HindlePower SCR Stationary Float Battery Charger

HindlePower SCR Series ChargerHindlePower SCR/SCRF 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 SCR/SCRF Series is ideally suited to utility, communications and other stationary charger applications.

Features and Benefits

  • Component Selection – Electronic and electrical components are substantially derated to assure long life and reliability. Typical MTBF is 100,000 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.

Environmental Specifications

  • Operating Ambient Temperature – 32°F to 122°F (0°C to 50°C) without derating
  • Storage Temperature –  -40°F to 185°F (-40°C to 85°C)
  • Operating Altitude -3300 feet (1000 meters) above sea level without derating
  • Relative Humidity – 5% to 95% (without condensation)
  • Audible Noise – Less than 65dBA at any point 5 feet from any vertical surface of enclosure. Typical values measure 55 to 60 dBA at 100% load.
  • Ventilation – Units rated 300Adc output or less are convection cooled via NEMA-1 vent openings in cabinet. Units rated 400Adc output or greater have fan-assisted convection cooling with overheat-audible alarm and remote alarm contacts. (Automatic charger shutdown due to overheat is optional.)
