FAQ
What is the output rating of the Mean Well IRM-02-5?
The IRM-02-5 is a 2W AC-DC switching power supply with a regulated 5V DC output. Its rated output current is 400mA, making it suitable for low-power embedded and PCB-mounted electronics.
What input voltage range does the IRM-02-5 support?
This model accepts a universal input range of 85 to 305VAC, and it also supports 120 to 430VDC input. That wide range makes it a practical option for equipment intended for different global mains environments.
Is the IRM-02-5 a good choice for compact PCB applications?
Yes. The IRM-02-5 is designed as a compact encapsulated module-type power supply with dimensions of 33.7 x 22.2 x 15mm in PCB mounting style. Its small footprint helps when board space is limited and a low-power onboard supply is needed.
What protections are built into the Mean Well IRM-02-5?
The IRM-02-5 includes short circuit, overload, and over voltage protection. Overload protection operates in hiccup mode with auto-recovery, and over voltage protection is specified at 5.2V to 6.8V, shutting off the output with zener diode clamping.
What operating environment is the IRM-02-5 rated for?
This power supply is rated for operation from -30°C to +85°C, subject to the output derating curve. It is cooled by free air convection, has isolation class II construction, and leakage current is specified at less than 0.25mA at 277VAC.
How does the IRM-02-5 compare for low standby power applications?
One of the key advantages of the IRM-02-5 is its very low no-load power consumption of less than 0.075W. That makes it a strong fit for designs where standby efficiency and minimizing wasted power matter.
