HR8022-001 48V/2160W/540W Energy System 1-1
1. Introduction 1.1 System Introduction The power system is specially designed for the 48V telecommunication power applications. By incorporating state-of-the-art switched mode rectifier and advanced microprocessor technology, the system is able to perform efficient AC to DC power conversion and at the same time carry out intelligent monitoring and control functions. The CPS is divided into 4 major functional blocks consists of 1. Control and Supervisory Module 6 (CSM6), 2. AC Power Distribution Unit (ACPDU), 3. Rectifier Modules, 4. DC Power Distribution Unit (DCPDU).
The Control and Supervisory Module 6 (CSM6) consists of the CSM6-1 and CSM6-2. The CSM6 is the central supervisory unit, which monitors and controls the operating parameters of the entire system. The CSM6-1 is equipped with LCD panel and soft keypads which serve as a user-friendly interface to monitor or program various system parameters and the CSM6-2 is the Data collector which collects and processes system data before passes to CSM6-1 for display. The CSM6 supports Local and Remote Monitoring & Control functions, for local monitoring & Control, the link between the system and the PC is made through the RS-232. However for the Remote Control and Monitoring, it can be achieved through Public Switch Telephone Network (PSTN) and Ethernet(TCP/IP). The CSM6 also has the battery management function which ensures proper charging of batteries so as to maximize energy storage and to prolong the life of batteries. The AC PDU distributes AC power to the rectifiers and other portions of the system. A single pole MCB (Miniature Circuit Breaker) is available within the AC PDU to isolate the system from the mains. The AC PDU is also installed with an array of Surge Protection Device which protect the

system against line surge. The rectifier modules carry out AC to DC power conversion in the system. Each rectifier is able to deliver a rated output power of 540W at a nominal output voltage of -54V. Therefore, when the system is expanded to its fullest capacity of four rectifiers, it is capable of delivering a maximum power of 2160W to external loads and batteries. The rectifiers are modular in design, hot-swappable and exhibit excellent current share performance when operated in parallel configuration. The system is hence flexibly configurable to meet different power consumption requirements and to achieve N+1 redundancy. Control of rectifiers can be carried out in a centralized manner on the CSM6. In addition, the operating conditions of individual rectifier can also be easily monitored on the CSM6. The DC PDU distributes DC power from the rectifiers to external loads and batteries. Within the DC PDU, there are MCBs protected distribution ways to be connected to external loads. The DC PDU also incorporates two battery connections, which are equipped with two MCBs for protection purposes. The battery connections allow the system to have power backup capability in the event of an AC failure.

2. Overview of the System 2.1 System Architecture The system dimensions is 132.6mm x 482.6mm x 277.0mm (HxWxD). The ACPDU is fed by AC cables which are terminated at the AC input terminal block. The DCPDU distributes DC power from the rectifiers to external distributed load and battery. A positive and a negative busbar carries DC power from the rectifiers to the DCPDU. There are also battery connections within the DCPDU which is equipped with one 100A LVDS for loads control. The LVDS provide protection over discharge of batteries. In the event of an AC failure, energy from the batteries will flow through the DCPDU to the external distributed loads. Hence, the loads will not experience power interruption. The energy system has four pre-wired rectifier compartments. Rectifier installation is swift, straightforward and does not require further connection of cables. Since the rectifier is modular and hot-swappable in design. Different number of rectifiers can be installed onto the system to meet varying power consumption requirements. This allows incremental system expansion to be realized easily. Maintenance work can also conveniently carried out as any rectifier can be removed and replaced without interrupting system operation.

