ZXDU58 W121 V4.0R01M08 For Communications Equipment

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.

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.

Centralized Supervision Unit

The Centralized Supervision Unit (CSU) manages the power distribution unit, rectifiers and batteries of the ZXDU58 W121 system.

Functions
Collects the operational data and monitors the operation of the system.
Provides alarm and necessary protection if the system is operating abnormally.
Sends data to the background Supervision Center (SC) and receives the commands from the SC. In this way, the system can be monitored remotely.

Indicators

The indicators indicate the current operational status of the CSU. For a description of the CSU indicators.

Buttons

The reset button is used to restart the CSU.
Users can perform querying and setting operations through the buttons laid on the front panel of the CSU.
