Optocoupler: High-performance optocoupler with high switching speed and high withstand voltage.
Rustproof: The screw is made of high toughness material, which is not easy to break and slide.
Fire-Proof: The shell is crafted from high-temperature tolerant flame-inhibiting material. Upon exposure to high temperatures, the sign retains its shape and smoothness, with seams remaining intact.
Long Service Life: chip, strong performance and long service life.
Copper Material: High-purity copper base plate is used to effectively increase the thermal conductivity by 1.5 times.
