NON-ISOLATED DC/DC CONVERTERS Vdc Input Vdc - Vdc/3 A Output • Non-Isolated • High Efficiency • Low Cost • Excellent Thermal Performance • Input Under Voltage Lockout • OCP/SCP • Wide Range Trim • Remote On/Off • Industrial Temperature Range • UL60950-1 Recognized UL/cUL The Bel xRAH-03C1A0 modules are a series of non-isolated, step down dc/dc converters that operate from a nominal Vdc source. These converters are available in a range of output voltages from Vdc to Vdc. It is packaged in a compact, overmolded package rated at 3 A. Optional lead forming provides a vertical mount product for minimal footprint or a surface mount option for a very low profile. The output is closely regulated and the efficiency for Vdc output is typically 93% at full load. Typical features include remote on/off, input under voltage lockout, over current protection and short circuit protection. Part Selection Output Voltage Vdc - Vdc Input Voltage Vdc Max. Output Current 3A Max. Output Power W Typical Efficiency 93% 93% 89% 87% 84% 81% Part Number Surface Mount SRAH-03C1A0 SRAH-03C250 SRAH-03C180 SRAH-03C150 SRAH-03C120 SRAH-03C090 Part Number Vertical Mount VRAH-03C1A0 VRAH-03C250 VRAH-03C180 VRAH-03C150 VRAH-03C120 VRAH-03C090 Notes Add “0” suffix at the end of the model number to indicate “Tube Packaging”, and “R” for “Reel Packaging”, and “G” for “Tray Packaging”.
