SolaHD SDU DC-B Industrial UPS Boosts Uptime with Advanced 24 Vdc Protection and Intelligent Self-Monitoring

­The SolaHD™ SDU DC-B Series DIN Rail UPS from Emerson is an advanced 24 Vdc uninterruptible power system engineered to set new benchmarks in industrial power protection. Combining robust design architecture and versatile installation options, the SDU DC-B delivers unprecedented reliability for critical connected loads across the industrial landscape. Compact and DIN-rail mountable, the UPS emphasize space efficiency and seamless integration into existing setups without requiring a separate cabinet.

Intelligent Microprocessor Control

The SDU DC-B UPS features powerful microprocessor-controlled operation that provides comprehensive protection against power interruptions, ensuring continuous operation of mission-critical systems. With a flexible input voltage range of 22.1 Vdc to 28.6 Vdc, the DC-B UPS represents the optimal power backup solution for environments where downtime is not an option.

Advanced Self-Diagnostics and Monitoring

Built-in automatic self-test functionality continuously verifies UPS operation and battery management status, enabling proactive maintenance strategies that maximize system availability. Universal dry contact relay terminals provide seamless remote signaling integration, allowing operators to monitor UPS status from central control systems and respond immediately to any condition changes.

Fanless Design Optimized for Harsh Environments

The SDU DC-B's fanless architecture eliminates internal cooling requirements, reducing noise, preventing dust ingestion, and enhancing long-term reliability in demanding settings. This zero-maintenance cooling approach significantly extends operational life while minimizing total cost of ownership. Robust protection makes the SDU DC-B Series ideal for diverse applications ranging from computer-based control systems and conveying equipment to material handling systems, packaging machinery, and DeviceNet™ networks.

Modular Design, Maximum Protection

Built on a modular, ruggedized platform, the SDU DC-B Series incorporates advanced overload protection in both normal and battery modes. It features an optional UPS power module and battery module (sold separately), providing flexible configuration options that adapt to specific requirements. 

The SDU DC-B's operational temperature range of -15° to +50° C and flexible installation options ensure reliable performance in the harshest industrial conditions, from temperature-extreme manufacturing floors to space-constrained control cabinets.
