TIDA-00127, 30W Ultra Wide Range Power Supply for Protection Relays Reference Design

TIDA-00127, 30W Ultra Wide Range Power Supply for Protection Relays Reference Design. This power supply solution for Protection Relays handles an ultra-wide range of both (88-276V AC) and DC (24-250V DC) inputs making it a suitable platform to power a variety of Protection Relays. The power supply is designed to output industry standard voltages (such as 12V and isolated 6.75V) required in many Protection Relays while also providing excellent line and load regulation (< 3%). This solution has been engineered for high wattage (30W) with good efficiency (up to 78%) and has also been pre-compliance tested for IEC61000-4 (EFT and Surge) and CISPR 11 Class A (Interference)
