DC DC Converters

The RS-4815SZ/H3 is an isolated DC-DC converter designed to provide reliable, isolated and efficient power conversion in a wide range of applications. It is a switch mode power supply that features up to 500 watts of output power and high efficiency ratings of up to 94%.

Application Field

The RS-4815SZ/H3 is suitable for use in a wide range of applications, including:

• Uninterruptible Power Supply (UPS)
• Industrial Automation
• Test & Measurement Equipment
• Power Grid

The RS-4815SZ/H3 is well suited for various applications, such as powering industrial equipment and for data acquisition systems where high efficiency and high reliability are required.

Working Principle

The RS-4815SZ/H3 employs an isolated switching converter topology in order to provide the high efficiency and reliability. It utilizes pulse width modulation (PWM) and operates at a constant frequency of 100kHz. The PWM also ensures that the output voltage is regulated and is not affected by input voltage variations.

This converter includes an onboard active current sharing feature, which is especially useful when two or more converters are used in parallel. This feature allows the converters to work together at the same output current, and allows for reliable and efficient operation in the long run.

The RS-4815SZ/H3 includes a wide input voltage range of 4.5V to 18V, which allows for operation in a wide variety of input sources. It also includes internal over-temperature, current sharing and over-current protection features.
