The characteristic parameters of dc regulated power supply

The technical index of the dc regulated power supply can be divided into two categories: one is characteristic index, reflecting the inherent characteristics of dc regulated power supply, such as the input voltage, output voltage, output current, output voltage regulation scope; Another kind is the quality index, which reflects the advantages and disadvantages of dc regulated power supply, including stability, equivalent resistance, ripple voltage and temperature coefficient, etc. Battery load tester host built-in memory, read U disk storage records are available, and do not need to carry the computer, single machine can work, use the computer to print the report in the future. With voltage current calibration correction function, can at any time for instrument calibration correction measurements, guarantee the accuracy of measurement. Comprehensive tester does not need to discharge battery accurately measure the internal resistance and estimate capacity, found behind the battery in advance, to ensure the safe operation of the battery power supply system, and guide the battery in the correct parameters, prolong the service life of battery, alarm for abnormal condition. Characteristic parameters output voltage range conform to the working conditions of the dc regulated power supply, can be normal work of the output voltage range. Battery load tester host built-in memory, read U disk storage records are available, and do not need to carry the computer, single machine can work, use the computer to print the report in the future. With voltage current calibration correction function, can at any time for instrument calibration correction measurements, guarantee the accuracy of measurement. The index's upper limit is made up of input voltage and the minimum input required by the output voltage difference, and the lower limit is determined by the internal reference voltage value of the dc regulated power supply. (2) the input - output voltage difference which characterized under the condition of guarantee the normal work of the dc regulated power supply, is allowed to enter the output value, the voltage difference between its value mainly depends on the dc regulated power supply pressure indicators of internal adjustment transistor. (3) the output load current range output load current range is also known as output current range, within the scope of the current, dc regulated power supply should be able to ensure that they meet index standard given by the index. (4) the minimum input an output voltage difference which characterized under the condition of guarantee the normal work of the dc regulated power supply, the voltage difference between the input and output the required minimum value.
