Overvoltage transient protection
Lightning, electrostatic discharge, switches and other power system transient overvoltage caused by interference may also cause damage to the transceiver, for these transient interference method can be used to bypass the protection. Bypass protection and utilization of transient suppression components (such as TVS, gas discharge tubes, etc.) will bypass harm to the transient energy
Comprehensive than similar products, a lot of stocking. Regardless of the seller and is not, please take a direct payment. Every day around 17:00 unified delivery. More than 500 orders for the production of one week in advance to book.
This product is fully designed in accordance with industrial standards. All the chips are imported chips. With anti-lightning, and anti-static shock, slew-rate drivers, effectively curb electromagnetic interference. Resolve valid signal and invalid signal is superimposed on the transmission circuit. Error-free data transfer rates of up 115200bit. Therefore, this product line using ordinary data communication data lines can be used.
