CEPL Manufacturing Plant at Jalgaon

Chhabi's intelligent high-frequency switch mode DC

power system is a highly reliable product with

modular design. It is adjustable to various power

networks with super-wide voltage input range.

Rectifier modules being hot-pluggable are convenient

for online maintenance with the cutting-edge soft

switching technology. These rectifiers features high

efficiency with low EMI. Low difference active load

sharing of rectifiers ensures inter-rectifier imbalance

rate of only 3%. An inbuilt power correction is

provided, along with temperature compensation of

Battery charging voltage. CE and EMC certifications

additionally ensure their reliability and safety.

At CEPL, this range is offered in the basic modules :

110 V -10 / 20 / 40 A

220 V - 20 A / 30 A / 40 A

With a very high efficiency, they respond dynamically

for step loads.

Central Monitor is provided with embedded INTEL

CPU as main processor to realize coordination work

of all equipment of power distribution monitoring,

Rectifier module, Feeder insulation monitoring,

battery monitoring and so on. Advanced battery

management program executes intelligent

management. With embedded multi standard

protocols to communicate with the host, the system

can select parameters to report through host

software. The system is applicable to all level power

plants and high-level power substations

Modular DC Power System

Main Features :

Built In Redundancy

Modular DC power supply systems are having built

in parallel redundant structure to match the power

requirements. By adding one (n+1) or more (n+X)

redundant modules the load power is secured even

case of module failures. In case of module failure

alarm is generated for the operator attention. In non-

modular (standalone)systems the redundancy can

only be achieved by TWO complete systems, each

capable of handling the complete load. With a

modern modular system the same level of

redundancy can be achieved by adding one single

module. This of course dramatically reduces the

initial investment and still offers more flexibility.

Scalability

While designing the power system in the initial stage,

it is always challenge to find the exact power

requirement of the entire connected loads.

Additionally, the future power requirement is also to

be taken in to account with the possible additional

loads. Standalone charger systems can only be

Introduction

purchased with a given maximum rating. For future

expansion beyond this, the options are either a

completely new larger system or a new complete

system connected in parallel. Both these options are

not attractive considering the investment and space

restrictions. For modular DC Power systems on the

other hand, one can easily prepare for future

expansion by including pre-wired empty slots for

additional modules. Typically this will already be

included or can be achieved at a very little additional

cost. Being faced with an increasing demand for

more power during the operation or with the

necessity to connect additional consumers to the

system, the customer only needs to purchase the

required modules and integrate them into the

existing system. So, the performance of the system

grows in line with the needs and requirements of the

user. System, output power and, consequently, the

investments are "scalable".

Modularity

Standalone charger systems are available

completely mounted in a system cabinet. Generally

there is logistic problem while transporting them

from manufacturing place to the installation site,

especially if the site is having accessibility problems.

Modular DC power systems, however, are supplied

and commissioned with a pre-wired cabinet with very

low weight. The power supply modules are installed

into the provided sub racks after the system being

completely mounted. Thus, the delivery, moving of

the cabinets to the instillation site become as easier.

Especially in order to increase the availability or the

power output performance, additional modules can

be equipped without special expertise later on.

� Save 48 Nos work loss without affecting power

failure

� Hot Swappable The rectifier is designed to be plug-and-play. There will be no

arcing and the terminals will not be damaged when

inserting / removing the rectifier from a live DC power system.

� Active Load Sharing The rectifier uses advanced digital active load sharing

technology that maintains balancing to within ±3 %.

� Adjustable Output Voltage The output voltage can be set through the front-end

embedded controller. The accuracy is ±0.5 V & 0.2A

� Input Over / Under The rectifier will shut down and its protection indicator (yellow)

Voltage Protection will light up when the input voltage is lower or higher than

preset Voltage

� Output Over Voltage Protection The rectifier will shut down when its output voltage is higher

(HVSD)than HVSD set point.

The rectifier also has two additional software settings that can

be configured using the controller :

1) Manual restart, and

2) Automatic restart attempt within

5 seconds of a HVSD condition.

� High Temperature Protection The rectifier will limit its power of the rated output capacity

when internal temperature becomes higher.

� Over Current Protection The output current can not increase infinity. If over loaded the

output voltage decreases automatically to protect the power

component. The over current protection can be resumed

automatically.

� Fan Fault Protection When the heat sink temperature is goes beyond 85 degree C

the charger module gets shutdown to protect itself.

� Unbalance of Rectifier When the output current of the rectifiers in a DC power system is

Output Current unbalanced, the rectifier whose output current is unbalanced will

be identified automatically and its protection indicator (yellow)

will light up.
