Product overview:
   This device applies to the normal manual transfer, accident transfer and abnormal operation condition transfer between service power supply with functions of post acceleration of independent back-up branch and over current protection. It adopts the technology of automatic tracking and sampling of the voltage frequency of bus ( effective measuring range is 15
55Hzas well as the unique software phase measuring technology, which effectively improve the measuring precision of the residual voltage of bus and resolves the defect of the low speed of hardware phase meausring. It provides effective guarantees for the safe and reliable transfer, especially for the accident transfer.
