ET Series Industrial UPS: Power Behind Every Decision – Protecting Hospital Critical Medical Loads

Healthcare Infrastructure, Global — August 12, 2026 – Prostar ET Series industrial digital UPS delivers 0ms transfer, PF 1.0 full power factor, and DSP full digital control for critical medical loads in hospital environments. With 10-200kVA power range, 3-phase in / 3-phase out, and 380/400/415VAC voltage options, the ET Series ensures every critical decision has the power it needs – even when the grid falters.

Why Hospitals Require Specialized UPS Protection for Critical Medical Loads

In a modern hospital, critical power isn't about keeping every light on. It's about keeping the right systems running when they matter most. A hospital depends on more than medical expertise. It depends on the systems that support every critical decision.

Consider a single hospital:

• CT Imaging — Diagnostic decisions depend on image quality. A voltage sag can cause image artifacts or interrupt scanning mid-procedure.
• Operating Rooms — Surgical precision requires uninterrupted power. Surgical lights, anesthesia machines, electrosurgical units, endoscopy systems — any interruption can affect patient safety.
• Laboratory Diagnostics — Test results can't wait. Blood analyzers, chemistry analyzers, PCR equipment — samples have shelf life, results have urgency.
• Patient Monitoring — Every waveform matters. ECG, ventilators, EEG — any interruption can miss critical physiological changes.
• Medical Automation — Pharmacy automation, smart beds, pneumatic tube systems — operational efficiency depends on continuous power.

In healthcare, the most feared scenario is not a complete blackout — generators can take over. The real risk is a momentary instability that affects sensitive medical equipment.

The Hidden Threat: Micro-Interruptions in Healthcare

Hospital environments face power issues that often aren't "complete outages":

• 0.1 second voltage sag — CT scan may interrupt, requiring rescan — patient wait time extends, radiation exposure increases.
• 0.05 second transient — Operating room equipment may reboot — surgical rhythm breaks, patient safety at risk.
• Harmonic pollution — Patient monitors may false-alarm — clinical response resources wasted.

In healthcare, these are called micro-interruptions — the grid doesn't even notice, but hospital equipment does.

The ET Series doesn't just solve "what happens when power fails." It solves: "Can medical equipment continue running when power fluctuates?"

Prostar ET Series: Engineered for Critical Medical Loads

Prostar ET Series industrial digital UPS, covering 10kVA to 200kVA, 3-phase in / 3-phase out, output power factor 1.0, voltage options 380/400/415VAC. It represents a new generation of UPS technology — not just backup power, but power protection infrastructure for modern healthcare.

1. True Double Conversion Online — 0ms Transfer, Zero Interruption

True online double-conversion architecture delivers 0ms transfer time. Medical equipment always runs on stable, regulated power. In healthcare, 0ms transfer means CT scanning continues uninterrupted, surgical equipment stays online, and patient monitoring never loses a beat.

2. DSP Full Digital Control — Millisecond Response, Faster Than the Grid Can Fail

At the heart of the ET Series is DSP full digital control technology combined with IGBT Space Vector Pulse Width Modulation (SVPWM). This replaces analog circuits with digital precision — eliminating parameter drift, enabling faster detection, more accurate control, and superior stability. Millisecond response. Faster than the grid can fail.

3. PF 1.0 Full Power Factor — 100% Real Usable Power

Output power factor of 1.0 means every kVA is real usable power. 25% more load capacity than traditional 0.8 PF systems. For hospitals with complex medical load profiles, this translates to maximum efficiency and reserve capacity.
