REM6-1212S/A/CTRL

DC-DC converters are a type of power supply that enable the conversion of one DC voltage level to another. They are used for applications that require two different supply voltages, such as a motor that needs 24 volts but the rest of the system operates at 12 volts. The REM6-1212S/A/CTRL DC-DC converter is a switching converter that provides isolated power from an input of 6 to14 volts to an output of 12 volts at 2A. It includes built-in protection features that guard against over-current, over-voltage and over-temperature conditions to ensure the reliability and safety of a system.

The REM6-1212S/A/CTRL converter is a synchronous rectifier, step-down converter with a switching frequency of 300 kHz and a power efficiency of 88%. It has an adjustable output voltage from 0.8 V to 12 V with +/- 2.5 % accuracy, and can deliver a continuous output current of up to 2 A. The converter has built-in over-voltage protection and short-circuit protection, allowing it to safely operate for a wide range of voltages and currents. Additionally, it has an adjustable soft-start feature to limit inrush current.

The primary application of the REM6-1212S/A/CTRL is motor control that requires an isolated power supply. It is often used in applications such as robotics, refrigeration systems, and audio equipment, where high power and efficiency are necessary.

The working principle of the REM6-1212S/A/CTRL converter is based on a synchronous rectifier circuit that uses pulses from a high frequency square wave oscillator to drive two power switching elements. The oscillator generates a constant frequency, alternating voltage waveform on the input side of the converter. When the switches are on, current is allowed to flow from the input to the output, and when they are off, current stops flowing and the converter is isolated from the input. The duty cycle of the oscillator controls the voltage and current on the output side. The frequency of the oscillator is then adjusted to adjust the output voltage.

In addition, there is a control circuit that monitors the output voltage and adjusts the duty cycle accordingly. This ensures that the output remains within the desired range. The control circuit also features an over-voltage protection, which shuts off the converter when the output voltage exceeds the maximum allowable range.

The REM6-1212S/A/CTRL DC-DC converter is a reliable and versatile power supply for a wide variety of applications. Its high power efficiency and protection features make it well-suited for motor control, audio equipment, and many other applications that require isolated power supply.
