Principle and application experiment of semiconductor optoelectronic devices
Semiconductor optoelectronic devices include LEDs, laser semiconductors, light receiving devices, optocouplers (optocoupler relays, optocoupler circuit breakers), optical communication devices, etc.
Experiment 1: Optocoupler Relay Test
The optocoupler relay is a non-contact switching device with relay characteristics that uses semiconductor components instead of electrical contacts as a switch. It is widely used in computer peripheral interface devices, numerical control machinery, remote control systems, industrial automation equipment, precision instruments, etc. When testing optocoupler relays, high current is the main cause of damage to its internal components. Some products will generate a large surge current at the moment of switching on, so it is very important to ensure a certain current redundancy during the experiment.

Application 3: Laser test
The laser test has extremely high requirements on the power supply, which is a constant current power supply. The traditional power supply defaults to the CV loop priority, and the speed of suppressing the current overshoot at the moment of startup is slow. ITECH’s programmable DC power supplies have CC/CV priority function. Users can adjust the loop speed according to the test requirements, and choose the test of high voltage in CV mode, or the CC priority mode without current overshoot.

- IT6900A DC power supply(model special for no current overshoot, switch+line structure, low ripple, low noise)
Sensor principle verification and detection experiment
A sensor refers to a device or device that converts non-electricity into electricity that has a definite relationship with it. It usually consists of sensitive parts and conversion parts. When the active sensor is applied and detected, it needs an power supply to complete the detection experiment.
