ATS Dual-Source Distribution Box

Name: ATS Dual-Source Distribution Box
Brand: Jiangsu Zhongshun Electric Co., Ltd.
Availability: InStock

The ATS transfer switchgear continuously monitors the power quality of both utility feeds. The controller can be configured in three operating modes: primary on one circuit, primary on the second circuit, or no primary. When either the first or second circuit is designated as the primary, automatic transfer and restoration are enabled. If the primary feed fails or its power quality falls short of the load’s requirements, the control system automatically switches the load to the backup power source. Once the primary feed is restored to normal conditions, the control system automatically reverts the load to the primary feed.

Product Features

▪ The grid‑connected switchgear features a high degree of automation: unit startup and shutdown, synchronizing and closing, load shedding and tripping, and load sharing are all performed automatically, enabling the power generation and supply system to operate without on‑site supervision.

▪ The grid‑connected switchgear operates stably, and its operating procedures are easy for personnel to master.

▪ Comprehensive protection features: reverse power protection, overcurrent protection (implemented by the controller), generator set trip‑out protection for faults, overload protection (independent of the switch), voltage fault protection, and an emergency stop function.

▪ Suitable for AC power supply systems with a frequency of 50 Hz and a rated operating voltage of 400 V or less. This switch features dual protection—electrical interlocking and mechanical interlocking—and provides over‑voltage and under‑voltage protection for any one or more phases in a three‑phase system, as well as overcurrent and short‑circuit protection.

▪ Widely used in critical power-supply locations such as high-rise buildings, hospitals, shopping malls, banks, chemical plants, and military facilities, the ATS transfer switchgear is designed for switching between two utility power sources.
