200 Amp 3 Phase Automatic Transfer Switch ATS Switches

Nowdays, the technology changes with each passing day, the equipment of power system are being developed in the direction of centralized control and intelligence, that is, the weak current (electron) controls the strong elertricity. We developed the new generation of automatic transfer switching equipment by using advanced international technologies according to user's actual needs. This product employs the latest microcomputer control system as the core component; it has advantages of electromagnetic compatibility, Strong immunity, long-term reliable operation, is equipped with a large screen LCD backlight display, provides user-friendly man-machine interface, convient and intelligent operation. Therefore, it is an ideal automatic transfer switching equipment, also is the most perfect upgrading product among the similar produats at home, ir marks a new epoch in the development toward the intelligence and networking.

1.Ambient air temperature should be within -25℃~+40℃, the mean value within 24h should not exceed +35℃

2.Atmospheric conditions: the air should be clean, the relative humidity should not exceed 50% at +40℃, higher relative humidity is permissible at lower temperature condition, for instance, RH may reach 90% at +20℃, but should take the condensation into consideration that may caused by temperature change.

3.The altitude of installation site should not exceed 2000m, it should be used indoors

4.The installation site should be free of strenuous vibration or impact, no corrosion affecting the electric elements

5.If beyond the abovementioned conditions, please negotiate with the manufacturer when placing the order

6.If the switch is intended for offshore oil or nuclear power station, shall enter into an additional technical agreement
