Input power connects to VCC1 (Pins 8, 9) and GND1 (Pins 4, 5).

Integrating the BDM41 series DC-DC converter steps down and isolates 24V bus power into clean, regulated 5V or 12V rails for microcontrollers, optocouplers, and ADC converters, safeguarding delicate digital circuitry from common-mode electrical noise.\u003c\/p\u003e\n\u003ch3\u003e2.

Why is an external input fuse mandatory for the BDM41 series?\u003c\/h3\u003e\n\u003cp\u003eBecause switching power supply modules do not contain internal catastrophic fuses, connecting a recommended 50VDC 8A slow-blow fuse in series with the positive input line (VCC1) provides essential over-current protection against supply surges and meets safety compliance standards.\u003c\/p\u003e\n\u003ch3\u003e2. Can I connect the input GND1 and output GND2 together on my PCB?\u003c\/h3\u003e\n\u003cp\u003eNo. Connecting GND1 and GND2 together completely bypasses the internal high-frequency isolation transformer, causing loss of the 2000VDC galvanic isolation barrier and exposing downstream digital electronics to input ground loop noise and voltage spikes.\u003c\/p\u003e\n\u003ch3\u003e3. How do I use the TRIM pin (Pin 14) to adjust output voltage?\u003c\/h3\u003e\n\u003cp\u003eThe TRIM pin allows precise +\/-5% or +\/-10% fine-tuning of the output voltage to compensate for long PCB trace voltage drops. Connecting a trim resistor between TRIM and VCC2 trims the output voltage down, while connecting a trim resistor between TRIM and GND2 trims the output voltage up.\u003c\/p\u003e\n\u003ch3\u003e4. Does the BDM41 series require an external heat sink under full load?\u003c\/h3\u003e\n\u003cp\u003eUnder standard ambient conditions up to +40 deg C, the module operates reliably with natural air convection cooling due to its high conversion efficiency (up to 87.5%). When operating at elevated ambient temperatures up to +85 deg C, refer to the official power derating curve in the user manual to maintain reliable operation.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Ebyte Official Store - IoT Module Manufacturer","offers":[{"title":"BDM41-30W24S05G2","offer_id":48846901543117,"sku":"BDM41-30W24S05G2","price":8.51,"currency_code":"USD","in_stock":true},{"title":"BDM41-30W24S12G2","offer_id":48846901575885,"sku":"BDM41-30W24S12G2","price":8.51,"currency_code":"USD","in_stock":true},{"title":"BDM41-30W24S24G2","offer_id":48846901608653,"sku":"BDM41-30W24S24G2","price":8.51,"currency_code":"USD","in_stock":true},{"title":"BDM41-40W24S05G2","offer_id":48846901641421,"sku":"BDM41-40W24S05G2","price":9.12,"currency_code":"USD","in_stock":true},{"title":"BDM41-40W24S12G2","offer_id":48846901674189,"sku":"BDM41-40W24S12G2","price":9.12,"currency_code":"USD","in_stock":true},{"title":"BDM41-40W24S24G2","offer_id":48846901706957,"sku":"BDM41-40W24S24G2","price":9.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0615\/5911\/1885\/files\/3034a1133efe01daba919094b70c6310_303b5115-b966-4c64-a522-f66b5ca483d1.jpg?v=1793181696","url":"https:\/\/ebyteiot.com\/hi\/products\/bdm41-series-30w-40w-isolated-dc-dc-converter-9-36v-dip","provider":"Ebyte Official Store - IoT Module Manufacturer","version":"1.0","type":"link"}
