Technical specifications and characteristic indexes of DC stabilized power supply
DC Voltage Regulator An electronic device that provides a stable DC power supply to a load. DC regulated power supply power supply is mostly AC power supply, when the AC power supply voltage or load resistance changes, the DC output voltage of the regulator will remain stable. DC regulated power supply with electronic equipment to high precision, high stability and high reliability of the direction of the development of electronic equipment power supply put forward high requirements.
Technical Specification
The technical indexes of DC regulated power supply can be divided into two categories: one is the characteristic indexes, reflecting the inherent characteristics of DC regulated power supply, such as input DC regulated power supply voltage, output voltage, output current, output voltage adjustment range; the other is the quality indexes, reflecting the advantages and disadvantages of DC regulated power supply, including stability, equivalent internal resistance (output resistance), ripple voltage and temperature coefficient and so on.
Characteristic indicators
(1) Output voltage range. DC regulated power supply operating conditions in line with the output voltage range that can work normally. The upper limit of this indicator is specified by the * large input voltage and * small input - output voltage difference, while its lower limit is determined by the DC regulated power supply internal reference voltage value.
(2) Maximum input-output voltage difference. This indicator characterizes the DC regulated power supply to ensure that the normal operating conditions, the maximum allowable input - output voltage difference between the values mainly depends on the DC regulated power supply internal adjustment transistor voltage withstand indicators.
(3) Minimum input - output voltage difference. This index characterizes the minimum input - output voltage difference required to ensure that the DC regulated power supply under normal operating conditions.
(4) Output load current range. Output load current range is also known as the output current range, in this current range, DC regulated power supply should be able to ensure compliance with the indicators given in the specification.
