Reliable and efficient power supply systems are indispensable for successful military operations. There is an ever-increasing demand for specialized electrical power supply solutions for defense applications. These days, some of the leading designers and manufacturers of critical power supply solutions make power supply systems for harsh and rugged environments. These are known as rugged power supply solutions.
The rugged power supplies are designed for harsh environments with high reliability, power density, EMI compliance, and compact size. The best power supply companies offer customized rugged power supplies, ranging from light customization up to fully customized products.
About the rugged power supply solutions
The rugged power supply solutions are high-tech power electronic products produced for high protection. They are water-proof, and mechanically robust for withstanding harsh conditions in remote areas or under the open sky. These products comply with national and international defense standards such as MIL-STD. Besides meeting thermal and EMI standards, these systems are designed in a unique way to withstand mechanical impact, humidity, and corrosion effects.
Some features of Rugged power supply systems
High power density: These power supplies have high power density, and hence they can produce large amounts of density based on their mass.
Switch mode- low noise: The power supply systems manufactured by the best companies employ design techniques that provide Electromagnetic Compatibility by minimizing Electromagnetic Inference. The rugged power supply systems are generally switching-mode power supplies, and in them, the DC voltage is converted to a chopped or pulsed waveform. This ensures that the power supply makes low-band noise at the fundamentals of the switching frequency and its associated harmonics. To lower the noise, the manufacturers generally minimize radiated and conducted emissions.
Regulatory standards: These power supply solutions are designed in compliance with national and international standards, which are usually required by individual nations. These standards enhance the product’s EMC performance with respect to EMI. Some standard measures are as mentioned below:
Electromagnetic disturbance characteristics include the limits and the methods of measurements.
Have specific features for radio disturbance and also immunity measurement apparatus and methods.
Overcurrent and short circuit protection: If the output current is greater than the specified current, it can damage the power supply to a specific limit. The Short circuit between the power supply output and ground can create the currents within the system controlled by the maximum current capability. The rugged power supply manufacturers make their power supply solutions with proper overcurrent protection. Without that, the high current can cause overheating and damage the power supply and its interconnects.
Over-voltage protection: When the output voltage goes above the specified DC value, it can impose excessive DC voltage, damaging the load circuits. Typically, the electronic system loads can withstand up to 20% overvoltage without doing any permanent damage. The rugged power supply solutions include overvoltage protection that turns the supply off if the output voltage exceeds a specific amount.
Remote error sensing: For compensating the resistive drop of the power path, remote sensing is used in these power supply systems. Remote error sensing is more beneficial for low-voltage, high-current applications.
Choose the best power supply manufacturers
From the pointers mentioned above, it must be pretty clear to understand that the rugged power supply systems are some of the pieces of equipment designed following the latest technologies and innovations. But to get the best power supply solution, make sure to choose a leading manufacturer, as they will provide you with the following benefits:
Quality policy: The best power supply manufacturers place their customer’s satisfaction at the top list of their priorities. They are committed to manufacture and supply products that meet all the requirements of their clients and the requirements of law.
Warranty: The best power supply manufacturers warrant that all their products will be the same as described in any specification and drawing provided by them. Besides, they also offer high-quality products which remain free from defects under normal use and documented maintenance from a period of one year from the date of shipping.
Besides, the leading manufacturers provide strong technical support throughout the life cycle of the products and through the various design stages.
