TRA 3-0513

DC/DC Converter TRA 3 Series, 3 Watt • • Semi-regulated output (load) • • • • Industry standard pinout • 3-year product warranty Highest power density 3W SIP-Converter High efficiency up to 89% I/O isolation voltage 1000 VDC Operating temperature range –40°C to +95°C UL 62368-1 IEC 62368-1 The TRA 3 series are miniature, I/O-isolated 3W DC/DC-converters with a semi load regulation. They are the ideal solution to power drivers and circuits where unregulated DC/DC converters do not meet the input voltage range at load change Models Order Code Input Voltage Output Voltage Output Current Efficiency Range nom. max. typ. 5 VDC 600 mA 83 % TRA 3-0511 9 VDC 333 mA 87 % 12 VDC 250 mA 86 % TRA 3-0513 15 VDC 200 mA 88 % TRA 3-1211 5 VDC 600 mA 84 % TRA 3-0519 TRA 3-0512 4.5 - 5.5 VDC (5 VDC nom.) 9 VDC 333 mA 88 % 12 VDC 250 mA 88 % TRA 3-1213 15 VDC 200 mA 89 % TRA 3-2411 5 VDC 600 mA 82 % TRA 3-1219 TRA 3-1212 TRA 3-2419 TRA 3-2412 TRA 3-2413 www.tracopower.com 10.8 - 13.2 VDC (12 VDC nom.) 21.6 - 26.4 VDC (24 VDC nom.) 9 VDC 333 mA 85 % 12 VDC 250 mA 86 % 15 VDC 200 mA 85 % September 20, 2023 Page 1 / 4 TRA 3 Series, 3 Watt Input Specifications Input Current - At no load 5 Vin models: 12 Vin models: 24 Vin models: 5 Vin models: 12 Vin models: 24 Vin models: 5 Vin models: 12 Vin models: 24 Vin models: 5 Vin models: 12 Vin models: 24 Vin models: - At full load Surge Voltage Recommended Input Fuse Input Filter 50 mA typ. 40 mA typ. 30 mA typ. 700 mA max. 285 mA max. 150 mA max. 9 VDC max.
