Frequently Asked Questions
Q: What is a Dual Power Automatic Transfer Switch and how does it work?
A: A Dual Power Automatic Transfer Switch (ATS) monitors two power sources — such as a solar system and the mains grid. When one source becomes unavailable or drops below acceptable levels, the ATS automatically switches to the alternate source within 1–2 seconds, ensuring a continuous and uninterrupted power supply to your connected loads.
Q: Is this transfer switch compatible with both single-phase and three-phase systems?
A: Yes. This ATS supports single-phase 220V and three-phase 400V electrical systems, making it suitable for a wide range of residential and commercial solar or grid applications operating at 50Hz or 60Hz.
Q: What operating current ratings are available for this switch?
A: This Dual Power Automatic Transfer Switch is available in operating current options ranging from 63A to 125A, allowing you to select the rating that best matches your system's load requirements.
Q: Can I manually control which power source is active?
A: Absolutely. In addition to full automatic switching mode, this ATS includes a manual mode so you can choose your preferred power source directly — ideal for testing, maintenance, or specific operational scenarios.
