DIN Rail DC UPS

Newmar DIN Rail DC UPS, 12V, 24V and 48V DC, 5-35 Amps

DIN Rail DC UPS:
12V, 24V and 48V DC

Powers Loads and Charges Back-Up Battery, Ideal for Wheel House and Engine Room Applications

  • Combines all system power functions: power supply, battery charger, UPS circuitry and status monitoring in ONE compact DIN rail mount unit
  • Dual outputs for load and battery:
    • “Load priority” output distribution ensures power is dedicated first to the load, with remainder then allocated to battery charging, thus preventing a discharged battery from impacting operation of critical loads.
    • 3 step charging for rapid battery recovery, programmable for battery type, with optional temperature compensation sensor
  • Battery automatically supports load anytime AC fails
  • Low voltage disconnect protects battery from total discharge
  • Automatic periodic battery health diagnosis
  • High operating temperature range to 70˚ C
  • Alarm contacts: AC fail, battery at risk
  • Communication MODBUS via RS-485 interface (DIN-UPS 48-10, DIN-UPS 24-20, and DIN-UPS 12-35 models only)
  • CE Approved/Designed to UL 1950
