To construct your own dummy load
1
Obtain a connector that is compatible with the connector J3 on the
Low Voltage Power Supply.
2
Connect the following load resistors to the connector:
+5.1 V requires a 4-A load, 1.3
Ω
and 20.4 W on pins 9–12.
–5.25 V requires a 3-A load, 1.75
Ω
and 15.8 W on pins 15–18.
+15.75 V requires a 1.3-A load, 12.2
Ω
and 20.5 W on pins 5–6.
–15.75 V requires a 0.8 A-load, 19.7
Ω
and 13 W on pin 3.
3
Connect the other end of the resistors to ground pins 2, 4, 7, 8, 13, 14,
19, and 20.
