Specifications

To construct your own dummy load
1
Obtain a connector compatible with the connector on the Low
Voltage Power Supply.
2
Connect the following load resistors to the connector.
+
5.1 V requires a 3 A load, 1.7
Ω
and 15 W on pin 15, 17, or 19.
+
15.75 V requires a 1.3 A load, 12.2
Ω
and 20.5 W on pin 11 or 13.
With the fan operating,
−
15.75 V requires a 0.6 A load, 26.25
Ω
and
9.5 W on pin 5 or 7.
Without the fan operating,
−
15.75 V requires a 0.8 A load, 26.25
Ω
and
13 W on pin 5 or 7.
3
Connect the other end of the resistors to ground pins 2, 4, 6, and 8.
