The BPWX 2-14-50 from Cita Technologies is a Drop-in Switching Power Supply Module that steps down an AC input voltage of 90 - 308 V to a DC output voltage of up to 14 V. This converter delivers an output power of up to 2 W and has an efficiency of 70%. It is engineered to offer quiet operation with synchronized switching that occurs only 10% of the time, which minimizes the electromagnetic interference and reduces the need for additional filtering or shielding. This micro-sized converter does not require a current limit margin and allows the charging of large supercapacitors faster than standard SMPS modules with twice the power rating. It is available in a through-hole package that measures 34.214 x 28.372 x 14.757 mm and is ideal for smart sensors, smart meters, smart lighting, smart grid, M2M or IoT, and other control applications.
