Emerson rectifier module R48-2900U illustrates rectifier module R48-2900U function
1, input 220V50Hz, working range 85~290Vac
2 、 output 42~58Vdc, software adjustable, output power 2900W;
3. Modular software flow uniformity, uneven mobility less than 3%
4, CAN bus communication, and Tatsu 48
5. It has many protections such as AC over voltage, DC overvoltage, over temperature, short circuit and so on
6, with LED working status indicator, a variety of alarm indicator function
7, module hot plug, plug and play, without any parameter settings.
8 、 module double power supply rectifier module R48-2900U characteristics:
1, wide range of input voltage power: power derating input voltage range: 85Vac ~ 176VA
2 、 no working withstand static voltage: 415Vac
3. Rated input current: less than 16A@2900W
4. Input current: less than 19A@2900W/176Vac
5 、 input shock current: <30A2, output limit power, short circuit current limit
3, hot swap, adaptive
4, double temperature limit power, over temperature protection
5 DSP, software flow and average current difference < + 1.5A module internal processor DSP flow control, average current mode, constant voltage control module - module - control failure does not affect the flow and uneven flow alarm yellow indicator lamp: current error more than 8A red light: no output or error more than 10A parallel 48 does not need to streamline the use of CAN bus, ensure that all modules can be normal communication
6, overvoltage shutdown, automatic restart
7 、 hardware overvoltage protection:
8 – – 59.5V. Need to start manually.
9. Software overvoltage protection
10. - monitor settings: 56-59V
11 - Software overvoltage protection mode has two kinds, can be selected through the background maintenance software:
12 、 A. once overvoltage lock mode
13, when the output reaches the software protection point, the module shuts down and maintains, needs the artificial intervention to be possible to restore the work;
14 、 B. two overvoltage locking mode
15, when the output reaches the point and output current software protection module is more than 5A, after shutdown after 5 seconds, if within a set time (the default is 5 minutes, can be set) occurred second times over voltage, and keep off module, the need for manual intervention to boot.
16 、 if the rectifier module output current is less than 5A (rated output 10%), the rectifier module does not shut down.
17. Manual intervention method: reset the rectifier module through the monitoring module, or reset the rectifier module from the power supply system.
18, the current slow start
19, above is the introduction of Emerson R48-2900 communication power supply products.
