The Emerson / Artesyn Technologies LPS202-M is an open-frame AC-DC power supply engineered for integration into space-constrained industrial, telecommunications, and medical equipment. Its compact 3″ × 5″ footprint and sub-1U height (1.5″) enable deployment in systems requiring small form factors without sacrificing reliability. The unit delivers 5 V main output with 100 W convection-cooled capacity or 200 W with 30 CFM forced air cooling, supported by a 12 V @ 1 A isolated auxiliary fan output. Active Power Factor Correction (PFC) achieves 0.99 typical efficiency across 90–264 VAC and 120–300 VDC inputs at 47–63 Hz. ITE and medical safety approvals cover non-patient contact and non-patient critical applications.
