ZGGH10-24

General                                                                                 
          ZGGH10-24 Modular Power Supply SPD consists of a power module and a base, used for the secondary or tertiary protection of + — - and - — PE of DC systems. It is connected between the DC power supply and system equipment in series or in parallel. It can prevent the equipment from the impulse surge and transient overvoltage caused by the outside environment (such as lightning, EMI, etc.) or by the system (such as switching effects of the system, startup or shutoff of the inductance and capacitance load, etc.).
Features                                                                                 
          1Anti-reverse protection on the module;
          2Low residual voltage;
          3Overtemperature protection;
          4Failure indication and centralized remote signalling alarm dry contacts;
          5Enclosure IP20, UL94 V0.
