Current Read-back 

The load current levels and load status can be set from the front panel of each load module 

or over the remote control interface. During testing, load input voltage and load current can 

be read back but the current read back will typically display the average current level unless 

the dynamic current frequency setting is low enough. An analog current monitor output is 

provided to allow capturing of dynamic current on a digital storage scope or data recorder. 

3.5

 

Analog Input Mode 

A set of analog inputs is provided at the rear panel of the mainframe to allow analog 

programming of load current using a function or arbitrary waveform generator.  This allows 

any current profile within the performance envelope of the DC load to be used for perform 

dynamic load testing beyond the built in dynamic CC mode.  

Note:

 This mode is supported in Constant Current (CC) and Constant Power (CP) modes 

only.

Rise/Fall load current slew rate control, and High/Low load level. 

•

 

Controllable load current slew rate of load level change,  

•

 

Load ON/OFF switch change and power supply turn ON. 

•

 

Short circuit test with current measure capability. 

•

 

Dedicated over current and over power protection test functions 

•

 

Automatic voltage sensing and external sense. 

•

 

Full protection from over power, over temperature, over voltage, and reverse 

polarity. 

•

 

Variable fan speed control for quieter operation
