JT634 series electronic load is functioned with 500KHz high-speed synchronous sampling, DSP technology, powerful dynamic test and multi-aspect intelligence analysis. All these are fully integrated into auotmatic test function, which makes JT634 series load very suitable for testing power supply when produced in large quantity. Besides, JT634 series load also possesses the features of current rising slew rate programmable, high-speed dynamic loading and programmable list function, which makes JT634 series load satisfing most of R&D requirements. Moreover, JT634 series load’s special parallel operation method can satisfy the synchronous loading requirements of multi-channels output power supply and satisfy single-channel output power supply requirement for big power.
