Frequently Asked Questions
What input voltage range and output power does the THN 30-4812WI support?
The THN 30-4812WI accepts a wide 4:1 input voltage range from 18 V to 75 V DC and delivers 30 W of regulated 12 V DC output, making it compatible with 24 V and 48 V industrial bus systems as well as battery-backed supplies with significant voltage fluctuation.
How does the THN 30-4812WI ensure isolation between input and output circuits?
The THN 30-4812WI provides 1500 VDC galvanic isolation between its input and output, protecting downstream 12 V circuits from high-voltage transients on the 48 V input bus and meeting safety requirements in industrial control, railway traction systems, and medical auxiliary power applications.
What operating temperature range can the THN 30-4812WI handle in field-installed equipment?
The THN 30-4812WI is rated for full 30 W operation across a -40°C to +85°C ambient temperature range, allowing deployment in outdoor cabinets, railway rolling stock, and industrial enclosures without requiring additional cooling measures or power derating under normal conditions.
For a 48 V telecom system powering 12 V boards, how efficient is the THN 30-4812WI at full load?
The THN 30-4812WI achieves typical efficiency above 88% at full 30 W load when converting from a 48 V input to 12 V output, reducing heat dissipation to approximately 4 W, which is manageable within the 1.0 inch × 1.0 inch encapsulated metal package without forced-air cooling.
