Chroma 6304 In Lake Mary, FL, USA, model 6304, is manufactured by Chroma power supplies.
Chroma Model 6300 series Smart Electronic Load System is the state-of-the-art instrument for testing DC power sources and power electronic components. The system is configured by plugging the user selectable load modules into the system mainframe, and operated using the instrument front panel keypads or the remote controlled instructions via GPIB interface. The load modules can be programmed independently for testing multi-output DC/DC power supplies, or in parallel for testing high power application.
The 6300 family offers 4 types of modular loads with power ranging from 60 watts to 300 watts, current setting from 150μA to 60A, and voltage measurement from 0.5mV to 250V. Each load is isolated and floating, programmable in dual current ranges and measuring voltage ranges, and capable of synchronizing interface for master/slave control operation. The load can be operated in constant current, constant resistance,constant voltage, or constant power mode.
The 6300 can simulate a wide range of dynamic loading applications. The loading waveform is user programmable in slew rates, load levels, duration, and conducting voltage. The load can also be controlled via external analog control voltage, or signal generator to simulate specific application requirements. Furthermore, up to 100 sets of system operating status can be stored in battery backup SRAM and recalled instantly for automated testing application.
Real time measurement of voltage, current, and power is integrated in each 6300 load module using 15-bits precision measurement circuit. The user can perform on line voltage measurement and adjustment, or simulate short circuit test using simple front panel keypad operation. Additionally, the load module offers optional noise measurement function capable of detecting 20MHz noise via differential mode input without the need of a scope.
