Huawei ETP48100-B1-50A 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 to -48 V DC power. The device has two R850G2 modules, making its total output power up to 100 A. Huawei ETP48100-B1-50A has many protections, so the rectifiers show very high efficiency.
The Huawei ETP48100-B1-50A 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, making it suitable for use in almost any conditions. Easy installation and maintenance is facilitated by the possibility of hot swapping rectifier blocks. The design of the device is very versatile and has a wide range of applications, additionaly, it is very well thought out and guarantees to save space. The device is also characterized by a remarkable efficiency of the rectifier (>96%), which saves on electricity in an ecological way. In addition, the Huawei ETP48100-B1-50A has ambient temperature monitoring support.
The ETP48100-B1 is designed to convert 220V public grid to -48V constant voltage. The ability to use two internal power supplies provides up to 100A output current of -48V all functional units have a standard 1U size and can be installed in a 19" rack or cabinet.
