Since it was invented in the 19th century, the railway has been one of mankind’s primary means of transportation. In the late 20th century, we witnessed the birth of computers, the internet, and base stations, which are shattering spatial barriers. Moving into the 21st century, drones have further expanded human horizons. As of now, the functionalities and technical applications of these inventions have advanced significantly, along with the power components employed. Among these transformative inventions, Delta's DC-DC converters stand as indispensable components spanning from a few watts to kilowatts to meet diverse requirements in the realms of transportation, networking, and others.
- High Voltage Bus Converters FB7SR and FG5SR Series for Powering Tethered Drones
As drone technology progresses and becomes more accessible, its application scenarios have been diversifying. One noteworthy advancement is tethered drones, which find pivotal roles in disaster relief, particularly during critical moments in remote areas such as typhoons or earthquakes.
Deployed in challenging terrains during relief operations, a single flight mission of tethered drones can span several days, which is unattainable using conventional batteries. The key distinction between tethered and regular drones lies in the former's power cable tethered to the ground via a base station, allowing remote control and high-voltage power transmission through the cable to minimize energy loss. Voltage conversion is crucial to powering the internal components of tethered drones. Designed to address this requirement, Delta's High Voltage Bus Converters FB7SR and FG5SR Series feature input voltages ranging from 200V to 900V, delivering output power up to 1,200W with an impressive efficiency of up to 95%. Moreover, these Series support parallel operation of up to 10 units, collectively reaching a remarkable output power of 10kW.
Beyond disaster assessment, tethered drones can also function as temporary telecom hubs by carrying small base stations on flight missions to establish essential communication links in disaster-stricken regions. These temporary base stations could adopt Delta’s Regulated Bus Converters H48SA Series which offer an input voltage range of 36V to 75V and four output voltage options of 5V, 12V, 28V, and 50V. Among these, the 28V and 50V models offer an output power of up to 1,500W and efficiency up to 97.4%, suitable for base stations situated on high buildings or mountaintops.

- High-Power AC-DC Modules PACSR Series Provides Power Conversion for Small Base Stations
Delta also develops high-power AC-DC brick converters, featuring a versatile input voltage range and enhanced insulation to withstand harsh environments. The PACSR Series, in particular, shines in small base stations mounted on electric poles, delivering 220V or 110V output power. Encased in a robust metal shell for efficient heat dissipation, the PACSR Series has become a key power component to global mainstream telecom equipment.
- Key Player in Power Conversion for Transportation and Industrial Vehicles
Beyond drone and telecom applications, Delta's DC/DC module power converters also find their place in transportation, including railways and non-automotive vehicles. Within the intricacies of railway interiors lie systems consisting of drive control, power control, safety monitoring, and communication systems, all requiring voltage conversion for seamless operations. Delta’s isolated DC/DC converters ensure stable power to prevent drastic voltage fluctuations or power outages that may arise during emergencies such as sudden braking. Among them are the H80SV, HA0SP, Q80SV and QA0SV Series that comply with the EN45545 fire safety standard and EN50155 railway compliance standard, boasting a wide input range of 16.8V to 170V.
In non-automotive vehicles such as golf carts and forklifts, Delta's Box Type Converters, including B83SR, B70SR, B70SP, B40SR and B62SR are indispensable, powering crucial headlights and control circuits. These Series provide input voltages from 18V to 150V, output voltages of 12.4V, 13.7V, and 24V and output power ranging from 110W to 500W. They also come with features such as hot-swapping and meet the IP67 waterproof and dustproof standards, making them operational in harsh environments.
Apart from the above-mentioned applications, Delta's converters are also widely used in industrial equipment, renewable energy facilities, and consumer electronics products such as smart phones and cameras. Delta will continue to develop high-quality and stable power converters to meet the needs of different fields and application scenarios.
