A DC wide voltage reliable use circuit tooling

Abstract

The invention provides a DC wide voltage circuit tooling, which includes two connecting clips, which are respectively arranged on the input side and the output side of the tooling, and the first connecting clip arranged on the input side is used to electrically connect the input of the tooling and an external DC stabilizer. The output of the piezoelectric power supply, the second terminal clamp arranged on the output side of the tooling is used to electrically connect the output of the tooling with the input of the lamp to be tested or the drive circuit board of the lamp to be tested; the tooling also includes a circuit driver board, and the circuit driver board It is provided with a first relay, a second relay, a voltage comparator, a first resistor, a voltage regulator tube, a voltage sampling circuit for collecting the input voltage of an external DC stabilized power supply, a first switch circuit, a second switch circuit and three terminal Regulator circuit. The invention utilizes a certain simple circuit combined with a relay, an operational amplifier, and a MOS tube to solve the problem of expanding the input range of an external DC stabilized voltage supply, and can ensure that testers can normally perform circuit-driven tests under any circumstances, and improve Improve work efficiency and reduce costs.

Description

technical field [0001] The invention relates to a DC wide-voltage reliable use circuit tooling, in particular to a simple circuit tooling that can be used in a wider voltage range and can be used safely even when the voltage is raised. Background technique [0002] Lamp lighting can be seen everywhere in modern society. Lamps used in all walks of life have different purposes, especially in portable lamps, the typical voltages used are 6V, 12V, 24V, and sometimes low-voltage lamps In the high-voltage environment, it is used in an urgently needed environment, and when it is aging, the equipment is not enough, and various voltage lamps are connected to one voltage for aging. At this time, the lamps with low voltage cannot be connected to places with high voltage. , it is easy to burn out the circuit board due to excessive voltage, so in order to make the lamps to be tested match the corresponding test equipment and reduce the cost of purchasing test equipment, it is necessary t...

[0002] Lamp lighting can be seen everywhere in modern society. Lamps used in all walks of life have different purposes, especially in portable lamps, the typical voltages used are 6V, 12V, 24V, and sometimes low-voltage lamps In the high-voltage environment, it is used in an urgently needed environment, and when it is aging, the equipment is not enough, and various voltage lamps are connected to one voltage for aging. At this time, the lamps with low voltage cannot be connected to places with high voltage. , it is easy to burn out the circuit board due to excessive voltage, so in order to make the lamps to be tested match the corresponding test equipment and reduce the cost of purchasing test equipment, it is necessary to provide a circuit tooling that can make the lamps to be tested suitable Power input for various test equipment
