What is a Custom power supply?

A custom power supply is a power device specifically designed and manufactured to meet the unique requirements of a particular application or system. Unlike off-the-shelf power supplies, custom solutions are optimized based on the customer’s specifications regarding output voltage, current, form factor, safety, or environmental conditions. They are commonly used in fields such as medical equipment, aerospace, industrial machinery, and telecommunications, where reliability and precision are crucial. Custom power supplies are generally categorized into two types: full-custom and semi-custom. Full-custom supplies are designed from scratch to meet exact requirements and offer maximum optimization, but typically require more development time and cost. Semi-custom solutions are based on standard models with some modifications, offering faster development and lower cost.

By using a custom power supply, manufacturers can optimize system performance, reduce space, improve thermal management, address EMI/EMC issues, and ensure a long-term stable supply. These benefits are especially important in mission-critical applications where standard power supplies may not suffice.
