Product Features and Benefits
Dynamic mode up to 25kHz
Dynamic mode operation allows the electronic load to switch between two set parameters according to a set rule. The adjustment rate and transient response of the power supply monitors its output voltage waveform under a mixture of high and low current levels, duration and ramp rate. This function can be used to test the dynamic characteristics of the power supply, for example, when a computer disk drive is running or stopped, the dynamic load mode will be able to simulate the change of its operating current.
Voltage rise/fall time test
Users can use this function of IT8800 to test the voltage rise/fall time. Enter the measure menu under config and set two voltage points. Then turn on the display on timer function, after the test is completed, the screen will display this rise/fall time. For switching power supply test, fuse test, this test is crucial.
External Analog Test
The IT8800 electronic load can be controlled by the EXT PRG (positive and negative) analog ports on the rear panel to control the load's load voltage or current. 0-10 V adjustable voltage is connected to the EXT PRG terminals to simulate 0-full scale inputs to regulate the load's input voltage and current values. The analog control interface meets the control needs of industrial production and allows you to control the output voltage through a PLC without the need for a PC.
