An adjustable power supply device

Abstract

The invention mainly relates to an adjustable power source device. The adjustable power source device comprises an upper casing and a lower casing which can be matched with each other for coverage, wherein a bottom opening of the upper casing and a top opening of the lower casing are in abut joint to make the upper casing and the lower casing which are assembled together have a hollow accommodation chamber formed in the two, a lower circuit board fixed on the lower casing and an upper circuit board fixed on the upper casing are arranged in the hollow accommodation chamber, a socket or a plug of a connector is arranged on the top face of the lower circuit board, the other one is arranged on the bottom face of the upper circuit board, the socket and the plug are plugged, an input interface part mounted at the front end of the lower circuit board receives AC current and a voltage signal source needing amplification, and an output interface part mounted at the back end of the lower circuit board provides an output voltage of the voltage signal source after amplification.

Description

technical field [0001] The invention relates to a general hanging power supply device, in particular to an electric power supply device which cooperates with a testing machine or a laboratory to provide power when an integrated circuit or a circuit to be tested is tested. Background technique [0002] In the field of conventional integrated circuit design and packaging and testing, each wafer merchant or packaging and testing merchant is different because of the timing of equipment procurement and the emphasis on the source of each test machine model of the test equipment supplier. Most equipment manufacturers The voltage source output by the test equipment can only provide a voltage source such as 0-50V or 0-40V or 0-20V. With the diversification of electronic products, such as the LED driver integrated circuits on the market, if you try to test the operating voltage value of this driver integrated circuit or the overvoltage protection voltage value OVP and other similar vo...

AI Technical Summary

Problems solved by technology

With the diversification of electronic products, such as the LED driver integrated circuits on the market, if you try to test the operating voltage value of the driver integrated circuit or the overvoltage protection voltage value OVP and other similar voltage test items, the voltage they require is completely It may be between 40-100V, that is to say, the voltage source output by the test equipment of the current equipment manufacturer cannot completely cover all the voltage ranges actually required
