TV Power Protector 1704 is rated at 13A, used in most household appliances, preventing over/under voltage from damaging sensitive electronic equipment.
In areas with frequent lightning activity, the risk of electrical overvoltage is higher. If you want extra protection for your TV, installing a protector for your TV may be a good option.
1704 is a 220V voltage protector designed for TV/DVD. It can automatically cut off the power supply when the load is 13A to prevent the equipment from being damaged by overvoltage/undervoltage. It supports lightning protection and is suitable for home theater systems. It comes with a 1-year warranty.

Technical Notes:
Ordinary sockets continue to supply power when the voltage exceeds 300V, causing equipment to overload.
The 20kA lightning protection capability of the 1704 protector can resist 95% of induced lightning events.
In family life, we often ignore the issue of electrical safety, and always think that accidents will not happen to us. However, with more and more household appliances, the potential safety hazards of electricity use are also increasing. From large appliances such as TVs, refrigerators, and computers to small devices such as mobile phone chargers and table lamps, they all rely on sockets to obtain electricity. Once there is a problem with the socket, the consequences are disastrous.
At this time, a magical over/under voltage protector 13A 1704 appeared in front of us. If the family that suffered a fire used such a socket, perhaps the disaster could be avoided.
Power voltage protector 13A 1704 has an overload protection function. When the socket detects that the total power of the connected appliances exceeds its safe load, it will automatically cut off the power supply to prevent the socket from overheating and causing a fire.
The typical power requirements of 4K TVs are 200-400W (peak power can reach 800W). The 13A load capacity of the 1704 protector (maximum load power of 2860W at 220V) fully covers this range and can stably support the high dynamic power consumption of 4K TVs and supporting audio systems.
Key parameter verification:
Voltage range: supports 165V-255V wide input, adapting to the high requirements of 4K TVs for voltage stability (HDR display requires voltage fluctuation ≤±5%).
Overload protection: built-in two-level adjustable overcurrent protection (threshold can be set) to prevent instantaneous current shock from damaging the TV motherboard.
Electromagnetic compatibility and picture quality assurance
The 1704 protector uses silver alloy contacts and a dustproof seal design to reduce contact resistance (≤0.1Ω) and avoid screen flickering or signal interference caused by poor contact.
Supports 20kA surge absorption capacity to ensure that the HDMI interface and power module of the 4K TV are not damaged by instantaneous high voltage when lightning strikes or the power grid fluctuates.
It is recommended to use it in the following scenarios:
Unstable power grid areas: areas with frequent voltage fluctuations (±15% or more) or frequent power outages.
High-incidence areas of lightning strikes: areas with ≥40 thunderstorm days per year, which require multi-level lightning protection equipment.
High-end TV users: Precision equipment such as LED and 8K TVs are sensitive to voltage and have high maintenance costs.
Old circuit system: Aging lines can easily lead to abnormal voltage or short circuits.
The power module inside the TV mainly provides basic voltage stabilization functions, but there are limitations:
Slow response speed: The response time of ordinary power modules is about 100ms, while professional protectors can reach 25ns (4000 times faster).
Narrow voltage range: The TV power supply is usually designed for 220V ± 10%, while the protector can support 170V-275V 7.
No lightning protection: The internal circuit of the TV cannot withstand the direct lightning-induced current (up to 20kA or more)
In terms of lightning protection, Over/under voltage protector 1704 also has a perfect design, which can effectively protect household appliances from lightning damage during thunderstorms.
