Mean Well IRM-30-15ST Switching Power Supply 3W 15V 2A - Encapsulated

Q: Can I use the IRM-30-15ST for a 15V PLC accessory, controller, or embedded automation board?

Yes, it provides a constant 15V output with up to 2A and 30W. That makes it suitable for 15V PLC accessories, embedded control boards, and other compact automation electronics that stay within those output limits.

Q: Is this power supply a fit for 15V industrial sensors, signal conditioners, or test modules?

It can be used for 15V sensors, signal conditioners, and test modules when the total demand remains within 2A and 30W. The 85-305VAC input range is also useful for equipment deployed across different AC mains conditions.

Q: Can the IRM-30-15ST support a compact 15V HMI or operator interface assembly?

It can support a compact 15V HMI or similar interface hardware if the load is within the 15V, 2A, and 30W rating. Its miniature encapsulated construction and 91.0 × 39.5 × 28.5 mm dimensions make it suitable where enclosure space is limited.

Q: Is the IRM-30-15ST intended for equipment that uses a screw terminal style power module?

Yes, this ST version is the screw terminal style model and delivers 15V constant voltage at up to 2A. It is intended for compact industrial, IT, or embedded equipment that needs a 30W encapsulated AC-DC supply.

Q: What are the main output choices around the IRM-30-15ST in the IRM-30 series?

The directly comparable IRM-30 models are IRM-30-5 and IRM-30-5ST at 30W, 5V, 6A; IRM-30-12 and IRM-30-12ST at 30W, 12V, 2.5A; IRM-30-15 and IRM-30-15ST at 30W, 15V, 2A; IRM-30-24 and IRM-30-24ST at 31.2W, 24V, 1.3A; and IRM-30-48 and IRM-30-48ST at 30.2W, 48V, 0.63A. This model is the 15V, 2A, 30W screw terminal style option in that group.

Q: Is the IRM-30-15ST suitable for outdoor equipment or wide-temperature locations?

It is rated for operation from -30°C to +70°C, so it can handle a broad equipment temperature range. No IP rating is listed, so it should be used inside a protective enclosure for indoor or shielded applications rather than exposed outdoor use.
