Emerson R48-1800A Functions and Features 1. The hot-swappable rectifier adopts the harmless hot-swappable technology. The output and input of the hot-swappable rectifier module have soft start units, which will not cause system output voltage disturbance when the module is inserted into the system. It takes less than one minute to replace a module. 2. Digital current-sharing rectifier module adopts digital current-sharing technology, without the need of monitoring module, the flow can be automatically shared between the rectifier modules, and the imbalance of the current is less than ±3%. 3. Input power limit control The rectifier module adopts the power limit control method according to the change of input voltage and output voltage. The transition point is 176V(return difference is less than 2V). When the input voltage is from 176Vac to 300Vac, the module can output the highest power; When the input voltage is 85Vac ~ 176Vac, it can ensure the load requirement and the reliable operation of the module at the low input voltage. The relationship between the output power and the input voltage at 45ºC is described as follows: 176Vac input, module * output power is *** rated power, i.e. 1740W; 110Vac input, module * output power is 50% rated power, i.e. 1050W; 85Vac input, module * output power is 44.4% of rated power, i.e. 800W.
