SDM30 series – High-power DC/DC converters for printed circuit board from MEAN WELL


In order to simplify the creation of a power supply system, MEAN WELL produces specialized modules – DC/DC converters installed on the printed circuit board of the end device. In order to provide power to a load with a power of up to 30 Watts, one of the best choices will be a powerful DC/DC converter of the SDM30 series, which has small dimensions and pin locations for mounting on a printed circuit board through holes (through-hole technology, THT).

Внешний вид DC/DC преобразователя серии SDM30The appearance of the SDM30 series DC/DC converter

The SDM30 series has three input voltage ranges – 12V (9.2 to 18V), 24V (18-36V), 48V (36-72V). The rated output power (related to the output voltage) is from 16.5 to 30W. The output voltage is also selected from a number of the most applicable in the power supply of various devices: 3.3, 5, 12, 15V. SDM30 converters have the following features: doubled input voltage range, metal housing, large input and output capacitances (1000pF), high withstand voltage (1000V between input and output), basic protection against failure – short circuit, overload, overvoltage. Additional functions are also implemented in SDM30 converters – remote ON/OFF (ON/OFF Control) and output voltage adjustment within ± 13% (Trimming Output).
