Huawei ETP48100-B1-100A is a modular AC/DC converter with as many as 4 power inputs, each with MAX 25 A. It is capable of converting 220 V / 110 V AC power into -48 V DC power. The device has two R850G2, making its total output power can be 100 A. Huawei ETP48100-B1-100A has many protections, so the rectifiers show very high efficiency.
TheHuawei ETP48100-B1-100A has a wide input voltage range of 100V - 240V. In addition, it also features a wide operating temperature range from -40°C to 75°C, so you can use it in almost any conditions. Easy installation and maintenance is conditioned by the possibility of hot exchange of rectifier blocks. The design of the device is very versatile and has a wide range of applications, plus it is very well thought out, which guarantees space saving. The device is also characterized by a remarkable efficiency of the rectifier (>96%), which saves electricity in an ecological way. In addition, Huawei ETP48100-B1-100A has support for ambient temperature monitoring.
The ETP48100-B1 is designed to convert 220V public mains to -48V constant voltage. The ability to use two internal power supplies provides up to 100A of -48V output current. all functional units have a standard 1U size and can be installed in a 19" rack or cabinet.
