rectifier devices comprise parallel-connected
rectifier modules in which the rectification
of the mains voltage into a controlled and smoothed
DC voltage is effected. In case of a power failure,
the batteries, which are also parallel connected,
ensure an uninterruptible supply to the load.
After mains recovery, the batteries will be

control and monitoring modules, AC distribution
for rectifier input, DC distribution, batteries,
and low voltage disconnect options.
means of up-to-date monitoring modules, the
processing of all monitoring and control functions
is microprocessor-controlled, and corresponding
LCD displays indicate the system status.
has been providing rectifier systems and services
to the needs of the customers in Telecom, IT
and Oil/gas sector. These systems are custom
made to the load requirements of the customer
with backup. These systems are most suited for
the application, where reliable and clean source
of power is the basic requirement. OSS has experience
in design, installation and commissioning of
these systems for various clients in Telecom
and Oil/gas Sector.
is the representative for Eltek Valere products,
in Oman. Eltek Valere offers rectifiers having
output power ranging from 60 W up to 4,000 W.
All are plug-in units intended for parallel
operation in a DC power system. All of Eltek
systems use state of the art "hot plug-in"
switchmode rectifiers for easily upgradable
system power capability. Multiple rectifiers
operate in parallel to ensure redundant operation.
has number of installations of these systems
at Petroleum Development Oman, Oman Telecommunications,
Ministry of Civil Aviation etc.
