R48-1800 and R48-1800A communication power module function and size is exactly the same, the two can replace each other

The main technical parameters of R48-1800 communication power module: weight = 2kg, size 87.9 (H) * 85.3 (W) * 272 (D), the input voltage 80-300Vac; input voltage frequency

The rate of 45-65HZ; the input power factor is not less than 0.99; the output voltage of -42 to -58Vdc; 0-30A output current; rated output efficiency higher than 91%; the maximum output power of 1740W

Mainly used in the following communication power supply system: PS48120/1800 switching power supply system (suitable for access, transmission, railway station, wireless base station and other communication network)

The module has 4 standards; the DC converter is optional, and it can provide 6V, 12V, 24V direct current;
PS48120-3/1800 wall mounted power supply system (for 3G indoor coverage base station; GSM, CDMA mobile base station; railway small base station; transmission relay station, microwave),

Satellite communication station; module standard 4; monitoring 1; battery external);
PS48300/1800 communication power supply system (module can be equipped with 2-10, battery external);
NetSure501 large capacity embedded power supply system (monitor M500D one, module R48-1800 five).

Main functions and characteristics of R48-1800A high frequency switching power supply module
1. hot plug: rectifier module using lossless thermal plug technology, its input and output has a soft start unit, when the module is inserted into the system, will not cause the output of the system

Disturbance of voltage. Replacement module time is less than 1 minutes.
2. digital flow: rectifier module adopts advanced digital flow technology, without monitoring module, module can automatically flow, flow imbalance of less than 1.5A

3. input limit power control: rectifier module according to the input voltage and output voltage changes, the use of advanced limit power control method. The conversion point is in 176V. When the input

When the input voltage is between 176Vac and 290Vac, the module can output the maximum power; when the input voltage is between 85Vac and 176Vac, the input voltage is guaranteed when the input voltage is low

The maximum load demand can ensure the reliable operation of the module, and the relationship between the output power and the input voltage is shown in figure 2-7. Note: when 176Vac, the module is maximum

The output power is 100% rated power, that is, 2900W; when 120Vac, the module maximum output power is 50% rated power, that is, 1450W; 85Vac, module

The maximum output power is 18.75% rated power, i.e. 544W.
