It is designed to supply a variety of DC/AC power systems, offering continuous output power over a wide operating temperature range.

Working Principle

The R2S12-123.3/H-R DC-DC converter is a step-down converter, which means that it converts a higher DC voltage to a lower one. It uses the buck converter design, which consists of a high-side switch, a low-side switch, and an inductive or capacitive reactance. The converter has two independent switches, which act as a power switch. The high-side switch is connected to the input voltage and the low-side switch is connected to the output voltage. The switch will open and close as necessary to control the flow of current and voltage, and convert the input voltage to the desired output voltage.

When the high-side switch is open, the voltage across the inductor (L) is equal to the input voltage, and the current increases at a rate of the input voltage divided by the inductance (L). This current then flows through the low-side switch and will charge the output capacitance (C). When the low-side switch is opened, the voltage across the inductor (L) decreases and the current in the circuit decreases. This stored energy (Q) has to be equal to the average value of the input voltage as this is the only way the output voltage will remain constant.

The output voltage can be adjusted by changing the duty cycle of the switches, with a longer duty cycle providing a higher output voltage. The converter also offers automatic over-voltage, over-current, over-temperature, and short-circuit protection, ensuring high reliability and stable power.

In conclusion, the R2S12-123.3/H-R DC-DC converter is a reliable device, suitable for a variety of electronic systems. It is easy to use and offers adjustable output voltage, fast switching speed, and automatic protection. It is a great choice for those who require a reliable and versatile DC power conversion solution.
