Adaptive Power Systems 4 Series Modular DC Loads

Rated Power: 75W - 300W
Input Voltage: 60V, 250V, 500V
Input Current: up to 60/ch
Number of Inputs: 1 through 8

The Adaptive Power Systems 4 Series consists of a 44M04 mainframe capable of supporting one through four DC load modules.  Both single and dual input DC load modules are available allowing up to 8 load channels to be installed in the 44M04 four slot 19" wide mainframe. For LED power supply development and test, several special LED simulation load modules are available in the 41D/42D family of LED Load modules.  All 4 Series models share common features and capabilities and support either 60V, 80V, 250V or 500V of DC input voltage. Programmable fast current slew rates allow for dynamic testing of power supplies.  For power requirements higher than 1200W, refer to 5 Series or 5VP Series Loads instead.
