G20DT series video signal lightning protector is a kind of commonly used surge protector. It is an important embodiment of internal lightning protection and also belongs to the category of weak current system. Dedicated to anti-lightning protection of surveillance equipment such as cameras, video switches and dividers. The low clamping voltage and fast response feature provide good suppression of various types of overvoltage pulses and guarantees all-weather normal operation of indoor and outdoor sensitive equipment.

FAQ
Q1: Can I make multiple orders and combine shipment?
A: Of course you can. We will arrange shipment per your request and in the best interest of our customers. Sometimes separate shipment is in fact faster and cheaper, we will let you know the detail reasons and have your understanding before shipment.
Q2: What is distributed (cascaded) surge protection?
A:Distributed protection, cascaded protection or coordination is the process of coordinating protection between the primary service entrance of a large facility and the internal branch distribution panels. Generally a surge protective device (SPD) with high surge handling capacity is installed at the service entrance while SPDs of lower surge ratings will be installed on the branch panels or dedicated supplies feeding sensitive equipment. This approach can be taken further to include point-of-use SPDs on long lines where they terminate to sensitive or critical equipment.
Q3:How does your company do regarding the quality control?
A: Quality is priority. We always attach great importance to quality control from the beginning to the end of the production. IQC inspects the components, the patrol inspection is done during production and all the goods to be tested 100% before leaving the factory.
