Medical
Medical environments demand continuous, conditioned power because outages or waveform anomalies can directly endanger patients on life-supporting equipment, corrupt imaging studies mid-acquisition, or interrupt sterile procedures. The recommended UPS set on the Standby Systems medical taxonomy page leans toward online double-conversion topology, with both transformerless (Sentinel Dual SDU) and transformer-based (Master MPS, Master HP, Master HE) options spanning small clinical equipment up to whole-facility scale.
Battery technology matters as much as the inverter — the same page surfaces high-rate VRLA battery families (ELGHR Batteries, VRLA Batteries) intended for short, intense discharges typical of medical UPS sizing. Inferred from product positioning: transformer-based topologies are favoured where galvanic isolation between mains and the inverter output is a clinical or regulatory requirement, but this isn’t directly stated on the page.

What to size for
- Continuous critical load (imaging, monitoring, theatre lighting) plus a buffer for inrush during cold-start scenarios
- Runtime sized to either bridge to a generator or hold for the duration of the longest tolerable interruption
- Redundant configurations (1+1 or N+1) for systems where single-UPS failure is unacceptable
- Galvanic isolation where required by the medical electrical equipment regime in the deployment country
Recommended products
- Sentinel Dual SDU — 4–10 kVA, online double-conversion, suitable for departmental loads (imaging suites, lab clusters)
- Master MPS — transformer-based three-phase UPS for facility-scale critical loads with galvanic isolation
- Master HP — transformer-based three-phase, broader capacity envelope
- Master HE — flagship transformer-based three-phase, positioned for largest facilities with TCO emphasis
