Frequently Asked Questions
What output does the Mean Well IRM-10-3.3 provide?
The IRM-10-3.3 is a 3.3V AC/DC switching power supply rated for 2.5A output current. Its maximum power rating is 8.25W, making it suitable for low-power embedded and PCB-based equipment that requires a regulated 3.3V supply.
What input voltage range does the IRM-10-3.3 support?
This model accepts a universal AC input range of 85 to 264VAC and also supports 120 to 370VDC input. That wide range helps it fit equipment intended for different regional mains standards without needing a separate input-specific version.
What kinds of applications is the IRM-10-3.3 best suited for?
The IRM-10-3.3 is designed for compact, board-level AC/DC power conversion in space-constrained equipment. Its encapsulated construction, miniature size, and 3.3V output make it a practical option for industrial electronics, control boards, and other low-power OEM applications.
What protection features are included in the Mean Well IRM-10-3.3?
This power supply includes short circuit, overload, and over voltage protection. The listed overload protection range is 115% to 190%, and over voltage protection is specified at 115% to 135% of rated output voltage.
How does the IRM-10-3.3 compare with larger open frame power supplies?
The IRM-10-3.3 is intended for lower-power applications where compact size and PCB integration matter more than higher wattage. Compared with larger open frame supplies, it offers a much smaller 45.7 x 25.4 x 21.5 mm form factor and 8.25W output, which is better suited to compact embedded designs.
Is the IRM-10-3.3 designed for low standby power and passive cooling?
Yes. Mean Well specifies no-load power consumption below 0.1W, and the unit is cooled by free air convection, so it does not require active fan cooling under normal operating conditions.
