Flexible Operation


List Mode Function
- Lets you generate more complex sequences of input changes with several different levels
- Up to 7 groups of list files can be saved
- Each list can contain up to 84 steps with minimum width time of 20 μs per step
- Run list mode programs remotely with application software


Transient Operation
- Enables module to periodically switch between two load levels
- Power supply's regulation and transient characteristic can be evaluated by monitoring supply's output voltage under varying combinations of load levels, frequency, duty cycle, and slew rate
- Transient operation can simulate these conditions
- Transient mode up to 25 kHz in CC mode
- Run transient operation programs remotely with application software


Automatic Test Mode
- Up to 100 different sequences can be linked to run steps of various operating modes and loading conditions
- Each sequence can also be programmed with upper and lower limit Pass/Fall criteria
- When applied in production testing, you can easily judge whether device test parameters are within specification limits and adjust process according to the Pass/Fail verdict
- Test modes to validate the OCP/OPP


CR-LED Mode
- Use load's unique CR-LED operating mode to test LED drivers
- Function allows users to configure LED's operating resistance and forward voltage, along with voltage range, to simulate loading behavior of typical LEDs
- Figure - LED I-V Curve (Right)
- Vd = Forward voltage of the LED
- Rd = LED's operating resistance
- Vo = Operating voltage across the LED
- Io = Operating current across the LED
Remote Control and Programming


Battery Test Function
- Built-in battery test function with voltage level, capacity level, and timer stop conditions
- Measures ampere-hour (Ah)
- Uses CC mode to calculate battery capacity using fixed current load discharge
- Users can specify cut-off voltage level, capacity level, and time stop conditions


Voltage-on (Von) Latch Operation
- Control input turn on state for DC electronic load by configuring Von latch function
- Can be used to start and stop discharging of battery or other power source at specified voltage levels
- Built-in rise and fall time measurement can measure rise or fall time from specified start and stop voltage level of measured input without need for oscilloscope
- Built-in rise/fall function can also be used as internal timer to count how long input has been enabled


Adjustable Slew Rate
- In CC mode, users can control rate or slope of change in current in transient response test
- Set slew rate to as slow as 0.001 A/ms or as fast as 2.5 A/μs, depending on model and selected current range
- Slew rate can be set via front panel or programmed remotely
