Frequently Asked Questions
What is the Mean Well IRM-03-5 designed for?
The IRM-03-5 is a compact encapsulated AC-DC switching power supply designed to provide a regulated 5V DC output at up to 600mA. With a 3W power rating and small footprint, it is suited to space-constrained PCB-based equipment and embedded industrial or commercial electronics.
What are the main electrical ratings of the IRM-03-5?
This model is rated for 3W total output power and delivers 5V DC with a rated current of 600mA. It accepts a universal input range of 85 to 305VAC or 120 to 430VDC, which makes it suitable for designs intended for broad global input conditions.
What protection features are included in the Mean Well IRM-03-5?
The IRM-03-5 includes short circuit, overload, and over voltage protection. Its overload protection operates in hiccup mode with auto-recovery, and over voltage protection is specified at 115% to 135% of rated output voltage.
Is the IRM-03-5 suitable for low standby power applications?
Yes. Mean Well specifies no-load power consumption of less than 0.075W for the IRM-03-5, which is useful for designs that need to minimize standby energy use. This can make it a practical option for always-on equipment with strict idle power targets.
What operating temperature range can the IRM-03-5 handle?
The specified working temperature range is -30°C to +85°C, subject to the output derating curve. That gives this model a broad operating window for equipment used in demanding indoor enclosures or variable ambient conditions.
What certifications and compliance standards are listed for this power supply?
The IRM-03-5 is listed with UL60950-1, TUV EN60950-1, and TUV EN60335-1 approvals, with design reference to IEC60601-1 and EN61558-1/-2-16. EMC standards listed include EN55022 Class B, EN61000-3-2, EN61000-3-3, EN61000-4 series, and EN55024.
