Emerson R48-1800A power module Rectifier module

Original Emerson R48-1800A communication power module

Rectifier module hot swap technology with no damage , the output and input has soft start unit , when the module is plugged into the system , it will not cause the system output voltage disturbances . Replace the module in less than one minute .

. Digital current sharing

Rectifier module adopts advanced digital streaming technology , without monitoring module , rectifier modules can be automatic current , average current imbalance is less than ± 3%.

. Input Limiter Power Control

Rectifier module according to the input voltage and output voltage changes , limit the use of advanced power control method . Transition points in 176V ( return difference is less than 2V). When the input voltage is 176Vac ~ 300Vac , the module can output the maximum power ; when the input voltage is 85Vac ~ 176Vac time , so that in low input voltage both to ensure maximum load demand , but also to ensure reliable operation of the module , the output power and input voltage relationship shown in Figure 1-5 .

Figure 1-5 rectifier output power and input voltage relationship map

45 ℃ , the output power and input voltage relationship Description:

176Vac input , the module maximum output power of 100 % of rated power , ie 1740W;

110Vac input , the module maximum output power of 50 % of rated power , ie 1050W;

85Vac input , maximum output power of the module is 44.4 % of the rated power , that is 800W.

. Output load characteristics

Input Voltage 176Vac ~ 300Vac , the module maximum output power of 1740W.

When the load continues to increase , the output voltage will drop , the output voltage is 52.7V ~ 58V , the output power constant , a maximum of 1740W, ie, the output voltage is 58V , the maximum output current of 30A; output voltage is 52.7V , the maximum output current of 33 A. The output voltage and output current relationship shown in Figure 1-6 .
