Frequently Asked Questions

How often should I service my automatic voltage controller?

We recommend a comprehensive service check every 12 months for optimal performance. However, visual inspections should be conducted quarterly to ensure there are no visible issues such as loose connections or dust accumulation.

What is the warranty period for your products?

All our standard products come with a 2-year manufacturer's warranty covering defects in materials and workmanship. Extended warranty options are available for purchase. Please contact our customer service for more details.

How do I determine the right capacity for my voltage controller?

The capacity of your voltage controller should be at least 20% higher than your total connected load to account for startup surges and future expansion. Our technical team can help you calculate the exact requirements based on your specific equipment and usage patterns.

Can your products be customized for specific applications?

Yes, we offer customization services for all our products to meet specific industrial requirements. This includes custom input/output voltage ranges, special protection features, and tailored enclosures for harsh environments. Please contact our sales team with your specific requirements.

What is the typical response time for service requests?

We aim to respond to all service requests within 24 hours. For emergency breakdowns, we offer priority service with a response time of 4-8 hours depending on your location. Our service network covers all major industrial areas across the country.
