Rugged PDUs
Nova Electric
Nova Electric offers a full line of Rugged PDUs (Power Distribution Units) designed to manage power capacity and functionality for harsh environment applications in compliance with MIL-STD-810, MIL-S-901, and MIL-STD-167. Enhanced filtering to meet MIL-STD-461 and Tempest-Grade requirements is available optionally.
Nova’s Rugged PDUs essentially serve as a “circuit breakers” that protect expensive and sensitive loads such as computers, displays, control devices, sensors, and weapons systems against current inrush, spikes, and short circuit conditions. As such, in some cases, PDUs are also referred to as circuit breakers, remote power control (RPC,) and other trade names.
Some applications have a single input available, but require multiple output voltages. Nova Electric offers such Rugged PDUs, most commonly with 120 VAC, single phase input and multiple 120 VAC single phase outputs plus multiple DC outputs (such as 28 VDC, 12 VDC, and 6 VDC) using internal power supplies.

Rugged PDUs
PDU Type
Basic Rugged PDU
Nova’s Basic Rugged PDU combines a single power input, a circuit breaker (or fuse), and multiple power outlets in a single enclosure. While similar in function to an office power strip, Nova Electric’s PDUs are made of high quality materials and components intended for long service and demanding military environments. They’re most often (but not always) built as 19″ rack-mount enclosures to power several electronic devices as part of a total system. Basic units will typically have NEMA, IEC, or MS type connectors, but can also feature a variety of specialized connectors for military and other harsh environments. Any number of signal, connector, indicator, and circuit options can enhance a basic unit’s design.
Switched Rugged PDU
Nova’s Switched Rugged PDUs have the ability to switch individual or groups of outlets on and off to allow for some power management. Switching may be accomplished through controls on the PDU or remotely through dry contacts or network communications. There may also be capability to delay the application of power after a switch is turned on. This allows controlled startup of equipment which may have high surge loads upon power up close to the limit of downstream circuit breakers.
Auto-Switched Rugged PDU
Nova’s Auto-Switched Rugged PDUs are designed to allow a primary and secondary power source to power the entire set of outlets. If the primary source power fails or goes out of tolerance, the secondary source is applied. This is accomplished using high-speed voltage sensing components so that power loss to the outlets is short enough that most equipment will not detect the power drop and remain fully operational during the power transfer. This is typically used for high-availability applications with redundant power systems.
Metered Rugged PDU
Nova’s Metered Rugged PDU incorporates the ability to display real-time current draw in Amps by incorporating either digital or analog indicators. This eliminates the guesswork of estimating whether the PDU has the capacity to connect more devices.
