RS3/RSF Series Semiconductor Fuses

The RS3/RSF Series is a next generation High-Speed Fuse for the protection of power semiconductor devices and is designed in the Traditional Round Body Bolted Style package. RS3/RSF Series High-Speed Fuses rated at 750 Vdc are extremely current limiting and are used to protect power converters, drives and control circuit applications. Designed with lower I2t performance characteristics, these fuses provide balanced performance to extend longevity while lowering potentially damaging heat energy to the devices being protected. In addition RS3/RSF Series fuses have been designed with a universal mounting option to meet customer requirements for installation into a variety of application configurations YINGLANG products offer optimized circuit protection at the extremely fast speed required to protect modern day, sensitive, high-power semiconductor devices.

Designed to protect today’s equipment and systems, YINGLANG semiconductor fuses are manufactured with YINGLANG-developed technology that sets tomorrow’s standards for accuracy, consistent quality, reliability, and predictable performance. By using advanced metallurgical, polymer, and materials research; mathematical modeling, and computerized statistical analysis; YINGLANG engineers have redefined “State-of-the-Art.”

Applications

Designed specifically for supplementary protection of semiconducting devices such as silicon controlled rectifiers (SCR’s), diodes, thyristors, triacs, transistors, and similar solid-state devices. These devices are used in power equipment including variable speed drives, power rectifiers, UPS systems, DC power supplies, and in a wide range of electronic equipment. May be used wherever extremely fast-acting, current-limiting fuses with no time delay are required.

Safety

200,000 A.I.R. — Reliable interruption of all overcurrents up to 200,000 amperes . . . meets present and future system requirements. (Note: L15S series has 100,000 A.I.R.)

•     Extremely Current Limiting — Low I2t and peak let-through currents meet most semiconductor requirements.UL Recognized — YINGLANG semiconductor fuses are recognized under the components program of Underwriters Laboratories, Inc., and carry the mark. UL Recognized semiconductor fuses may be used to provide supplementary protection in UL listed equipment.

Safety

•     Low Watt Losses — Means less heating and power consumption in circuit.

•     Controlled Transient Overvoltages — All circuits are subject to transient overvoltages during fault current interruption. These transient overvoltages (arc voltages) start when fuse links melt or Circuit Breaker contacts part, and subside when circuit is interrupted. Semiconductors are very sensitive to overvoltages. YINGLANG semiconductor fuse designs keep transient overvoltages to low levels and help reduce semiconductor failure.
