ETMA120250UD-P5RP-IC Application Field and Working Principle

The ETMA120250UD-P5RP-IC from ETM (Electronic transformer manufacturer) is an AC/DC Desktop and Wall Adapter that converts AC to DC power, enabling DC power adapters used in many industrial applications that may not require a large power source. The ETMA120250UD-P5RP-IC also works as an intermediate power distribution device, allowing a large, heavy DC voltage to be converted down into a lower voltage range.

The ETMA120250UD-P5RP-IC has an input voltage range of 100-240 Vac and a maximum output current of 2.5A. The working temperature range of this AC/DC Adapter is -40°C to 85°C, so it is suitable to be used in a wide range of environments. The ETMA120250UD-P5RP-IC is designed to provide a stable output voltage and features protection functions such as over voltage, over current and reverse current protection. It offer users the option to select via dip switches the output voltage, allowing the device to be used in either polarity.

The ETMA120250UD-P5RP-IC is based on a modified bridge rectifier circuit, which uses four diodes and an inductor. The AC line is rectified by the diode bridge, providing a DC voltage output. The inductor is used to filter out the ripples, allowing a stable DC output. The output voltage is regulated by controlling the time interval in which the SCR or TRIAC turns on. The output is monitored to ensure that it remains within the accepted voltage range.

The ETMA120250UD-P5RP-IC is an extremely versatile device, as it is suitable for a wide range of applications, from industrial applications such as power supplies for computers, telecoms, medical instruments and test and measurement equipment, to domestic use as a power adapter for home appliances such as a laptop, television and refrigerator.

The ETMA120250UD-P5RP-IC has been tested and approved for safety. It is supplied with CE, UL and CB certificates, meeting the safety requirements of the IEC/EN 61558 and other related safety standards.
