Chroma Programmable DC Electronic Load 6310A series is suitable for the test and evaluation of multi-output AC/DC power supply, DC/DC converter, charger and power electronic components and good for application in areas such as research and development, production, and incoming inspection. The system is configured by plugging the user selectable load modules into the system mainframe, and operated using the keypad on the front panel of the instrument or the remote controlled instructions via RS-232C, USB or GPIB interface.
The 6310A series offers 8 types of modular loads with power ranging from 100 watts to 1,200 watts, current from 0.5mA to 240A, and voltage measurement from 0.5mV to 500V. Each load is isolated and floating, programmable in dual current range and measuring voltage range, and capable of synchronizing with other modules for control operation. The load can be operated in constant current, constant voltage, constant power and constant resistance. The 6310A series can simulate a wide range of dynamic loading applications. The loading waveform is programmable in slew rates, load levels, duration and conducting voltage. Furthermore, up to 100 series of system operating status can be stored in EEPROM and recalled instantly for automated testing application. Real time measurement of voltage and current is integrated into each 6310A load module using a 15-bit precision measurement circuit. The user can perform on line voltage measurement and adjustment, or simulate short circuit test using the simple keypad on the front panel. Additionally, the 6310A series offers an optional remote controller for automated production line. The 6310A series has self-diagnosis routine to maintain instrumental performance all the time. It is also protected against OP, OC, OV, OT, and reverse polarity to guarantee quality and reliability for even the most demanding engineering testing and ATE application. The Chroma 6314A 1200W and 6312A 600W electronic load mainframes accept the user-installable 6310A series load modules for easy system configuration and fit 19" instrument rack. The 6314A holds four 63102A load modules at most to offer 8-channel 100W input load with standard front-panel inputs. It fits for testing multiple output switch power supply. Additionally, GO/NG output port is useful for UUT's pass/fail judgement on automated production line. All modules on the 6314A/6312A mainframe share a common GPIB address to synchronize and speed up the control of load modules and read-back of operating data. - Max Power: 200W, 100W×2(Dual), 30W & 250W, 300W, 600W, 1200W
