AC Power Distribution
AC PDUs
Recommended for new builds
Spectrum Control Inc. is introducing a new best-in-class AC Power Distribution Unit (PDU) product line designed specifically for highly reliable operation in harsh environments. 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.
The platform approach facilitates minor hardware customizations such as input and output connectors and cables, and flexible configuration and operation via software interface.
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 voltage spikes 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.
- For aerospace, defense and industrial customers who need 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.
- Reliability and performance are demonstrated by our MIL-STD-810H and MIL-STD-461G qualification testing.
Features

4 Modes of control for each channel based on external sensor.
- Turn ON if the temperature increases above a set threshold (cooling)
- Turn ON if the temperature decreases below a set threshold (heating)
- Turn ON if the temperature is within an upper and lower test point (Safe Operating Range), or
- Turn ON if the temperature is outside an upper and lower test point (Alarm Mode)
