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                                                                                 
1. Anti-reverse protection on the module.
2. Low residual voltage.
3. Overtemperature protection.
4. Failure indication and centralized remote signalling alarm dry contacts.
5. Enclosure IP20, UL94 V0.
