Charging Model: 21429783 High Frequency charger technology differences and frequency charger With the continuous development of technology, a lot of computers, new technologies in the field of power electronics, a new concept to the charging machine industry and other similar products in the IT industry. in front of the charging machine compared with previous products, both in the main performance, the appearance of size, site environmental adaptability and reliability ESD5550, significant progress has ESD5330, some indicators even a qualitative leap, This is especially true for medium-sized charger charger Model: 3634778 power input connector (1) First make sure before connecting the charger with the rated input voltage and the grid voltage are the same. (2) charger input power for three-phase four-wire ESD5500E, which received three three-phase transmission line (FireWire), yellow and green wire is the ground wire. (3) the charger is connected to the external network through the power cable. To ensure safety, the power required to connect to external networks to install power circuit breaker and insurance, the capacity of the circuit breaker is about 2.5-3 times the rated input current.
