About This
- 【Automatic Power Switching】Designed for seamless power transfer between AC Input 2 (Utility or Shore Power) and AC Input 1 (Inverter or Generator). When AC Input 2 is active, load automatically switches to it; when power is lost, it instantly transfers back to AC Input 1, ensuring uninterrupted operation.
- 【Fast & Stable Transfer】Operates at AC 90–135V, 50/60Hz with a maximum current of 15A. Transfer time is less than 30 milliseconds (0.03s), fast enough that most smart devices and computers experience no power interruption during switching.
- 【Reliable 4-Relay Design】Built with four high-power SPST relays to eliminate arcing issues found in DPDT designs. Both Live and Neutral lines switch simultaneously for enhanced safety, while all Ground wires remain continuously connected internally.
- 【Durable Waterproof Enclosure】Features an IP68-rated, flame-retardant housing made of polycarbonate with a silicone rubber seal and 304 stainless steel screws. Engineered to withstand indoor or outdoor environments, offering superior moisture and dust protection.
- 【Pre-Wired for Easy Installation】Comes with pre-installed cables: AC Input 1 – 19" (0.5m) NEMA 5-15P plug; AC Input 2 and Output –19" (0.5m) 14AWG 3-core cables. Compact inline design makes mounting quick and hassle-free.

SMART HOME FAQ
Yes — many modern devices support multiple platforms.
Matter-certified devices can work across Alexa, Google Home, and Apple HomeKit at the same time.
Not always.
Smart bulbs, plugs, cameras, and video doorbells are often easy DIY installations, while full security systems may need professional setup.
Many devices still work manually or through local control.
You may lose remote app access, but locks, lights, and thermostats often continue basic functions.
Security depends on the device and setup.
Use strong passwords, trusted brands, firmware updates, and secure Wi-Fi for better protection. Privacy and unauthorized access are common concerns in smart homes.
Most homeowners start with:
Smart Security Cameras
Smart Door Locks
Smart Thermostats
Smart Plugs
Video Doorbells
Yes.
Smart thermostats and smart plugs help reduce wasted energy by automating heating, cooling, and power usage.
