Switch Mode Power Supplies

Switch-mode power supplies convert the AC mains to clean, regulated 24VDC that PLCs, sensors, relays, and HMI panels depend on for reliable operation around the clock. Our SMPS inventory spans single-phase and three-phase input units, from compact 15W logic supplies to high-power 960W units for large control panels, from Siemens (SITOP), Phoenix Contact (QUINT), ABB, Mean Well, PULS, and Weidmuller. When selecting a power supply, consider the total DC load (with 20 to 30 percent headroom for inrush and future expansion), input voltage range, output voltage adjustability, efficiency rating, and whether you need built-in redundancy or buffer modules for short-term hold-up. We stock the most-requested 24VDC 5A, 10A, and 20A units for immediate dispatch, with larger ratings and specialized output voltages available on short lead time.
