The RSS-1512/P-R is a DC-DC converter that provides reliable and efficient equipment with an adjustable constant current output. The device incorporates advanced, high-efficiency power transistor technology and a maximum power switch that utilizes synchronous rectification to provide enhanced power conversion efficiency. It is a reliable alternative to battery operation, with an input range of up to 61 VDC, and can deliver up to 12 VDC at 15 A, making it suitable for a variety of applications.

Working Principle

The RSS-1512/P-R utilizes two switching step-down converters - a low side buck converter and a high-side boost converter - to regulate output voltage accurately. The low side buck converter utilizes a series of power transistors configured as a buck converter to draw high current from the input voltage and feed it to a low-side DC-DC converter. The low-side DC-DC converter then regulates the output current according to the output voltage demand.The high-side boost converter is responsible for regulating the output voltage of the system by controlling the duty cycle of the high-side switch. This switch is driven with a constant current source in order to minimize load fluctuations and provide stable output current.The output voltage of the system is regulated accurately by the RSS-1512/P-R\'s multi-level power control scheme, which consists of a voltage feedback loop, a constant current loop, and a load regulation loop. The output voltage is compensated with the output current in order to provide precise and reliable power conversion.

Applications

The RSS-1512/P-R is designed for use in a variety of applications, such as telecommunications, industrial automation, medical equipment, LED lighting, railway locomotives, and battery charging. Its wide input voltage range and output current capability make it suitable for high current applications.
