You don't have to worry anymore! This wall charger provides surge protection against electrical spikes. Three complementary Surge Protection Circuits, TVS+MOV+GDT, work together to respond in less than 1Ns, and have minimum energy-absorbing capacity of 1080 Joules. It truly provides great protection of your precious plugged-in devices. Specifications: - Input Voltage: AC 100-125V - Max Power Rating: Max 10A/1250W - USB Port Output: DC5V, total 2.4A Packing List: - 1x Multi-Outlet Wall Charger with dual USB ports - 1 x User Manual POWRUI 3- Level Complementary Surge Protector Circuit Electrical Surge, Surge Protection Components & Surge Protection CircuitsWhat causes an electrical surge? In stormy weather, when thunder happens close to the transmission line, the conveying circuit will create induced surge voltage. This can also occur when a large electric device is turned on in the power circuit. Both types of induced surge voltage can interfere the electric devices connected. The first type can damage the devices. Frequently used surge protection components Surge protectors can be added to the power circuit to prevent the damage. The surge protectors are constructed with different types of surge protection components. The most frequently used ones are MOV, GDT and TVS. MOV has medium energy absorbing capability and response time, so it is widely used in simple surge protection circuits. GDT has large energy absorbing capability but longer response time; TVS has response speed less than 1Ns with small energy absorbing capability. All three of them are used together to construct professional surge protection circuits. POWRUI 3-Level Surge Protection CircuitPOWRUI is one of the few Surge Protector makers which uses TVS, MOV and GDT to make 3-Level Surge Protection Circuit that absorbs the energy in steps, providing the best protection of the electrical devices from voltage spikes. When the power surge occurs, TVS responses within 1ns to suppress the unwanted voltages to the safe threshold. Then after several ns, MOV starts to continuously absorb energy. Within a few hundred ns, GDT works to ground a large amount of surge voltages, then triggers the circuit breaker to break the circuit and completely protect the devices. The advantage of this kind of circuit is large energy absorbing capability which could reach 1,000 – 10,000 joules with <1ns response time. But the cost is high. Other Brands 1-Level Surge Protection CircuitMost of other surge protector makers use 1-level MOV parallel circuit, that connects multiple MOV components with surge protection functions to certain joules. The advantage is simple circuit and low cost which can meet the surge protection needs to under 1000 joules. But the energy absorbing capability is low with slow response time, that can only be used on basic surge protector. Product information
