ZXDU58 W121 V4.0R01M08 ZTE Outdoor DC Power System For Communications Equipment

 

System introduction

 

The ZXDU58 W121 system is an outdoor DC power. It provides -53.5 V DC power for communications equipment.
AC input mode: Three-phase five-wire (L1/L2/L3/N/PE), 220 V - 240 V (phase voltage) / 380 V - 415 V (line voltage), 50 Hz / 60 Hz.
In full configuration, the ZXDU58 W121 system is equipped with four ZXD1500 rectifiers, which form a rated output current of 120 A.
For the ZXDU58 W121 system appearance, see Figure 1-1.

System features

 

The ZXDU58 W121 system has the following features:
*A wide range of input phase voltage (80 VAC - 300 VAC) makes the system suitable for areas with unstable voltage.
*Integrating the power distribution, rectifiers, CSU and batteries in a single cabinet, and thus saving installation space.
*The rectifier is hot-pluggable, and convenient for installation and maintenance.
*Intelligent CSU.
*With heat exchanger and Thermoelectric Cooler (TEC) for heat dissipation.
*High reliability with Mean Time Between Failures (MTBF) ≥ 2.2 × 105 h.
*Multiple networking interfaces: input relays, output relays, RS232 interfaces, and RS485 interface.
