Product functions
Comprehensive test Comprehensive test display, measure DC current, measure DC voltage, measure AC voltage and measure ripple voltage, and calculate the voltage stabilization accuracy, the stabilization accuracy, the voltage ripple coefficient and the ripple coefficient, .
The voltage stabilization accuracy measures the voltage stabilization accuracy when the AC input voltage changes within the rated voltage range, the load current changes between ~ the rated value, and the DC output voltage is at any value within the adjustment range.
Current stabilization accuracy measures the current stabilization accuracy when the AC input voltage changes within the rated voltage range, the output current is at any value ~ the rated value, and the charging voltage changes within the specified adjustment range.
Ripple accuracy measures the ratio of half of the difference between the peak value and the valley value of the pulsation in the DC voltage output by the charging device to the average value of the DC output voltage, and calculates the steady voltage ripple coefficient and steady current ripple coefficient. .
Efficiency measures the ratio of AC rated input power to DC output power of the charging device. Efficiency measurement display measures AC voltage, measures AC current, measures DC voltage, measures DC current, and calculates the input power, output power and efficiency.
Harmonic measurement Current harmonic measurement mainly displays the status of ~ harmonics, including harmonics or fundamental harmonic true effective value, harmonic content rate, total harmonic distortion rate and other parameters.
