ETP4890-A2 is an efficient telecommunications power station equipped with three R4830G rectifiers with a current of 30A. The total output current of the entire device is 90A, at 53.5V DC it gives a total of about 4800 W of power. The output voltage range is -42 ~ -58V DC (default value is -53.5V), and input voltage 85 - 300V AC (at 45 ~ 66 Hz). The maximum number of power lines is 4.
The set includes an SMU01C controller equipped with a DB 50 connector. In addition, it has an RS232/485 console port and an LCD display. It supports Huawei protocol "access network point-to-point" so it can be connected to U2000. On the front of the controller, in addition to the display, there are buttons to control, two LEDs (one informing about work, the other informing about alarm), and the entrance to the temperature sensor.
The most important features:
- SMU01C controller;
