Surge & Voltage Protectors — Shield Your Appliances from Unstable Power.
Protect motors, PCBs, power supplies, and electronics from voltage spikes, surges, and fluctuations. Plug-in protection with voltage monitoring and automatic disconnection, or transient surge protection, depending on the model.

Two Types of Protection, One Goal — Keep Your Devices Safe.
Voltage protectors handle ongoing fluctuations. Surge protectors handle sudden spikes. Together, they offer complementary protection.
SP01A Surge Protector
230V · 4000W · 6kV / 26kA surge protection
SVP06A Digital Voltage Protector
230V · Over/under-voltage cut-off · Automatic reconnection
SVP02A Non-screen Voltage Protector
16A / 3600W · 5–6 minute restart delay · Plug-in operation
SVP01A Digital Voltage Protector
16A / 230V · LCD voltage display · Delayed automatic recovery
Voltage Protection
Continuous monitoring, automatic disconnection and reconnection for appliances such as refrigerators, air conditioners, freezers and pumps.
Surge Protection
Fast response to transient surges from lightning activity, grid switching and motor starts, for computers, TVs and routers.
Complementary Protection
Match protection to the electrical risks your equipment faces. Ask us about options for high-value appliances.
Why Your Appliances Fail Early — And How a Voltage Protector Helps.
Many customers think a power outage is harmless. But repeated voltage fluctuations can quietly shorten appliance life.
When a power outage happens, everything stops. You wait for power to return. But months later, some appliances fail early — and you wonder why. Repeated abnormal voltage can put extra stress on motors, PCBs, power supplies, sensors and electronic control systems.
Depending on local grid conditions, homes may experience over-voltage, under-voltage, frequent outages, voltage instability and sudden power restoration.
Take a refrigerator.
It runs 24/7 and its compressor starts and stops many times a day. A voltage protector continuously monitors input voltage, cuts power when it goes out of range, and reconnects after voltage returns to a safe range and any configured delay has elapsed. This helps reduce exposure to unsafe voltage and frequent restarting.

Power Outages
Power restoration can expose appliances to abnormal supply conditions.

Unstable Voltage
Over-voltage and under-voltage can affect everyday appliance operation.

Motors & Electronics
Repeated abnormal voltage can place stress on internal components.

Refrigerator Protection
Monitor the supply and disconnect when voltage is outside the safe range.

Automatic Recovery
Restore power after voltage returns to normal and the model’s restart delay expires.

Safe Everyday Use
Check the rated load, use a secure wall socket, and keep the protector away from water and heat.
Voltage Protector vs Surge Protector — They Solve Different Problems.
Many people think they are interchangeable. They are not. One handles sudden spikes; the other handles ongoing fluctuations.
| Feature | Surge Protector | Voltage Protector |
|---|---|---|
| Electrical Risk | Transient high voltage from lightning activity, grid switching or motor switching | Sustained over-voltage, under-voltage and ongoing fluctuations |
| Protection Method | Limits or diverts transient over-voltage | Disconnects power outside the safe range and restores it after recovery |
| Typical Equipment | Computers, TVs, routers and sensitive electronics | Refrigerators, air conditioners, freezers and pumps |
| Main Value | Helps protect sensitive electronic equipment from surges | Helps protect motor-driven and compressor-based equipment from abnormal voltage |

Don’t ask “which one is better?” Ask “what electrical risk does my device actually face?” If transient spikes are the main risk, choose surge protection. If voltage is chronically unstable, a voltage protector is more practical. In complex environments, they provide complementary protection for high-value appliances.
