DC Power Distribution
DC PDUs
Recommended for new builds
Introducing a new best-in-class DC Power Distribution Unit (PDU) product line. High performance, a full feature set, and a ruggedized design combined with a focus on manufacturability and component availability deliver excellent value to our customers. Additionally, the product series was was designed to facilitate minor hardware customizations such as input and output connectors and cables and flexible configuration and operation via software.
This product line is purpose-designed and built for aerospace, defense, and industrial customers who need to manage and protect high-value assets in harsh environments.
Why Good Power Management Matters
Application Example: Battlefield Command
Modern battlefields are a high value mix of personnel, equipment and systems. Providing reliable power to support equipment and systems, and protecting those valuable peripherals from severe transients or other damaging conditions is an essential part of battlefield strategy.
Reliable power distribution and control means supporting both local decisions and remote control and management. And unlike other industrial or commercial PDUs, power distribution for the battlefield must operate reliably in a wide range of hostile conditions, protecting the needs of the mission.
Product Overview
- For aerospace, defense, industrial and scientific applications where it is essential to manage and protect high value assets in harsh environments.
- Spectrum Control’s best in class AC & DC Power Distribution Units provide secure control and reliable protection unlike most COTS vendors who trade off reliability & ruggedness for cost.
- We do this by building a ruggedized product with a full-featured modern controller supporting the latest security and interfaces combined with current, voltage and temperature monitoring on a per port basis.
- Designed to meet MIL-STD-810H Methods: 501.7 Procedure II, 507.6 Procedure II, 514.18 Procedure I, 516.8 Procedure IV and Ve, and MIL_STD_461G: CS101 | RE102.
