How to maintain the switch to extend service life?

Test switching monthly, clean dust, and check contacts. Annually, engineers calibrate interlocks, upgrade programs, and replace worn parts.

What is the function of the Dual Power Transfer Switch?

It automatically or manually switches to backup power (e.g., generator) when main power fails, ensuring continuous supply for key equipment.

Product Q&A

Q:How to avoid power backfeeding during installation?

The switch has built-in mechanical and electrical interlocks, so no additional device is needed. Strictly distinguish between common (N) and standby (R) power to avoid phase sequence errors.

Q:How to troubleshoot 'light on but not switching'?

Check if set to manual (switch to auto), adjust delay parameters (0-180s), or check sampling line contact. If trip light is on, check for overload or mismatched circuit breaker current.

Q:Is it compatible with generators and UPS?

Yes, supports mains-generator and mains-UPS modes. Link generator start signal (0-30s delay) and configure surge protection at UPS input/output to prevent overvoltage damage.

Q:What information is needed for a detailed quotation?

Provide product name, model, specification, quantity, current, voltage, power, and specific use case for an accurate quote.

Q:Difference between PC-class and CB-class switches?

PC-class offers fast switching (50-250ms) for critical loads like hospitals but needs external protection. CB-class integrates circuit breaker functions for industrial lines but has slower switching (2000-3000ms).
