DC Power Systems and DC Power Supplies | Newmar DIN Rail DC Power Systems | DIN Rail DC UPS with Battery Detection System

DIN Rail DC UPS with Battery Detection SystemThe Newmar DIN Rail DC UPS with Battery Detection System, 12V, 24V and 48V DC, powers the load while it charges and monitors the status of the back-up battery. The DIN rail DC UPS meets the NFPA 1221 alarm requirements. It powers bi-directional amplifiers (BDA), charges and monitors back-up battery with AC and DC fail alarm contacts.

DIN Rail DC UPS with Battery Detection System Features

  • Combines all system power functions: power supply, battery charger, UPS circuitry and status monitoring in one compact Din Rail mount unit
  • Alarm outputs comply with NFPA public safety in-building wireless communications back-up power requirements for powering Bi-directional Antennas (BDA): AC Fail, Low Battery, and Charger Fail
  • Separate outputs for load and battery
  • “Load Priority” circuit prevents discharged battery from impacting operation of critical loads when AC power is restored
  • 3 step charging for rapid battery recovery, programmable for battery type, with optional temperature compensation sensor
  • Low voltage disconnect protects battery from total discharge
  • High operating temperature range to 70˚ C
  • Communication MODBUS via RS-485 interface/RJ45 (model BDS-DIN-UPS 48-10 only)
  • CE Approved/Designed to UL 1950
  • Meets NFPA 1221 Requirements for In-Building Public Safety Communication Systems
