1.產品名稱:光電二極體(Photo Diode, PD)
Photodiodes are sensitive to a specific range of light wavelengths, corresponding materials are selected for sensing depending on the wavelength of the Emitting Device The materials are divided into silicon-based PD (sensing wavelength between 400 ~1100 nm) and compounds PD (sensing wavelength between 480~650nm / 900~1700nm), coupled with coating technology, can achieve sensing effects in specific wavelength to meet the differentiated needs of customers.
2.產品名稱:光電晶體(Phototransistor)
It consists of emitting device, sensing device and signal amplification to complete the switch of electricity-optical-electricity, and the input and output are completely electrically isolated, realizing one-way transmission of input signals and preventing the output signal from affecting the input . It is often used in optical Coupler signal isolation switch and signal transmission.
3.產品名稱:光閘流體(Photo Triac)
(1). 零點觸發 (ZC) :
For 60Hz AC power supply, there are sixty sine wave cycles and sixty crossing points to zero voltage. When turning on or switching off at this moment, it doesn’t quite occur the sparkle in order to extend the life of switch connection node.
If using the light triggering thyristor with much shorter conducting time characteristics as a control switch which drives external connection node at the zero crossing, it is able to surpass those of longer reaction time in conventional electromagnetic relay which is unable to reach in the zero-cross switching.
(2). 非零點觸發 (NZC) :
What differs from ZC is that the NZC allows to output voltage at any time of AC sine wave. Therefore, because the output voltage wave form is not always the competed sine wave so it can control the phase angle to output different power.
