FAQ

What is the output rating of the Mean Well IRM-03-15?

The IRM-03-15 is a 3W encapsulated switching power supply with a single 15V DC output. Its rated output current is 200mA, making it suitable for low-power embedded and PCB-based applications.

What input voltage range does the IRM-03-15 support?

This model supports universal input and operates across 85 to 305VAC or 120 to 430VDC. That wide range helps B2B buyers standardize on one part across equipment intended for different regional power environments.

Is the Mean Well IRM-03-15 a good fit for compact PCB applications?

Yes. The IRM-03-15 is designed as a compact encapsulated power module for PCB mounting, with dimensions of 37 x 24 x 15mm in PCB mounting style. Its small footprint and low 3W output make it a practical choice where board space is limited.

What protection features are included in the IRM-03-15?

The IRM-03-15 includes protection for short circuit, overload, and over voltage. Overload protection operates in hiccup mode with auto-recovery, and over voltage protection trips at 15.75 to 20.3V, shutting off the output via zener diode clamping.

Can the IRM-03-15 be used in demanding temperature conditions?

This model is rated for operation from -30°C to +85°C, subject to the output derating curve. That makes it suitable for equipment that may face wider ambient temperature variation than standard indoor electronics.

How does the IRM-03-15 differ from larger AC-DC power supplies?

The IRM-03-15 is intended for low-power applications that need a compact 15V, 200mA output rather than higher-wattage system power. Compared with larger AC-DC supplies, it emphasizes small size, low no-load power consumption under 0.075W, and PCB-level integration.
