DC power supply technical indicators which
3, the limit index (1) the maximum input voltage
Is to ensure that the DC power supply safe operation of the maximum input voltage.
(2) the maximum output current
Is to ensure that the safe operation of the regulator to allow the maximum output current.
DC power supply specifications can be divided into two categories: one is the characteristics of indicators, reflecting the inherent characteristics of DC power supply, such as input voltage, output voltage, output current, output voltage adjustment range; the other is the quality indicators , Reflecting the advantages and disadvantages of DC power supply, including stability, equivalent resistance (output resistance), ripple voltage and temperature coefficient.
1, the characteristic index (1) output voltage range
In line with the DC power supply operating conditions, the normal working output voltage range. The upper limit of this indicator is determined by the maximum input voltage and the minimum input-to-output voltage difference, and its lower limit is determined by the reference voltage inside the DC regulated power supply.
(2) Maximum input - output voltage difference
This indicator characterizes the voltage difference between the maximum input and output allowed under the normal operating conditions of the DC regulated power supply. The value depends mainly on the voltage regulation of the DC regulated power supply.
(3) minimum input - output voltage difference
This indicator characterizes the voltage difference between the minimum input and output required to ensure proper operation of the DC power supply.
(4) Output load current range
The output load current range, also known as the output current range, in this current range, the DC power supply should be able to ensure compliance with the indicators given by the indicators.
