Zero-Downtime Power Backup Solutions
Uninterruptible Power Supplies (UPS) for Critical Applications
Engineering continuous, isolated backup power with 2MOPP medical safety rating, double-conversion online topology, and long-life LiFePO4 battery architectures for surgical systems and mission-critical OEM electronics.
Failure-Critical Uptime Engineering
Medical-Grade & Industrial Uninterruptible Power Systems
In an operating room, automated fab line, or tactical environment, momentary power dropouts cause catastrophic tool aborts, corrupt sensitive telemetry, or compromise patient safety. Standard standby generators require up to 30 seconds to spin up and switch over—an unacceptable window for modern surgical robotics and mission-critical data processors.
Astrodyne TDI’s Uninterruptible Power Supply (UPS) platforms combine online double-conversion power conditioning, zero transfer switch time (0 ms delay), and certified galvanic isolation. Operating under ISO 9001:2015 and ISO 13485 quality systems, our UPS units eliminate total utility blackouts, voltage sags, frequency fluctuations, and line harmonics before they reach sensitive microprocessors.
How Double-Conversion UPS Protection Works
1. AC-to-DC Rectification: Incoming utility AC power is continuously rectified into regulated DC voltage, filtering out line noise, surges, and spikes.
2. Energy Buffering & Battery Management: Internal LiFePO4 battery arrays maintain optimal charge through individual cell monitoring and temperature compensation.
3. DC-to-AC Inverter Output: The inverter generates pure sine wave AC output to the load at all times, delivering completely glitch-free power transfer during grid loss.

Engineering FAQ
Uninterruptible Power Supplies Technical Questions
Direct technical insights from our applications engineering team regarding UPS selection, compliance, and custom modification options.
A medical-grade UPS incorporates reinforced isolation barriers providing 2×MOPP (Means of Patient Protection) and 2×MOOP (Means of Operator Protection), low earth leakage current (<300µA), and dielectric withstand ratings up to 4000 VAC. This design permits safe deployment within the patient vicinage without requiring bulky external isolation transformers.
Online double-conversion continuously converts utility AC to DC, and then back to pure sine wave AC output. Because the inverter is always supplying power to the load, there is true 0 ms transfer time during an AC grid failure. Standby or line-interactive UPS systems exhibit switchover delays (4–10 ms) that can drop sensitive microprocessors or interrupt robotic surgeries.
Lithium Iron Phosphate (LiFePO4) offers significantly higher energy density (up to 60% weight reduction), an operational lifespan of up to 10 years (3,000+ charge cycles compared to 300–500 cycles for SLA), rapid recharge capabilities (reaching 90% capacity in ~2.5 hours), and superior thermal stability without thermal runaway risk.
