INTRODUCTION
1.1 General Description
The SLD-series Electronic Load modules are designed to test, evaluate and burn-in multi-
output DC power supplies and batteries. Each SLD-series Electronic load module is a two-
channel programmable DC Electronic load. Each module has its own control and display with
CC, CR. CV, Dynamic, and Short operation modes, 150 sets Store/Recall memory, and GO/NG
check sorting. The modules operate in the SLM Mainframe by manual control or by
programmable GPIB and RS-232 remote control.
The SLM Mainframe accommodates up to four SLD-series modules, except for the 550W
module, for combination testing requirements. The size of the 550W module, a dual load,
requires two mainframe bays in the mainframe, and can be installed in channels 1 & 2, 2 & 3 or
3 & 4 of the SLM-4 mainframe. The channel identification will be the rightmost bay. Figure 1-1
through Figure 1-4 show the power contours for each model of the SLD-series Electronic Load:
