The DEWEN DMR™ Series is a flexible family of modular DC power systems. In addition, it combines high-efficiency rectifiers and smart control for consistent reliability.
Built on British engineering standards, DMR™ systems combine high-efficiency rectifier modules, intelligent control, and advanced protection to ensure uninterrupted power for telecom, energy, transportation, industrial, and infrastructure environments.
One modular platform — multiple configurations, infinite reliability.
Designed for Versatility
The DMR™ platform offers a modular and redundant architecture, allowing systems to be scaled from a single compact module to complex multi-bay installations.
Users can uses the modules to operate independently or within integrated DC plants, providing power ranges from a few kilowatts to hundreds of kilowatts.
Key Capabilities
- Modular, hot-swappable rectifier design
- N+1 or N+N redundancy options
- Input range: 90–305 VAC with active PFC
- Output voltage configurations from 24 V to 220 V DC
- Efficiency up to 96 %
- Intelligent digital controller with local and remote interfaces
- Optional IP54/IP65 enclosures for outdoor or harsh environments
Smart Power Management
DMR™ systems incorporate advanced digital supervision that continuously monitors voltage, current, temperature, and alarms.
Built-in communication options such as RS485, Modbus, SNMP, or CAN enable seamless integration with SCADA, BMS, or network management systems.
Real-time insight. Remote control. Maximum uptime.
Scalable Configurations
| Type | Description | Example Use |
|---|---|---|
| Rack-mounted modules | Compact, high-efficiency rectifiers for telecom and IT cabinets | Telecom, datacom, automation |
| Cabinet systems | Fully integrated DC plants with distribution and monitoring | Infrastructure, utilities, transport |
| Outdoor enclosures | Rugged IP54/IP65-rated systems for harsh environments | Energy, water, industrial sites |
Each system is tailored to customer-specific requirements — including voltage, current, distribution layout, and monitoring interface.
Built to International Standards
DMR™ systems comply with a wide range of international standards. Furthermore, each solution can be tailored to meet regional or industry-specific regulations. This ensures full compatibility with safety, EMC, and environmental directives.
