AC-DC converters are used to convert alternating current (AC) to direct current (DC). The RWS1500B15/RF is an AC-DC converter designed to meet high power and high-reliability requirements. It offers significant power savings over other AC-DC types and provides a cost-effective solution for applications that require reliable performance and low emissions.

The RWS1500B15/RF offers a 120 W power rating with a 15 A output current and a low total harmonic distortion rating of 0.15%. It is designed to operate in either Class A or Class B mode and offers various protection features to protect the system against over-load, over-voltage, and short circuit conditions. It is also designed to be highly efficient and offers an average efficiency of 81% at an operating temperature of 25°C.

The RWS1500B15/RF is a desktop-style converter featuring an open-frame design and a universal AC input voltage of 85-265VAC. It is also equipped with a power good signal indicator, allowing users to easily monitor the system’s status. Additionally, the unit has a high-temperature capability and is designed to minimize audible and electrical noise. It also offers a variety of mounting options for easy installation and configuration.

The power conversion of the RWS1500B15/RF is based on a flyback topology. This topology is widely used for offline power supplies and offers the advantage of being able to operate at a wide input voltage range without sacrificing efficiency or output power. The flyback topology also features a transformer’s primary and secondary windings in a single component, resulting in a more compact design.

The power switch in the RWS1500B15/RF is a high-speed complimentary MOSFET pair providing a high voltage breakdown rating of 200V and a forward blocking capability of up to 650V. The primary switch is controlled by a current-mode PWM controller that allows for quick reaction to load transients and swings in input voltage. The secondary control circuit employs a pulse-width modulated (PWM) voltage-mode controller that provides good load regulation and conversion efficiency.

An onboard overload protection circuit is incorporated to prevent over-current and short-circuit conditions. The power good output provides an indication of the state of the system, with a low level signal indicating normal operation and high-level signal indicating an overload or fault condition. The protection circuit also features a soft start control that ensures a gradual increase in output voltage at startup.

The RWS1500B15/RF is an efficient, cost-effective solution for a variety of applications, including medical equipment, telecom amplifiers, and industrial automation. It can be used in any application where reliability and low emissions are of utmost importance. Its wide input voltage range and high power rating make it ideal for applications in harsh environments.
