Input Connections
1. Prior to connecting the 5Vin DC source, it is advisable to limit the source current from 5Vin to 1A
maximum. Make sure 5Vin is initially set to 0V and connected as shown in
Figure 4
.
2. Prior to connecting the 12VBAT DC source, it is advisable to limit the source current from 12VBAT to
10A maximum. Make sure 12VBAT is initially set to 0V and connected as shown in
Figure 4
.
3. Connect voltmeters V1 at TP81 (5Vin) and TP83 (GND) to measure 5Vin voltage, V2 at TP82 (VBAT)
and TP24 (GND) to measure 12VBAT voltage as shown in
Figure 4
.
4. Connect a current meter A1 between 12VBAT DC source and J21 to measure the 12VBAT input
current.
