1-1

SJ-20120703093141-002|2013-01-08 (R1.2) ZTE Proprietary and Confidential

ZXDU68 B201 Product Description

With 50% - 100% output power, the rectifier efficiency is ≥ 96%.

Automatically Switching the Rectifiers to the Sleep Mode

The system switches one or more rectifiers to the sleep mode according to the load power.
The power of a rectifier in sleep mode is not larger than 4 W.

A Wide Range of Input Voltage

A wide range of input phase voltage (90 V to 295 V) makes the system suitable for areas
with unstable power sources.

Capacity Expansion
When fully configured, the system is equipped with four ZXD3000 (V5.0) rectifiers and can
provide a rated output power of 12 kW when the output voltage ranges from -48 V to -57.6
V.

Accessible via Web Browser

The system can be remotely managed through a computer installed with a web browser
anywhere if Ethernet is available.

Managing Data in Batches

Users can set the parameters in batches, copy records and upgrade programs via a USB
flash drive.

Professional Monitoring and Management

l The transmission speed is high via CAN bus.
l Multiple protection functions, such as Load Low Voltage Disconnect (LLVD1), Load
Low Temperature Disconnect (LLTD), Battery Low Voltage Disconnect (BLVD), and
Battery High Temperature Disconnect (BHTD).
l Users can press the QUY button of a rectifier to query the data of the rectifier or control
it.

Flexible Monitoring Networking

The system provides input and output relays, RJ45 Ethernet interface, RS232 interface,
RS485 interface, and USB interface. The system supports multiple monitoring networking
modes via Telnet, Hypertext Transfer Protocol (HTTP), File Transfer Protocol (FTP), and
Simple Network Management Protocol (SNMP).

ZXDU68 B201 Product Description

2.3 Centralized Supervision Unit

The Centralized Supervision Unit (CSU) is the foreground monitoring unit of the ZXDU68
B201 system. It monitors the AC distribution, DC distribution, rectifiers and batteries of the
ZXDU68 B201 system.

Functions
l Delayed trigger alarm waits for technician’s authorization code before informing the
Supervision Center (SC) of access attempt. This function provides potential reduction
of the SC interventions greatly.
When the door with a door sensor is open, all alarms will be on hold and not sent to
output relays in this case, and the correct 4-digit key code (password) must be input
within a certain time (Login Max.Time, one minute, by default). All alarms are sent
to output relays immediately if the correct key code is not input within the time.
l Gives an audible and visual alarm and provides the protection function when the
ZXDU68 B201 system is faulty.
l Collects the operational data and monitors the operations of the ZXDU68 B201
system.
l Performs advanced battery management with protection functions.
l Manages the rectifiers and automatically switches one or more rectifiers to the sleep
mode to save energy.
l Transmits data to the background Supervision Center (SC) and receives commands
from the SC. In this way, the ZXDU68 B201 system can be monitored remotely.
l The CSU can be remotely managed through a computer installed with web browser
anywhere if Ethernet is available.

Appearance
