MIL-STD-1275E Power Supplies
Power supplies designed to meet the MIL-STD-1275E standard requirements are typically used in military ground vehicle power applications. They can also be useful to civilian manufacturers of off-road vehicles and heavy equipment who require high reliability in their products.
- Transient spikes of up to ±250 V for 50 µs with durations no longer than 1 ms with maximum energy of 15 mJ
- Surges of 100V surge for 50 msec without degradation and continue to provide a regulated output
- Provide a regulated output down with a minimum of 20 volts input
- Provide rated power at 12 volts input for 1 second and at 16 volts input for 30 sec
In addition, ground vehicles are frequently deployed in dusty, humid, or sandy conditions and anticipating these environmental concerns is essential in the design of any power supply. Hardware must also be able to withstand the shock and vibration requirements for travel in rough terrain. Developing reliable power supplies considering these parameters presents various challenges that require precision-engineered solutions.
The SW2511 family of products have been designed and tested to ensure performance and reliability for these stringent requirements. The power supply is either natural convection or conduction cooled. The enclosure is environmentally sealed to prevent dust and moisture from entering. The DC-DC power supply is also efficient up to 96% and operates up to 1000W or 2000W depending on the model. Our products also incorporate EMI filtering and other advanced features that make them ideal for powering communications, engine control, guidance and other sensitive systems. These military-grade COTS power supplies were designed for versatility and ease of customization so we can accommodate an assortment of application specific changes.
