GNB
Industrial Power GSCR Series of industrial float chargers is designed
to automatically control charging rates for a wide variety of battery
types and to simultaneously provide full-rated output
for both continuous and intermittent dc loads.
The chargers are constant voltage devices with automatic current
limiting. Voltage regulation and current limiting are controlled by
solid-state integrated circuitry to assure maximum performance in
minimum space.
The GSCR Series is ideally suited to utility, communications and other stationary charger applications.
DESIGN FEATURES
Component Selection
• Electronic and electrical components are substantially derated to
assure long life and reliability. Typical MTBF is100,000 hours minimum.
Components are selected or designed to provide a system life expectancy
in excess of 30 years.
Modular Construction
• Control circuits, alarm circuits and electrical sub-assemblies are
printed circuit board wired or modularized with plug and socket
connections for easy serviceability.
Standard Sub-assemblies
• Control modules and many electrical sub-assemblies are standardized
across the entire range of charger sizes. This minimizes spare parts
inventory and simplifies maintenance.
Durable
• Front panels are recessed to prevent accidental damage to meters and
controls. Standard cabinets are NEMA-1 enclosures of heavy-gauge
phosphatized steel with an attractive, long-lasting acrylic enamel
finish.
Easy Troubleshooting
• A complete service manual, color-coded wiring, test-point
identification and circuit-symbol labeling of internal components make
troubleshooting easy.
Ease of Adjustment
• Tap adjustments are not required. Output float voltage, equalize
voltage, current limit and alarm levels are potentiometer adjustable.
Ease of Access
• Internal components and connections are easily accessible and/or
removable through a hinged front door that opens approximately 180
degrees for easy serviceability.
Ease of Installation
• Cabinets are floor, wall or rack mountable and equipped with
knockouts for cable or conduit entrance. Input, output and remote alarm
connections are wired to easily accessible, internal terminal blocks.
