The device is also suitable for use in military, industrial and aerospace applications, as it provides high reliability and optimal performance in these environments. The unit is also available in a RoHS compliant version.

The R0.25S12-0505/HP DC-DC Converter operates by entailing a forward converter circuit, which consists of a primary and secondary coil. The primary voltage is rectified and then fed into a power switch, which can use a transistor, a thyristor or a MOSFET. This switch is then used to control the current of the transformer. The transformer’s secondary coil is then rectified again, providing the output voltage.

The device works on the principle of pulse-width modulation (PWM), which involves varying the average voltage over a period of time. This is done by controlling the frequency and duty cycle of the pulses applied to the primary coil. The higher the duty cycle, the higher the average output voltage will be. On the other hand, the lower the duty cycle, the lower the output voltage.

The R0.25S12-0505/HP DC-DC Converter offers an extensive variety of features, which include: adjustable output voltage, overvoltage protection, overload protection, over-temperature protection, and adjustable overload current limiting. The device is also EMC and WEE compliant, ensuring that it does not interfere with other surrounding electronics.

In summary, the R0.25S12-0505/HP DC-DC Converter is a highly reliable and efficient converter, which provides a variable output voltage of – 0.25V to +14V, yielding up to 50 Watts of power. It is suitable for a variety of applications and operating environments, including military, industrial and aerospace. The internal switch-mode design allows for easy installation on circuit boards. Furthermore, the device is EMC and WEE compliant, ensuring compliance with European directives.
