Product Introduction

The TOMZN Night Light Series TOQ7e Mini ATS is a compact, PC-level dual power automatic transfer switch designed for household power transfer between city power and backup sources such as generators or PV systems. With integrated Wi-Fi smart control via eWeLink, it enables remote monitoring and switching. When the main city power becomes abnormal, the backup source engages immediately with a switching time of less than 50ms, ensuring uninterrupted, reliable, and safe power supply. The device is rated for AC 110-120V L+N, 50/60Hz, with impulse withstand voltage of 8kV, and offers mechanical life of 5000 cycles and electrical life of 2000 cycles. Please note operational limitations: the Wi-Fi chip is powered by source A; if source A loses power, remote switching via eWeLink is unavailable. Also, the power-on state function has specific behaviors as described.
