The 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
