5. Set the load resistance to 6 Ω ±1
Ω
and the power supply voltage to 24 V.
6. Enable the load.
7. Enable the power supply and verify the current limit magnitude and auto-retry fault response waveform
as shown in Figure 4 .
Figure 4. J5/J12 = 2-3 Position, Current Limit (2.23 A), Auto-Retry Mode
8. Disable the power supply.
9. Set the current limit response mode to latch-off by installing the J4/J11 jumper in the position 1-2.
10. Set the load resistance to 6 Ω ±1 Ω and enable the load.
11. Enable the power supply and verify the current limit magnitude the latch-off fault response waveform
as shown in the Figure 5 .
Figure 5. J5/J12 = 1-2 Position, Current Limit (2.23 A), Latch-Off Mode
12. Once the device is latched-off, either the power supply or the SHDNb should be recycled to re-enable
it.
13. Change the load resistance to 16 Ω ±1
Ω
.
14. Press and release the reset switch (S1/S2) to re-enable the device from latch-off mode and verify the
recovery or restart waveform as shown in Figure 6 .
