Highlights High efficiency and energy saving The efficiency of rectifier ZXD3000 can reach up to 96%. ZTE DC power system is complete with breathing power management function, the rectifier modules sleep by turn in order to save energy and improve system efficiency, the hibernation power loss lower than 4W.
Wide range of AC input voltage ZTE DC power product has a very wide range of AC input voltage from 80V to 300V; the system can work well in the regions with bad or unreliable grid.
Intelligence ZTE DC power provides various types of interface like RJ45, RS232, and RS485 to rrealize ealize remote monitoring. The RJ45 interface easily enables a DC power system to be a member in the network, realizing real-time remote information, sending of alarms and logs, remote modification of working parameters and remote software upgrade, and thus to save maintenance time and cost.
Easy Touch —Fast Query By pressing the query button on a rectifier panel, you can query the running information and alarm information of this rectifier in the monitoring unit. You can also enter the parameter setting menu of this rectifier to set running parameters. This helps maintenance personnel maintain the rectifier and quickly locate faults.
ZTE Solution for Bali Tower Proposed offering from ZTE： -ZXDU68 B151 Rectifier Subrack(19”2U), contains:
3Rectifier Position, 2*3kW rectifier modules configured
Controller: CSU 501B01
AC distribution: 1*40A/2P (L/N/PE, 220V rated, no AC SP D, no AC output )
Battery input: 3*50A/1P MCBs
DC output distribution, the default MCB can be upgrade , the maximum can be reach to 30A : LVD1: 2*25A/1P MCBs LVD2: 2*25A/1P MCBs LVD3: 2*25A/1P MCBs Remark:
we also also can provide one chanel for big load, and MCB can can be 50A or32A.
SIU（Signal Interface Unit ）: 8*DI,8*DO
Typical Installation The rectifier subrack can be installed horizontally or vertically in the 19 ” standard cabinet, the typical installation is as shown in below pictures. And the cable terminal. DI and DO can be hanged some place where it is easy to install, and the installation dimension of cable terminal is 1U *4U.

Technical Clarification For pole sites, Bali Tower requires some additional monitoring functions; we will propose our solution based on our understanding. REQUIREMENTS: a. Classify the tenant by 3 level. This level will related with backup time provided to each tenant, when power disturbanc happening. b. Stated condition at point A is able to be “manually override ” when the tenant agree to add backup time with addtional charge cost. c.
Remotely ON/OFF lighting by certain period of time(6AM-6PM).
d. Health status of the lamp(Broken/Normal) e. Door Access Management.Each engineer need to request for access to Command Center/NOC. After granted, then the engineer will be able to proceed with manually open the cabinet. If there no access from Command Center, alarm notification and siren will be t riggered.
f.
Fan Control
g. Battery Temperature h. Cabinet Temperature SOLUTION PROPOSAL FROM ZTE: a.
Classify the tenant by 3 level. This level will related with backup time provided to each tenant, when power disturbanc happening. ZTE proposal: The tenant can be classified into 3 levels by LLVD1, LLVD2 and BLVD; LVD can be controlled
by backup time or battery voltage. LLVD means Load Low Voltage Disconnection BLVD means Battery Low Voltage Disconnection D isconnection b. Stated condition at point A is able to be “manually override” when the tenant agree to add backup time with addtional charge cost. ZTE proposal: The backup time of tenant can be changed by modifying the level of LVD.
c.
Remotely ON/OFF lighting by certain period of t ime(6AM-6PM). ZTE proposal: An
internal timer in monitor unit (CSU) and 1 DO can be used to controll the switch of lighting,
but we suggest Bali Tower to add a separate external timer to control ON/OFF of lighting. d. Health status of the lamp(Broken/Normal) ZTE proposal: ZTE rectifier system can receive DI from lamp to detect the health status, for example, the
lamp is normal when DI is closed, broken when DI is open, it depends on the specification of lamp itself. e. Door Access Management.Each engineer need to request for access to Command Center/NOC. After granted, then the engineer will be able to proceed with manually open the cabinet. If there no access from Command Center, alarm notification and siren will be triggered. ZTE proposal: When access is approved by Command Center, the CSU in rectifier system will send out 1
DO to unlock the door, and judge whether the door is opened by via 1 DI signal; If the the door is openned without approval from Command Center, another DO will be sent out to trigger alarm notification and siren. f.
Fan Control ZTE proposal: It depends on the specification of fan, normally a separate fan controller should be
provided by cabinet supplier, not by rectifier supplier g.
Battery Temperature ZTE proposal: ZTE rectifier solution can support battery temperature detection.
h. Cabinet Temperature ZTE proposal: ZTE rectifier solution can support cabinet temperature detection.
