Prodigit provides a very flexible range of Plug-in Electronic Load module and Mainframe to meet your testing requirements.
Plug-in Electronic Load units have power rating from 75W to 300W.
Modules are installed from the front of the mainframe.
The 3310 series has CC, CR, CV, dynamic and short modes, it is most commonly used for R&D, Quality control, and ATE systems. The 3320 series has CC, and short mode, it is suitable for inspection, production, and burn-in.
Voltage/Current and Wattage ratings for the 3310 and 3320 series modules are shown in the specification chaRt below.
Determine power requirements in watts and use the above table to determine which module(s) is (are) required. For example: a 12V 20A power supply would require a 300W module. A dual output power supply would require two modules.
The lower current rating in the 3310 and 3320 series Electronic Loads provides higher programming resolution and minimizes load noise effects to a power supply. Load noise order figures are listed below :
Selecting the proper mainframe :
For single load applications select Prodigit's 3302 Mainframe. This mainframe accepts all 3310 and 3320 series plug-in modules.For two or more loads requiring dynamic load testing,the 3300A mainframe should be selected. The 3300A accepts up to four 3310 series plug-in modules.
The 3301 Mainframe should be used for static load testing.It accepts up to four 3320 series plug-in modules. Selecting the proper mainframe: For single load applications select Prodigit's 3302 Mainframe. This mainframe accepts all 3310 and 3320 series plug-in modules.
The 3300A Mainframe has both GPIB/RS232C interface with Listen/Talk capability. The 3301 Mainframe has GPIB Master/Slave interface with Listen. There is no GPIB programmability if a 3310 series Plug-in unit is used in a 3301 Mainframe. Only front panel manual control is functional in this case. The Master/Slave function in the 3301 mainframe functions with only one GPIB address. To control up to eight plug-in modules there is a Master / Slave cable to connect a Master 3301 Mainframe to a Slave 3301 Mainframe.In this case, only one GPIB cable and GPIB address is required. Please refer to the 3301 Mainframe operating manual for more detailed information.
The 3302 single Mainframe accepts all 3310/3320 series Electronic Load Plug-in units with GPIB. The GPIB function is Listen/Talk for 3310 series and Listen only for 3320 series Plug-in units.
