Electrical Voltage Surge Protector

Pugao(PLANNTER)specializes in producing Electrical Voltage Surge Protector, real-time monitoring of the voltage status, encountering over-voltage or under-voltage automatically and quickly cut off the power, effectively extending the service life of the equipment. The products support OEM/ODM customization and are supplied directly from Chinese factories and are widely used in home, office, medical and industrial control systems.

As a professional manufacturer and supplier, offers Electrical Voltage Surge Protectors at affordable prices. It has a rated current of 40A/63A and a rated voltage of 220V/230V. It is easy and quick to install, rail-mounted, fully mountable in a standard distribution box, and is housed in a flame-retardant material. It can be easily connected to home or industrial circuits and is suitable for circuit protection in homes and small factories.

Note: Please make device connections according to the connection type. Please adjust the overcurrent, high and low voltage setting values of the device according to the operating current and voltage values of the load. Otherwise, the device may cause damage.

Technical Features

Dual-display design: Input voltage and output voltage can be seen at a glance, which is good for visual judgment of current status and equipment power supply status.

Programmable thresholds: We can set the over/under-voltage value and delayed recovery time according to the pre-programmed equipment to avoid frequent switching.

Adoption of high insulating material: The Electrical Voltage Surge Protector adopts flame retardant shell and high voltage resistant insulating material, which has high safety coefficient and long service life.

Key Considerations for Selecting a Surge Protector

Choosing the right Electrical Voltage Surge Protector requires understanding several technical parameters to ensure your sensitive equipment is fully shielded from unpredictable grid fluctuations. As an expert China supplier, PUGAO (Plannter Electric) recommends evaluating the following factors:

1. Clamping Voltage (Voltage Protection Level)

This is the maximum voltage the protector allows to pass through to your equipment during a surge.

• Safety Threshold: A lower clamping voltage indicates better protection. Our protectors feature programmable thresholds (e.g., 230V to 300V) so you can precisely set the limit your equipment can handle.
• Equipment Matching: Ensure the clamping voltage is lower than the insulation withstand voltage of your connected appliances to prevent dielectric breakdown.

2. Response Time

In the event of a spike, every millisecond counts. A high-quality Electrical Voltage Surge Protector must act before the surge reaches your internal components.

• Millisecond Triggering: Our devices are engineered for rapid disconnection, typically responding within 20ms to 50ms depending on the fault type.
• Instant Isolation: Faster response times effectively prevent the "first wave" of a surge from damaging delicate semiconductor circuits in computers and medical devices.

3. Protection Coverage

Evaluate what specific risks the device covers to ensure comprehensive system stability.

• Over/Under Voltage: Not all surges are "high." Sustained low voltage (brownouts) can burn out motors in air conditioners and pumps just as easily as a spike.
• Overcurrent & Leakage: Comprehensive units also include current monitoring and surge suppression to guard against internal circuit faults and atmospheric lighting effects.

4. Types of Surge Protection

Understanding the installation "Zone" helps in selecting the correct Electrical Voltage Surge Protector for your facility:

• Rail-Mounted (Type 2/3): These are installed directly in the distribution box. They are the ideal choice for home, office, and industrial control systems, offering centralized protection for multiple branch circuits.
• Point-of-Use: Smaller devices designed for individual high-value assets.
• Industrial-Grade: Units housed in flame-retardant, high-insulating materials specifically designed for factory environments with heavy inductive loads.

5. Maintenance and Recovery Features

A critical characteristic of modern protectors is their ability to restore power automatically.

• Auto-Reset Function: Look for protectors that feature a programmable delayed recovery time. This prevents the "flickering" effect where power rapidly cuts in and out, which can be more damaging than a single outage.
• Visual Monitoring: Dual-display designs allow maintenance personnel to quickly verify the health of the input power without needing external multimeters.

FAQ

What is the difference between a power strip and a surge protector?

A power strip merely provides extra outlets, while an Electrical Voltage Surge Protector actively monitors and interrupts the circuit during voltage spikes or drops to prevent hardware burnout.

What should I look for when buying a surge protector?

Look for adjustable voltage thresholds, high-quality flame-retardant housing, and a high interrupting current rating (such as 40A or 63A) that matches your total load.

Do surge protectors wear out?

Yes. Over time, repeated exposure to voltage surges can degrade the internal components. High-quality protectors with durable insulating materials last longer, but they should be inspected periodically for operational accuracy.

Do I need a surge protector for all appliances?

It is highly recommended for appliances with sensitive motors or control boards, such as refrigerators, medical equipment, and industrial CNC systems, as these are most vulnerable to unstable voltage.

Display and Buttons

1 - SET Button:This button is used to save after setting/changing Over-current values & high/low voltage setting values and error

wait time.

2 - UP Button: Increase the required value.

3 - Down Button: Reduce the required value.

4 - Manual On/Off Button: Used to turn off the device output. When in this state, the screen shows “off,” and the device will not perform an automatic reset. Press this button again to turn the device back on for normal operation (under non-fault conditions).

5 - Current Display

1st Display Group: During normal operation, this section displays the input (mains) voltage value. The screen remains steadily lit when there is no fault, and it flashes in the event of a fault (over-voltage or under-voltage). During programming, it shows the corresponding setting values, such as over-current, high/low voltage thresholds, error delay, and reset delay.

6 - Voltage Display

2nd Display Group: In normal working conditions, this section shows the current value. The screen remains steadily illuminated when there are no faults, and it blinks if an over-current condition occurs. During the programming phase, this display indicates the numeric values for the corresponding parameters.

7 - LED Indicators:

A>: Illuminates when an over-current fault is detected.

V>: Illuminates when a high-voltage fault occurs.

V<: Illuminates when a low-voltage fault occurs.

Out: Lights up when the device begins output operation.

Connection Diagram

The neutral and phase wires from the main power supply should be connected to the “N” and “L” terminals labeled as the device’s Input.

The neutral and phase lines for the equipment to be protected from over-voltage and under-voltage should be connected to the “N” and “L” terminals located in the Output section of the device.
