TISP61089BSD High Voltage Ringing SLIC Protector
‘1089 Section 4.5.11 - Current-Limiting Protector Testing (Continued)
The test generator has a voltage source that can be varied from zero to 600 V rms and an output resistance of 20 ? to each conductor. Table 4
shows the range of currents conducted by the TISP61089BSD.

‘1089 Section 4.5.12 - First-Level Power Fault Testing
Table 5 shows the nine tests used for this section. The TISP61089BSD will survive these peak current values as they are lower than the
TISP61089BSD current-time ratings.

NOTES: 1. If the equipment contains a voltage-limiting device or a current-limiting device, tests 1, 2 and 3 are repeated at a level just below
the thresholds of the limiting devices.
2. Test 5 uses a special circuit with transformer coupled a.c. and capacitive feed.
3. Tests 1 through 5 are requirements and the equipment shall not be damaged after these tests.
4. Tests 6 through 9 are desirable objectives and the equipment can be damaged after these tests.
‘1089 Section 4.5.13 - Second-Level Power Fault Testing for Central Office Equipment
Table 6 shows the five tests used for this section. Columns 9 and 10 show the prospective currents for these tests using R S values of 25 ? and
40 ? . The two most stressful tests of this section are test 1 and test 2. As shown in Table 6, the peak currents for these tests are 2x17 A and
2x7.7 A respectively. With the exception of test 5, all the other tests require the series overcurrent protection to operate before the
TISP61089BSD current-time ratings are exceeded. In the case of test 2, with an R S of 25 ? , the overcurrent protection must operate within the
initial a.c. half cycle to prevent damage.
