Our prices are subject to change depending on supply and other market factors. We will send you an updated price list after your company contact us for further information.
Yes, we require all international orders to have an ongoing minimum order quantity. If you are looking to resell but in much smaller quantities, we recommend you check out our website
Yes, we can provide most documentation including Certificates of Analysis / Conformance; Insurance; Origin, and other export documents where required.
For samples, the lead time is about 7 days. For mass production, the lead time is 20-30 days after receiving the deposit payment. The lead times become effective when (1) we have received your deposit, and (2) we have your final approval for your products. If our lead times do not work with your deadline, please go over your requirements with your sale. In all cases we will try to accommodate your needs. In most cases we are able to do so.
You can make the payment to our bank account, Western Union or PayPal:
30% deposit in advance, 70% balance against the copy of B/L.
We warranty our materials and workmanship. Our commitment is to your satisfaction with our products. In warranty or not, it is the culture of our company to address and resolve all customer issues to everyone’s satisfaction
Yes, we always use high quality export packaging. We also use specialized hazard packing for dangerous goods and validated cold storage shippers for temperature sensitive items. Specialist packaging and non-standard packing requirements may incur an additional charge.
The shipping cost depends on the way you choose to get the goods. Express is normally the most quickest but also most expensive way. By seafreight is the best solution for big amounts. Exactly freight rates we can only give you if we know the details of amount, weight and way. Please contact us for further information.
Q: What is a surge protective device (SPD)?
A: A surge protective device, also known as a surge protector or lightning arrester, is an electrical device designed to protect sensitive equipment and electrical systems from voltage spikes or surges caused by lightning strikes, power grid fluctuations, or other sources.
Q: How does a surge protective device work?
A: Surge protective devices work by diverting excess voltage from a surge to the ground, preventing it from reaching and damaging connected equipment. They typically use metal oxide varistors (MOVs) or gas discharge tubes to absorb and dissipate the surge energy.
Q: What types of equipment can benefit from surge protective devices?
A: Surge protective devices are beneficial for a wide range of electrical and electronic equipment, including computers, televisions, home appliances, HVAC systems, telecommunications equipment, industrial machinery, and any other devices susceptible to voltage surges.
Q: Where should surge protective devices be installed?
A: Surge protective devices should be installed at the main electrical service entrance to protect the entire building or facility. Additionally, they can be installed at distribution panels or near sensitive equipment to provide localized protection.
Q: Are surge protective devices the same as power strips?
A: No, surge protective devices are not the same as power strips. While power strips may include surge protection features, not all power strips offer adequate surge protection. It's important to look for specific surge protective devices that meet industry standards and provide sufficient protection.
Q: How long do surge protective devices last?
A: The lifespan of surge protective devices can vary depending on factors such as the type and quality of the device, the severity and frequency of surges, and environmental conditions. However, it is generally recommended to replace surge protective devices every 3 to 5 years to ensure continued protection.
Q: Can surge protective devices protect against lightning strikes?
A: Surge protective devices can help protect against lightning-induced surges, but they cannot provide complete protection against a direct lightning strike. In such cases, additional measures like lightning rods and grounding systems are necessary to divert the lightning energy safely to the ground.
Q: Can surge protective devices be used in conjunction with uninterruptible power supplies (UPS)?
A: Yes, surge protective devices can be used in conjunction with uninterruptible power supplies. The surge protective device protects against voltage spikes, while the UPS provides backup power during outages or brownouts. Together, they offer comprehensive protection for sensitive equipment.
Q: Are all surge protective devices the same?
A: No, surge protective devices can vary in terms of their surge handling capabilities, response time, clamping voltage, and overall performance. It's important to choose surge protective devices that are specifically designed and rated for the intended application and that meet recognized safety standards.
Q: Can surge protective devices be installed by homeowners, or is professional installation required?
A: Some surge protective devices are designed for easy installation and can be installed by homeowners following the manufacturer's instructions. However, for more complex installations or whole-building protection, it may be advisable to seek professional assistance from qualified electricians or technicians.
