NEW RANGE
NEW RANGE: PROTECT RCS INDUSTRIAL RECTIFIERS, CHARGERS & DC SYSTEMS
Protect RCS is an evolution of the highly successful
SPR/TPR range from Saft Power Systems which is installed
globally and used for all Industrial applications.
The main advance of the new Protect RCS range is the
introduction of the GCAU card which integrates more
cutting-edge hardware functions.
The Protect RCS rectifiers are thyristor-controlled rectifiers
suitable for charging nickel-cadmium or lead-acid batteries
while supplying DC loads. They can also be used without
batteries as direct power supplies.
This new range of DC Systems is available in three levels:
• The first level consists of the Standard Rectifier
with a compact set of alarms.
• The second level offers a set of Basic Options,
extensive functions and alarms.
• The third level offers a full set of Extended Options,
extensive functions and alarms allowing customization
of the systems to comply with special customer
requirements.
The rectifiers are built as independent modules, optional
equipment like distribution boards, diode droppers etc.
are installed in separate cubicle sections.
Because of the high level of standardisation and
integration, the design reduces the need for extensive
internal wiring.
Cabinets are floor mounted and can be designed
to meet special requirements. The batteries are mounted
on free-standing racks or in cabinets together with
or separated from the rectifier.
"GCAU" Generic Control and Alarm Unit (A1)
The main card is the GCAU (Generic Control and Alarm
Unit). It performs measurements, control and process
control (charge process control) and provides a wide
range of alarm and monitoring options, a user-friendly
control/display interface, and facilities for data logging
and remote communication.
The card has all the necessary controls to pilot single
and three phase thyristor chargers. For three phase
systems a driver card is connected to the GCAU card.
The GCAU card uses a fully digital control algorithm
to ensure the required flexibility.
The GCAU card incorporates two micro controllers, using
the latest micro controller technology to ensure a high
degree of safety.
The tasks of these micro controllers are:
• Process communication and Monitoring
• Regulation and synchronization
Each micro controller has its specific dedicated task.
One micro controller is dedicated to the control
algorithm while the second takes care of alarm,
communication and charge process tasks.
The two micro controllers check each other’s
functionality and will shut down the system
safely if an operating error is detected.
