Standard Features
Design : Our Sales/Design Engineers are available to work with you
to meet all of your product requirements. All components are designed to
provide 100% continuous full load operation.
Electronics : Our precision Electronics are designed and
manufactured to provide proven stable operation with
± 5.0% voltage/current regulation throughout the
nominal range from 10%-100% of DC output.
Transformer
Winding Material : Splice free, electrolytically pure copper
Core Material : Low Loss, High quality, Grain Oriented Silicon Steel
provides good flux and low eddy current losses
Insulation Material : 'A' Class Insulation is used for ONAN systems.
Process : The coils are vacuum impregnated by Varnish and then
baked to cure. Varnishing provides additional electromechanical Strength.
All coils are wound for stress distribution under fault conditions to
provide superior mechanical strength.
Cooling : 'Reliable' supplies are designed for optimum low
loss/efficient operation and employ specially designed natural oil cooling
to remove the heat generated during operation.
Controls : The following are examples of
typically required Control configurations. 'Reliable'is
committed to working with each Customer on an individual basis to ensure
your Control requirements are satisfied.
- Standard Control (D. C. Metering, Push Buttons and Indicator lights
in a panel on the machine)
- Manual - Remote
- Centralized control Panel for Number of Systems
- Constant Voltage Controller /constant current controller
- Zero Run Down System
- Ampere Hour Meter/Ampere Minute Meter
Semiconductors : 'Reliable' selects its
semiconductors with an appropriate 200% safety factor to provide the
ultimate in reliability. This design criterion limits the junction
temperature of semiconductor to typically less than 800 C , thus
enhancing the life of the equipment.
MS Shell : The enclosure i.e. mild steel steels are fabricated with
8/10/12 SWG HR sheets. The requisite supports along with seam welded cooling
fins are provided to dissipate the heat produced. The housing is checked for
leakage with pressure testing. The job is then paint finished inside and
outside by degreasing and acid resistant Epoxy Paint. Standard Paint will be
BS Grey. Change of shade on request.
Ripple : Standard 6 pulse DC Rectifier will contain less than
5% RMS AC Ripple when operated at Rated Voltage and Current.
Training : Reliable’s service Engineer may instruct our
customer’s operator and Maintenance personnel during the commissioning
/start of the unit or during final test at our works. This can be
operational training and / or full Maintenance repair training.
Spare Parts : 'Reliable' maintains a considerable spare
parts inventory and has the appropriate factory approved spare parts on hand
and ready for your use to assure maximum uptime of your process. Reliable’s
power supplies are designed for decades of trouble free performance when the
installation and maintenance guidelines contained in the service manual are
followed.
D.C. BUS BAR : 'Reliable' uses Electrolytically pure
Copper/ Aluminium bus bar exclusively in our rectifier systems. Bus Block
with bolted joints and flexible connections are designed to minimize bus
losses and to match the client’s application requirement. The laminated
bus structure designed maintain a low bus impedance and low voltage over
shoot.
Quality Control
Each piece of equipment we build is rigorously tested and put through a
systematic quality control examination prior to dispatch. Our test facility
utilize state of art equipment to verify that the Power Supply you receive
is exactly what you ordered. Our staff of highly competent test technicians
performs a full range of operational and functional testing and maintains
complete documentation of all test procedures and results. Prior to
dispatch/ shipment a final quality control inspection is performed.
