We have retained much of our legacy design including the same ratings, footprint and simple user interface, and have added several new and advanced high value features:

  • Full Electronic Protections
  • 3 LED’s for battery state of charge
  • Maximum charge limiting for sensitive loads
  • 4 stage battery charging
  • Dead battery recovery
  • Cover to protect wire terminals
  • Self-diagnostics to detect critical faults
  • Multi-color status LED
  • Telecom mode for sensitive loads
  • Extremely High Reliability
    • Failure rate of less than 1 per 1,000 shipped (<0.1%)
    • 100% solid state. Power MOSFET design
    • Manufactured in an ISO 9000 factory
    • 100% pre-shipment functional testing
  • Longer Battery Life
    • Advanced PWM charging
    • Series design (not shunt) for cool operation
    • 4-stage charging: bulk, absorption, float, equalize
    • Optimized sealed or flooded battery set points
    • Temperature compensated charging
    • Low voltage load disconnect on several versions
  • Designed for Harsh Environments
    • Temperature rating of –40°C to +60°C
    • Epoxy encapsulation for protection against humidity and dust ingress
    • Corrosion protection: marine rated terminals and anodized aluminum case
    • Certified for use in hazardous location
  • Easy to Install and Use
    • Factory pre-sets result in no required install settings
    • Electronic protections prevent damage from wiring mistakes
