Securing the Backbone of Energy Infrastructure
In power generation and substation environments, uninterrupted and stable DC and AC power is essential for grid stability, plant safety, and critical system protection. DEWEN™ designs and manufactures robust UPS systems, DC power solutions, and industrial converters engineered to meet the demanding conditions of utility-grade applications.
🔋 Industrial UPS for Grid and Plant Protection
DEWEN®’s industrial UPS systems are engineered to protect sensitive substation and generation assets including:
- SCADA systems
- Control circuits
- Protection relays
- Communication and automation panels
With double-conversion topology, hot-swappable modules, and remote monitoring, these systems ensure continuous operation and fast recovery during blackouts, load shifts, or grid fluctuations.
⚙️ DC Power Systems Compliant with IEC 62040-5-3
Our DC UPS and rectifier systems are specifically designed to support:
- Trip/close coil circuits
- Battery banks for control power
- RTUs and telemetry panels
in substations and control rooms.
These systems conform to IEC/BS EN 62040-5-3 — the global standard for DC output UPS performance — and offer:
- Redundant rectifier modules (N+1 architecture)
- Temperature-compensated charging
- Alarm relays for fault and battery events
- Built-in diagnostics for substation integration
Their rugged IP54 enclosures and thyristor or modular topologies ensure stable operation in harsh industrial zones, including thermal plants, offshore grids, and transmission substations.
🔄 Power Conversion Solutions for Critical Utility Loads
DEWEN’s frequency converters and inverters deliver precision control for sites managing:
- Black start conditions
- Variable generation loads
- Control of isolated voltage domains
These solutions offer full compatibility with BMS, SCADA, and utility control protocols, ensuring seamless integration and real-time status communication.
