Ground Vehicles


Leader in Ground Vehicle Solutions

DDC, the leader in high reliability data networking, power control and motion control technology for the aerospace and defense industry, has provided field proven integrated circuit and subsystem solutions to serve the performance, reliability, and environmental requirements of military ground vehicles for more than 30 years. The new Joint Light Tactical Vehicle (JLTV) utilizes DDC's SSPCs to enable smart power management and increased reliability.


Ground Vehicles with DDC On-Board

Military ground vehicles including the JLTV, M1A2 Tank, and the Bradley troop transport have evolved into highly technical, highly sophisticated systems. With the abundance of new electronic equipment being added on-board the vehicle, ground vehicle systems now require more power than is available, creating the critical need for load management and load shedding. DDC's Solid State Power Controllers provide the load management and automated switching required to provide the necessary power to support the mission systems being employed by the operator, while protecting the loads, wiring and sub-systems. DDC's motor controller and motion feedback solutions enable precision actuation and control of actuated subsystems including turrets, doors and weapons systems. DDC, the leader in MIL-STD-1553 data bus technology, provides the onboard connectivity solutions linking command and communications data between electrical subsystems.

1,000,000 SSPC nodes installed on military vehicles since 1988!

DDC is the world leader in the design and manufacture of programmable solid-state power controllers (SSPC) for military vehicles, with more than 1,000,000 nodes installed since 1988. In addition to distributing and controlling power with reduced SWaP, while protecting loads and wire harnesses with higher reliability and longer life, DDC SSPCs also enable smart power 
management that simplifies vehicle power control and provides health and diagnostics data that allows the operator to focus on other mission critical activities.

SSPCs replace traditional electromechanical relays and thermal circuit breakers in power distribution systems, offering more accurate trip protection with solid-state reliability, while reducing overall vehicle-level weight.

DDC was the first to offer SSPCs for ground vehicles, UAVs, and non flight critical civil aerospace platforms. Highly reliable, these products are used in the M2 Bradley Fighting Vehicles, M1 Abrams Main Battle Tank, M109A7 Paladin Howitzer, Oshkosh Defence's family of Joint Light Tactical Vehicles (JLTV), and other high performance/severe environment applications.

DDC's SSPCs support real-time digital status reporting and computer control, and are equipped with instant trip, true I²T wire protection, multiple value added options, and supports multiple communications protocols. DDC offers custom SSPC modules that are rated up to 400A, and multi-channel boards that are rated up to 100A per channel. SSPCs offer reduced size and weight compared to electromechanical approaches, while also providing enhanced performance and functionality.
