What is the difference between an AC-DC converter module and a DIN rail power supply?

An AC-DC converter module is an encapsulated, board-mount component soldered directly onto the PCB and is used when space and BOM count are critical. A DIN rail AC-DC power supply is a fully enclosed unit that clips onto a 35 mm rail inside a control cabinet, includes terminal blocks and is preferred for field wiring, retrofits and panel builds.

Which isolation voltage should I specify for industrial designs?

For signal isolation and low-voltage control loops, 1.5 kVDC is usually sufficient. Industrial bus systems and motor drives typically require 3 kVDC, while railway and high-transient environments call for 4 kVDC or more. Medical applications require reinforced 2xMOPP insulation with low leakage current per IEC 60601-1.

Does Aimtec support custom power supply requirements?

Yes. Aimtec engineering teams modify standard platforms for output voltage, pin-out, footprint, coating, connector and certification needs, allowing OEMs to shorten qualification cycles while keeping proven topologies.
