Starlink provides global internet connectivity through low Earth orbit satellites, and its terminals require stable power supply at 48V. The DC-DC converter is a key adaptor device that can convert inputs such as 12V/24V to 48V output, ensuring the operation of the terminal. This converter has a wide range of applications: in Chilean fisheries, it is used in combination with solar energy to reduce energy consumption and costs; on American railways, wide input converters are used to maintain train networking; ships and off-grid exploration points also rely on it for voltage stabilization.

Summary: MTBF vs. Warranty

In the power supply industry, MTBF and Warranty Period both reflect product longevity but in different ways.

MTBF is a statistical measure, expressed in hours, showing the average time a product runs without failure. It reflects design and component reliability but does not guarantee any single unit’s lifespan.

Warranty is a service commitment, usually 3–5 years, during which the manufacturer covers defects. Its length depends on confidence, cost, and competition.

Key point: MTBF is a reliability forecast, while warranty is a service promise. Together, a high MTBF and solid warranty provide the best mix of engineering quality and customer assurance. Read More

In electronics and electrical engineering, wires may seem small, but they play a vital role in reliability and safety. Among UL-certified cables, UL1185, UL2468, and UL2464 are three of the most common. UL1185 is a shielded wire for stable signal transmission, used in instrumentation and audio/video equipment. UL2468 is a flat, flexible, low-cost wire ideal for power supply lines and LED strips. UL2464 is a multi-conductor control cable that carries both signals and power, widely used in industrial control and computing. Choosing the right wire depends on the application: UL1185 for signals, UL2468 for cost-effective power, and UL2464 for versatile control. Looking ahead, the industry is moving toward eco-friendly, high-performance, and customized cables to balance performance, cost, and compliance. Read More

Switching power supplies, characterized by the use of pulse width modulation (PWM) control ICs and MOSFETs, offer significant advantages over linear power supplies, such as higher efficiency, smaller size, and lighter weight. Despite their complexity and noise generation, switching power supplies are preferred in modern electronic equipment due to their efficient power conversion and versatility in step-up and step-down voltage applications. Linear power supplies, however, remain valuable for their simplicity and low noise in analog circuits and amplifiers. The choice between these power supply types depends on specific application requirements. Read More