2.8 System Alarm The system is equipped with various fault detection schemes and alarms to keep users informed in the event of fault conditions. The system is also equipped with four voltage free relay contacts (dry contacts) to keep remote users informed when a fault occurs. The relay contacts will respond to normal and fault conditions as indicated in the table below : - Table 2.2
Operating Conditions COM, NO Contacts COM, NC Contacts
Normal condition Open Close
Fault condition Close Open
2.9 System Protection The system is equipped with various protection schemes to ensure no damage occurs in the event of abnormal conditions. Some of the main protection schemes are explained below : -
l Overcurrent protection (OCP) : At the AC input, the system is protected against overcurrent by a MCB. The load MCBs at the DC PDU protect the system against overcurrent drawn by external distributed loads. The battery MCBs prevents overload of the battery bank. Overcurrent limit of rectifiers can be programmed in a centralized manner on the CSM6. Rectifier overload current will not exceed the preset limit.
l Overvoltage protection (OVP) : When the AC input exceeds 308Vac, the rectifiers will cease to operate to prevent component damage caused by overvoltage stress. The rectifiers will resume normal operation upon removal of abnormal condition. Output OVP will be activated when the system output voltage cannot be regulated and exceeds 60V ± 0.5V. Rectifiers at fault will be forced to shutdown. Manual reset is required to restart a rectifier which has been shutdown due to output OVP fault.
l Over temperature protection (OTP) : The system over temperature alarm will be activated when the ambient temperature in the system raises above a preset level. The default preset level is 40°C. In addition, when the rectifier heatsink temperature raises above a default preset level of 80°C, the rectifier fault alarm will be activated. If the heatsink temperature raises further and reaches 90°C, the rectifier will be forced to shutdown. The rectifier will resume normal operation when the heatsink temperature reduces below 70°C.
l Surge protection :
At the AC input, the system is protected against line surge by an array of 20KA/275Vac SPD
module.

2.10 Battery Management The CSM6 carries out battery management functions according to the user preset parameter values. Details on the battery management parameters can be found in the CSM6 User Manual. In the event of an AC failure, the CSM6 will calculate the discharge Ampere-Hour (AH) of the batteries. When AC recovers, the batteries will be recharged automatically in equalize mode according to the preset charging coefficient (CC) or automatic charging time (ACT). One critical aspect of battery management is temperature compensation. The IC LM335 converts the battery temperature sensed into a current signal. The signal is then processed by the CSM6-2. Based on the temperature information obtained, the CSM6 will adjust the output voltage of the rectifiers accordingly. The desired temperature compensation characteristic can be obtained by changing the temperature reference point (TBP), temperature rise rate (TS) and voltage decrease rate (VS) settings. Low Voltage Disconnect (LVD) Protection :
The Load LVDS is to disconnect load, The disconnect and reconnect voltages are preset at 43.0V
and 50V respectively.

el. 5. Important Notices
5.1 General Guidelines The following guidelines must be observed during system installation, system operation or when maintenance work is carried out. 5.1.1 Installation l System installation must only be carried out by qualified personnel. l Ground resistance must meet local requirements. l Any equipment connected to the system must be properly grounded. l The conductors connecting external surge arresters must be as short as possible and the
resistance must be less than 10Ω. If metal tube is used to protect the conductors, both sides of the tube must be properly grounded.
l External surge arresters must be located far from inflammable materials. For safety reasons, surge arresters must be installed in protective case.
l The distance between any metallic part and exposed conductor must meet relevant safety clearance requirements.
5.1.2 System Operation l Before operating the system, it must be ensured that the input voltage, input frequency
and other operating conditions are within the specification. l The rectifier module must only be operated with its pin housing mated with AMP
211149-1 housing. Refer to the rectifier user manual for more details. l When using sealed lead acid batteries, attention must paid to the charge data and
warning notices provided by the battery manufacturer. l If any part of the system is damaged, it must undergo maintenance immediately.
5.1.3 Environmental and Airflow Considerations l Operating the system in dusty environment may result in damage. Excessive dust
settling inside the rectifier may result in poor heat dissipation and degradation of product performance. It is recommended to operate the system in air conditioned environment.
l The system must be operated in properly ventilated environment. Do not impede airflow through the system and rectifier modules by blocking or covering the ventilation holes on the front and back panel of the system.
l Do not operate the system in environment containing inflammable gas or material. l Batteries produce combustible gas. Hence, the room must be properly ventilated.
5.1.4 Maintenance and Repair l Maintenance work must only be carried out by qualified personnel. l During maintenance or repair, do not touch any conducting part in the system while the
system is in operation. l Before carrying out repair work on the rectifiers, wait for at least 5 minutes after switching
off the power to allow the internal capacitors to discharge.
