ZGDD40 (TY)

Mã sản phẩm : 1490069906

Ina metal case, the ZGDD40 (TY) Single-phase Power Supply SPD has a beautifulappearance and convenient installation and connection, characterized by theovercurrent protection, trip of thermal fusing, and failure indication. In caseof lightning surges on incoming services, the lightning protection componentsinside the SPD will enter into a “Low Impedance” state with a response speed ofnanosecond level, to discharge the lightning current to the earth; theovervoltage caused by lightning will be limited within a voltage range in whichelectric equipment can withstand, to ensure secure operation. It is mainlysuitable for lightning protection of power supply used in the postal andtelecommunications services, banks, broadcast television, airports, chemicalindustry, etc.

Standards Complied GB 18802.1-2011 Surge protective devices connected to low-voltage power distribution systems. Part 1:performance requirements and testing methods  Installation, Usage And MaintenanceInstallation
1 Before installation, check if the SPD is damaged. And then use the multimeter (definitely not the tramegger) to measure if the resistance values among L, N, and PE are normal: The resistance values between L/N and PE should be infinite, and that between L and N should be greater than 1MΩ.
2 After fixing the SPD, connect it to the power supply of protected equipment according to the marks on the connecting terminal. The insulated copper wire with the cross-sectional area ≥ 6mm2 and withstand voltage not lower than AC500V should be used, as short as possible.
3 After all the connections, switch on the power supply if everything is alright. The indicator turns to “Green”, showing the normal working of SPD. The SPD must be grounded well, to have normal work of indicator; if the grounding resistance is overlarge or is not grounded, the normal work of indicator cannot be obtained.

Usage and Maintenance
1 The circuit is set with thermal fusing and overcurrent protection. During normal working, the indicator shows “Green”; when the SPD components degrade even are out of use, the internal temperature controlled switch is automatically detached, and the indicator shows “Red” for alarming.
2 The product needs no special maintenance during normal use. Because it always has uninterrupted power supply, periodically check its working conditions, especially after lightning. If it is found that the indicator shows “Red”, the SPD should be changed.
3 The grounding system of the SPD should be checked at any moment in normal use, especially in lightning seasons, to keep it in a good state all the time. Otherwise, the lightning protection effect of the SPD will be influenced more or less. When the grounding wire PE opens, the SPD will lose its protective effect.
