HDM and the B1250T are current coordinated, as the fuse interrupt time is shorter than the time it takes to
damage the TISP61089HDM package for a given current.
