Voltage protectors, also can be called surge protectors or voltage stabilizers, are another electrical device that Pugao(Plannter) offers, in addition to MCBs and changeover switches. They protect electronic devices from unexpected voltage fluctuations, that is what we called surges or spikes, ensuring a more stable power supply.
Key Features
Pugao(Plannter) uses advanced technology to design and manufacture voltage protectors. These devices have a wide input voltage range, offering protection from 90-280V, making them highly adaptable to various power grids. When a surge current occurs, the protector can withstand 40kV, avoid the occurrence of large peaks, and respond to abnormal voltage in less than 1 nanosecond.
On our products, you can see clear indicator lights to prompt power on, protection activation and wiring fault warning, which is very convenient in use. The housing is made of flame-retardant material for enhanced safety.
Key Functions
Over/Under Voltage Protection:
-
The Voltage Protector continuously monitors the supply voltage in real time.
-
Automatically disconnects the circuit when voltage exceeds or drops below preset limits.
-
Prevents damage to appliances caused by unstable power supply.
Time Delay Function:
-
Built-in delay feature avoids frequent switching during voltage fluctuations.
-
Allows safe reconnection after power stabilizes, protecting compressors and sensitive equipment.
-
Delay time can be adjusted based on application needs.
Adjustable Settings:
-
The Voltage Protector supports adjustable overvoltage, undervoltage, and current parameters.
-
Users can set protection thresholds according to different load requirements.
-
Improves flexibility for residential, commercial, and industrial applications.
Indicator Lights:
-
Equipped with LED indicators to show working status clearly.
-
Displays conditions such as normal operation, fault, and protection mode.
-
Helps users quickly identify system status and troubleshoot issues.
Installation and Maintenance
Before installation, the first thing to consider is the installation location. To provide whole-house protection, Pugao(Plannter) recommends installing the main voltage protector at the main distribution board. For point protection, plug the voltage protector directly into a wall outlet, and make sure it's not daisy-chained with another power strip or extension cord.
After installation, it can protect electrical appliances. All available sockets can be used, but the maximum load capacity of the equipment must not be exceeded. Sensitive and expensive electronic equipment can be given priority, especially some audio equipment and medical equipment.
During the entire use process, the voltage protector basically does not require any maintenance. The key operation you can pay attention to is to regularly check the status indicator light. There are no user-serviceable parts inside, and they have a limited lifespan, with performance degrading with each surge they absorb. Therefore, even if there are no obvious faults, they will eventually need to be replaced after extended use. This is a natural phenomenon of use.
Types and Applications
Single Outlet Protectors:
-
A Voltage Protector in single outlet form is designed for individual appliances.

Easy to install and ideal for residential use.
Plug-in Surge Protectors:
-
Used for multiple devices such as computers, routers, and office equipment.
-
Combines voltage protection with surge suppression for added safety.
-
Suitable for home offices and small commercial setups.
-
Portable and convenient for temporary or flexible installations.
Panel-Mounted / Heavy Duty:
-
Installed in distribution boards or electrical panels.
-
Designed for whole-system protection in industrial and commercial environments.
-
Handles higher current loads and provides centralized protection.
-
Ideal for factories, server rooms, and large electrical systems.
