Smart Control & Monitoring

All DEWEN DC systems include intelligent microprocessor-based controllers that monitor voltage, current, alarms, and temperature.
Through RS485, Modbus, or Ethernet interfaces, operators can integrate DC systems with SCADA or BMS platforms for real-time data and predictive maintenance.

These systems can also integrate with broader power conversion systems for complex AC/DC applications.


Built to Industry Standards

Our DC power systems are designed and tested in compliance with:

  • IEC 61000 / EN 62040 (Performance & EMC)
  • ETSI EN 300 132-2 (Telecom DC power)
  • BS EN 60529 (IP ratings up to IP65)
  • ISO 9001:2015 (Quality management)

Every system undergoes factory acceptance testing (FAT) and full-load validation before shipment.


Sustainability Through Efficiency

DEWEN DC systems deliver low energy losses, reduced heat dissipation, and optimised component lifespan, supporting sustainable operation throughout the product lifecycle.
Modular systems allow future expansion or replacement without full system overhaul — reducing total cost of ownership and environmental impact.
