Description

Technical Field

[0001] The utility model relates to the technical field of programmable power supplies, and particularly relates to a connection component for a programmable power supply. Background Technique

[0002] Programmable test power supplies are controlled by microcomputers, with advanced technology, full-program control, full-button operation, small size, light weight, and convenient to carry. They can be used both in laboratories and on-site. A programmable power supply is a high-precision power supply with programmable control functions. It can flexibly output various parameters such as different voltages and currents according to the needs of users, and has characteristics such as high precision, good stability, and fast response speed. The control mode of the programmable power supply is based on programming, and the power supply can be controlled by writing programs, setting parameters, etc. Through a computer or other controllers, users can easily monitor and adjust parameters such as the output voltage, current, and power of the programmable power supply in real time, realizing high-precision and high-stability power output. Programmable power supplies have many characteristics and functions. They can provide various output modes, automatic testing, remote control and monitoring functions, and can flexibly meet various complex testing and development requirements. In addition, the output voltage range of the programmable power supply is relatively wide, which can meet the needs of various different devices and application scenarios. Programmable power supplies are widely used in various fields that require high-precision power output, such as the testing of electronic components, circuit board testing, LED lamp testing, etc. In addition, in high-requirement application scenarios such as medical equipment, aerospace, and communication equipment, programmable power supplies are also widely used. Inside the programmable power supply, there is a group of three-stage control tubes. This group of three-stage control tubes can play a protective role in the circuit. When the current of the power supply is released, this group of three-stage control tubes can shunt and suppress the current, decomposing the large current into small currents. When outputting, the programmable power supply will combine and integrate these small currents through the control of the microcomputer and release them again, and the output voltage will have very little loss, reducing the loss of electric energy in the transmission path. In order to keep the circuit stable and the on-off normal, the programmable power supply is also provided with an operational amplifier decoupling capacitor, which can effectively prevent circuit oscillation and keep the circuit stable. In addition, in order to protect the coil in the programmable power supply, the internal device of the programmable power supply also contains a back electromotive force breakdown adjustment tube to avoid damaging the triode and causing damage to the coil due to excessive electric energy released instantaneously.
