SMPS

An SMPS power supply turns AC mains into a steady, regulated DC output for control circuits, PLCs, sensors and panel electronics. Panel builders, automation integrators, OEMs and dealers use this SMPS where a light, efficient supply is needed. As a switch mode power supply, it switches at high frequency,

so a power SMPS is far smaller and runs cooler than an old linear transformer unit. For panel cooling, see our axial fan range, and for neat terminations our cord end terminal ferrules.

SMPS Supply for Control Panels and Automation

Inside, the small high-frequency SMPS transformer is the reason the unit is light and compact. It takes AC in and gives steady DC out, which is why buyers looking for an AC and DC power supply for a panel usually need an SMPS. Size it with some headroom over the total load, mount it with space for airflow, and check the product page for input range and output rating.

Mount it on rail cut with a din rail cutter, wire it with cable lugs and ferrules, and keep the panel cool with an AC axial fan. Ashwin Tools ships orders direct with 10-day returns, and automation and electrical dealers can join our dealership programme.
