Product Description
Solid-state decoupler for cathodic protection system

Product Introduction
I produced the decoupling technology uses advanced solid metal shell , can effectively control the pipeline safety effects of stray currents or lightning alternating current on buried pipelines , extending the life of the pipeline. At the same time , but also to prevent harm and interference in the collection of stray current pipeline of human communication lines.
    Solid-state decoupling device (SSD) Series DEI company adhering to the corrosion of industrial corrosion products provide innovative tradition , using the company's own research and development of DEI 's solid-state technology . Since the SSD light weight , non-metallic shell, so it is widely used in the cathodic protection system.
    As DC isolation and AC-coupled devices , SSD is used to prevent cathodic protection current reaches a predetermined threshold voltage , while conducting alternating current induction . When the voltage exceeds the threshold voltage sought , SSD immediately switch to short-circuit mode , in order to provide overvoltage protection. When the overvoltage past , and automatically switch back to DC isolation mode. This mode of operation can be carried out many times , this is usually due to the AC fault currents or lightning currents cause . Standard voltage thresholding SSD for -2V / +2 V. The absolute value of the threshold voltage may be a voltage or peak voltage , the voltage at the switching occurs, the voltage across both ends of the spacer in the flow and exchange of the city and the peak voltage . This allows the clamp voltage across the terminals of the low SSD , very safe.
    Like most products with DEI , SSD through independent laboratory certification. Confirm compliance with all well-known American , Canadian and European standards. Inspection and certification and Demko performed by Underwriters Laboratories (Underwriters Laboratorics --- UL), thus obtained UL, CUI ( meet CSA requirements ) column name and the CE mark. After certification , SSD can be used in dangerous situations ( class 2 area )


Range of Application:
1.Pipeline potential gradient pad ( grounding pads ) decoupling
2.The device over AC fault , lightning and switching transient voltage protection ( such as: insulation joints , insulating flange )
3.For safety , for de- coupling between the different metals , these metals may in some cases generate an AC coupling.
4.In the cathodic protection system, grounding electrical equipment exchanges and direct isolation
5.To reduce the AC voltage induced occasions


Technology index:
1.Start a DC voltage (1mA)-2V / +2 V
2.Impact Flow Capacity (8/20μs) 100KA
3.steady-state current 45A
4.Leakage current ≤ 15μA
5.fault current (AC-rms / frequency / 30 cycle ) ≥ 3500A
6.Operating temperature -45 ºC ~ +60 ºC
7.Protection class IP65
