Lambda HWS1500-24 High-Power Water-Cooled Switch Mode Power Supply

Lambda HWS1500-24: Industrial-Grade Water-Cooled Power Supply for Demanding Environments

You’ll find this unit holding down the fort in places where regular power supplies would tap out—think steel mills running continuous casting lines or semiconductor fabs with 24/7 plasma etchers. The HWS1500-24 handles sustained high-load operations without breaking a sweat, especially where ambient temps regularly hit 45°C and dust clogs air-cooled alternatives. Fact is, we’ve seen plants ditch three air-cooled units per year for one of these water-cooled workhorses.

Plant managers in aluminum smelters and paper mills keep coming back for these—especially when their old air-cooled units keep tripping during summer heatwaves. We’ve got the HWS1000-24 handling control cabinets for ABB AC800PEC systems, while the beefier HWS2000-48 powers GE Mark VIe turbine controllers. One pulp mill engineer told us how they slapped this into their Triconex 3721 rack after two failed attempts with fan-cooled supplies; hasn’t missed a beat in 18 months despite 90% humidity and conductive dust everywhere.

What really sets this apart is how it handles thermal stress—water cooling means no more cleaning clogged fans every other week. The internal bus design spreads heat evenly across those copper cold plates, so you don’t get hot spots frying components like in cheaper units. Personally, I’ve seen these run rock-steady when ambient hits 55°C as long as the coolant stays below 60°C. They play nice with Foxboro FBM240 modules and Bently Nevada 3500 racks since the ripple stays under 50mV peak-to-peak. Oh, and the dual-redundant overtemp sensors? Lifesaver when your coolant pump decides to take a coffee break mid-shift. Just don’t expect fancy IoT features—it’s a power supply, not a smartphone.
