Operating Instructions

Remote Load Control

Along with Local Load Stepping an option to remotely control the loads via external voltage is provided. This option is

provided to test an enclosed chassis where there will be no access to Local Load Stepping jumpers. This control provides

variable wattage steps anywhere from 0W to 146W using external voltage source.

In order to use the remote load control feature, set the Local Load Stepping jumpers labeled V CNTRL for all the VPX

supply voltages that need to be remotely controlled. Local Load Stepping on the VPX supplies that are not set for remote

control can still work in local mode. Connect an external 0V to 5V variable PSU to pins 12 and 13 on DBSUB-15, where pin

12 connects to the GND, and pin 13 connects to the positive voltage. The external PSU should be able to source 20mA of

current. The graph in figure 4 shows the relationship between the load wattage and V CNTRL voltage.

Warning: Applying more than 5V to V CNTRL can overheat and damage the loads.

Note: The -12V_Aux supply is not available for remote control but can be used in local mode during remote control.
