Product Introduction
The KNS5-3S/2X four-display three-power transfer switch is suitable for AC 50/60Hz circuits with an operating voltage of AC230V. This 3 Way power transfer switch 4 display ATS features three displays and automatic voltage regulation to ensure household electrical safety and protect family members from potential hazards. It is widely used in household appliances, factories, and similar applications.
This 3 Way power transfer switch 4 display ATS offers automatic switching, adjustable values, and priority phase sequence. It automatically detects the circuit voltage and switches to the usable circuit when the voltage is too high or too low.
When the original circuit voltage returns to normal, this 3 Way power transfer switch 4 display ATS automatically switches back to the original circuit. This product has a compact structure and elegant appearance and can be installed in parallel with MCB series products.
This 3 Way power transfer switch 4 display ATS complies with the following standards: JBT 12762, JGJ242-2011.
