DIN Rail DC UPS: 12V, 24V and 48V DC
Powers Loads and Charges Back-Up Battery, Ideal for Security, Wisp, and Wireless System
Transmitter/Enclosure 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 prevents total battery discharge
- Operates from street light voltage – 277V AC
- 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
Input: All models 115/230/277 (305) VAC Input

Protection
- Low Voltage disconnect at 1.5 volts per cell
- Internal fuse
- Current limiting
- Short circuit
- Reverse polarity
- Thermal overload shut down and recovery
- IP 20
- Designed to UL 1950
Terminal Blocks
Screw type
Mounting
DIN Rail Bracket (35mm)
Optional
- Battery temperature sensor: 100 feet or 3 foot cable lengths
- Parallel Connection for Redundancy: DIN-UPS units can be paralleled for 1+1 redundancy to obtain a higher system availability. Redundant systems require a certain amount of extra power to support the load in case one DIN-UPS unit fails. The simplest way is to put two DIN-UPS in parallel.
BDA/DAS DIN Rail DC UPS Available
A BDA/DAS version with NFPA compliant alarm signals and battery back-up is available
