Frequently Asked Questions
What output does the Mean Well IRM-01-3.3S provide?
The IRM-01-3.3S is a 1W encapsulated switching power supply with a single 3.3V DC output. Its rated output current is 300mA, making it suitable for low-power embedded and PCB-based applications.
What input voltage range does the IRM-01-3.3S support?
This model accepts a universal input range of 85 to 305VAC and also supports 120 to 430VDC. That wide range helps it fit products intended for global markets or systems with varying line conditions.
What kinds of applications is the IRM-01-3.3S typically used for?
The IRM-01-3.3S is intended for compact, low-power electronics that need a regulated 3.3V supply on a PCB. Its small encapsulated form factor and low standby consumption make it a practical choice for space-constrained industrial and commercial equipment.
Is the IRM-01-3.3S suitable for demanding temperature conditions?
This power supply is rated for operation from -30°C to +85°C, subject to the output derating curve. That gives it a relatively wide operating window for enclosed equipment or environments with significant temperature variation.
What protection features are included in the IRM-01-3.3S?
The IRM-01-3.3S includes short circuit, overload, and over voltage protection. Overload protection operates in hiccup mode with auto-recovery, and over voltage protection is specified at 115% to 135% of rated output voltage.
How compact is the Mean Well IRM-01-3.3S?
The PCB mounting version is specified at 33.7 x 22.2 x 15mm, while the SMD style is 33.7 x 22.2 x 16mm. This compact footprint is one of the main advantages of the IRM series for dense board layouts.
Does the IRM-01-3.3S meet recognized safety and EMC standards?
Yes. The product is approved to UL60950-1 and TUV EN60950-1, and its design refers to IEC60601-1, EN60335-1, and EN61558-1/-2-16. It also lists EMC compliance to standards including EN55022 Class B and EN55024.
Is the IRM-01-3.3S designed for low no-load power consumption?
Yes. Mean Well specifies no-load power consumption below 0.075W for this model. That makes it a good fit for equipment where standby efficiency matters.
