Read MoreThe ARIS Power DCU150M1224 is a compact, all-in-one DIN-rail mounted DC uninterruptible power supply systems delivering 150W of continuous output power. Designed for critical DC loads in industrial automation, water utilities, telecommunications, and electronic security applications, these DC-UPS units combine a high-efficiency AC/DC power supply, intelligent battery charger, and integrated backup functionality.
Output voltage is selectable via DIP switch for either 12Vdc or 24Vdc operation, with configurable buffer times and adjustable charge current to match application needs. Advanced battery management is delivered via the onboard BATTSAFE firmware, which supports a range of battery chemistries including Lead Acid, Ni-Cd and Lithium (Li-Ion, Li-PoFe). The ‘S’ variant (DCU150M1224S) includes support for Modbus RTU communication via dual RJ45 connectors, allowing for optional remote status and fault monitoring.

Features
- Integrated all-in-one solution: Combines high-efficiency AC/DC power supply, battery charger, backup controller, battery diagnostics, and status signalling in a single DIN-rail enclosure, simplifying installation and reducing panel space requirements
- Selectable DC output voltage: Supports either 12Vdc or 24Vdc operation, easily set via DIP switch; output is stabilised during power supply mode and tracks battery voltage during backup operation
- High peak current capability: Delivers up to 25A for short durations (5 seconds), allowing reliable backup of loads with high inrush or transient current requirements such as relays, solenoids, and PLCs
- Advanced battery charging and diagnostics: BATTSAFE firmware implements configurable IUoU charging profiles with recovery mode, battery life test, temperature compensation, and fault diagnostics for Lead Acid, NiCd, and Lithium chemistries
- Flexible system configuration: Adjustable buffer time, charge current limit, and fast charge enablement allow users to tailor system behaviour for application-specific load and battery parameters
- Communication and Remote Alarms: supports Modbus-RTU via dual RJ45 ports for PLC/HMI integration (DCU150M1224S Only), alongside three voltage-free relay outputs for mains loss, battery fault, and rectifier failure signalling
