Telecommunication Product Description Introduction: Maintaining correct incoming supply voltage to telecommunication equipment within base station sites is necessary to avert malfunctions and to increase MTBF(Mean Time Between Failures) of the equipment. Wenzhou Modern presents special-purpose AC power supply for telecommunication, the cost of it compare to the purchase of telecommunication equipment and the subsequent loss of revenue due to failure, is minimal. Applications include providing stable voltage to air conditioning units used to cool the equipment and extra protection to rectifier units enabling them to operate at nominal voltage to provide improved efficiency, minimal harmonics and extending working life. According to different of designed electric system and structure, it has specified as three phase synchronous adjustment and three phase independent adjustment.
