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
