All Your Questions

Here are some frequently asked questions about the TOSUNlux Surge Protection Devices (SPDs):

Type 1 SPD: These surge protectors are designed to be permanently linked and installed between the secondary of the service transformer and the line side of the service disconnect overcurrent device (service equipment). They primarily serve to safeguard electrical system insulation levels from external surges brought on by lightning or utility capacitor
Type 2 SPD:  These surge protectors are installed after the main breaker panel or in a sub-panel, protecting one or several circuits from internal surges. They are usually installed within the consumer unit to protect the electrical installation, but different types of SPD are available to protect the installation from other incoming services, such as telephone lines and cable TV

1. Familiarize yourself with the types of SPDs available, such as Type 1, Type 2, Type 3, and Type 4.
2. Assess the risk of lightning strikes and discharge capacities.
3. Identify the location of the SPD within the electrical distribution and the facility’s geographic location.
4. Determine the maximum continuous operating voltage (MCOV), voltage protection rating (VPR), nominal discharge current (In), and short circuit current rating (SCCR) associated with the application.
5. Choose an SPD with an appropriate voltage protection level based on equipment immunity and availability requirements.
6. Consider cascaded SPDs with a proper surge current rating for each location to provide superior suppression for a service panel or critical load.
7. Choose an SPD with a short-circuit current rating (ISCCR) that is not lower than the maximum prospective short-circuit current at the connection points of the SPD assembly.
8. Select an SPD with the right voltage rating to avoid SPD failure.
9. Choose a circuit breaker according to the short circuit current of the building where the SPD is installed.

Surge Protective Devices (SPDs) are designed to protect electronic equipment from power surges and line noise interference. They work by limiting transient voltages and diverting surge currents. When a transient voltage occurs on the protected circuit, an SPD limits the transient voltage and diverts the current back to its source or ground. SPDs remain passive until a line voltage exceeds the turn-on voltage of the SPD’s internal components. When that occurs, SPD components become conductive and shunt excess current away from the line, typically to a grounding conductor. The remaining Let-Through Voltage passes downstream along the circuit. SPDs are made up of various components, each with their own strengths and weaknesses. Industry standards provide the levels of performance a given SPD must meet, and the class or type defines the application for which an SPD is suited.

How to Choose the Right Surge Protection Devices(SPDs)?

In our technologically-driven world, electronic devices have become an integral part of our daily lives. From smartphones and laptops to home appliances and sophisticated office equipment, our reliance on these devices is undeniable. However, with the ever-increasing prevalence of power surges and electrical fluctuations, protecting these valuable investments has become a crucial concern. This is where surge-protecting devices step in, acting as the first line of defense against unexpected power surges, safeguarding our electronics, and ensuring their longevity. In this article, we will delve into the essential factors to consider when choosing the right surge protector to meet your specific needs.

How to Choose the Right Surge Protector?

Choosing the right surge-protecting device is essential to ensure the safety and longevity of your electronic devices. Here are the key points to consider when making your selection:
·     Surge Protection Rating: Look for surge-protecting devices with a high surge protection rating, measured in joules. A higher rating indicates better protection against powerful surges. Aim for at least 600 joules or higher for basic protection.
·     Clamping Voltage: The clamping voltage represents the threshold at which the surge protector starts diverting excess voltage. Lower clamping voltage indicates better protection. Aim for a clamping voltage of 400 volts or less.
·     Number of Outlets: Assess the number of outlets you need to accommodate all your electronic devices. Ensure there are enough outlets to plug in your equipment without the need for additional power strips.
·     Type of Outlets: Consider the types of outlets offered by the surge-protecting device. Some models provide standard outlets, while others offer USB ports or specialized outlets for specific devices.
·     Response Time: The response time indicates how quickly the surge-protecting devices react to a power surge. Look for models with response times measured in nanoseconds for instantaneous protection.
·     Indicator Lights: Surge protectors with indicator lights provide a visual cue when the protection components are active and if the unit is still functioning correctly.
·     Warranty: Check for a warranty offered by the manufacturer. A longer warranty period typically indicates a more durable and reliable product.
·     Safety Features: Look for surge-protecting devices with safety features like automatic shutdown or overload protection to prevent electrical fires or damage to your devices.
·     Brand Reputation: Research the reputation of the surge protector brand. Choose reputable brands known for manufacturing reliable and high-quality surge-protecting devices.
·     Building Wiring Quality: In areas with poor electrical wiring, consider adding whole-house surge protection in addition to individual surge-protecting devices for added protection.
