DC-DC ConvertersDC-DC converters are electronic circuits or mechanical arrangements that converts electric energy from one of two sources, such as direct current (DC) or alternating current (AC) to another, usually with the same input voltage but with different output levels. Depending on the application, the devices can be either active or passive.REC3-243.3SRW/H2/A/M/SMD/CTRL-RThe REC3-243.3SRW/H2/A/M/SMD/CTRL-R is a DC-DC converter that is designed to offload the power network from high voltage areas of the system. This allows for the reduced power usage, resulting in lower total system cost. This converter is also equipped with a wide input voltage range from 9 to 36 volts. It has a low output current from 0.90 to 3.50 amperes and a regulated output current from 0.90 to 2.20 amperes.Its efficiency is around 95% at 40% load and up to 99% at full load. The output voltage is also adjustable from +14 V to +20 V. The overload protection for this converter is a short circuit current limitation, while its operating temperature range is from -40°C to +85°C. The dielectric strength of the isolation transformer is 4 kV / 10 kV.Application Field and Working PrincipleREC3-243.3SRW/H2/A/M/SMD/CTRL-R is mainly used for applications that require controllable current over a wide input voltage range, such as in power supplies, industrial automation, medical equipment, communications and audio equipment, lighting, and other similar applications.The working principle of this particular converter relies on a transformer that steps down the input voltage to a required level, which is then rectified into direct current (DC). The stand-by switch in the converter enables a low-consumption power mode, and the input power can be connected directly to the power circuit, with no need for additional components. The output voltage is then controlled by an internal adjustable reference or via an external signal.The voltage regulator ties itself into this power circuit and limits the current going through so as to maintain the output voltage at the desired level. The output current of the converter is monitored and controlled by a voltage feedback loop that can be programmed by the user. The regulator achieves stability and protects the converter by limiting the maximum output current and reducing the output voltage under over-load conditions.
