ZGDD20 (TY)

Mã sản phẩm : 1490069934

In a metal case, the ZGDD20 (TY) Single-phase Power Supply SPD has a beautiful appearance and convenient installation and connection, characterized by the overcurrent protection, trip of thermal fusing, and failure indication. In case of lightning surges on incoming services, the lightning protection components inside the SPD will enter into a “Low Impedance” state with a response speed of nanosecond level, to discharge the lightning current to the earth; the overvoltage caused by lightning will be limited within a voltage range in which electric equipment can withstand, to ensure secure operation. It is mainly suitable for lightning protection of power supply used in the postal and telecommunications services, banks, broadcast television, airports, chemical industry, 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 Maintenance Installation

1 Before installation, check if the SPDis damaged. And then use the multimeter (definitely not the tramegger) tomeasure if the resistance values among L, N, and PE are normal: The resistance valuesbetween L/N and PE should be infinite, and that between L and N should begreater than 1MΩ.

2 After fixing the SPD, connect it to the powersupply of protected equipment according to the marks on the connectingterminal. The insulated copper wire with the cross-sectional area ≥ 6mm2 and withstand voltage not lower than AC500V should be used, asshort as possible.

3 After all the connections, switch on the powersupply if everything is alright. The indicator turns to “Green”, showing thenormal working of SPD.

Usageand Maintenance

1 The circuit is set with thermal fusing and overcurrent protection. Duringnormal working, the indicator shows “Green”; when the SPD components degradeeven are out of use, the internal temperature controlled switch isautomatically detached, and the indicator shows “Red” for alarming.

2 The product needs nospecial maintenance during normal use. Because it always has uninterruptedpower supply, periodically check its working conditions, especially afterlightning. If it is found that the indicator shows “Red”, the SPD should bechanged.

3 Thegrounding 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 moreor less. When the grounding wire PE opens, the SPD will lose its protective effect.
