Core Target Markets
Explore how Astrodyne TDI solves complex electrical, electromagnetic, and environmental challenges across specialized commercial and industrial sectors.
Patient safety and zero downtime are critical in clinical environments. We design low-leakage AC/DC power supplies, isolation transformers, and mobile UPS units that meet strict safety requirements.
Wafer yield requires ultra-stable voltage outputs and high power density inside cleanroom environments. Our liquid-cooled power platforms eliminate cooling fans and dust contamination.
Industrial machinery operates under extreme temperatures, severe shock, and dirty AC mains. We engineer ruggedized power supplies and 3-phase EMI filters that protect sensitive controls.
Defending critical assets requires mission-ready durability. Our defense-grade COTS supplies and filter solutions suppress conducted emissions in high-threat electromagnetic environments.
Commercial equipment requires compact footprints, high efficiency, and quiet acoustic profiles. Our power designs maximize energy efficiency while keeping component costs competitive.
Smart grid infrastructure, battery storage, and renewable conversion demand high reliability under continuous operation. We supply customized power conversion and monitoring PDUs.

Advanced Thermal Engineering
Traditional forced-air cooling creates maintenance challenges, pulls dust into sensitive equipment, and reaches thermal limits in dense cabinets. Astrodyne TDI’s proprietary liquid-cooling platform delivers kilowatt-class power in ultra-thin 1U form factors, achieving unmatched power density and zero airflow contamination.
Grid Immunity & Compliance
Momentary grid voltage sags cause unscheduled tool aborts, damaged tooling, and thousands of dollars in scrapped semiconductor wafers. Our single-phase power conversion platforms are engineered with extended hold-up capacitance and active sag-response control to ride through utility dips smoothly.
Global Certification Framework
We eliminate regulatory uncertainty early in the development cycle by building safety, insulation, and EMC compliance directly into our base architectures.
ANSI/AAMI ES60601-1, IEC/EN 60601-1 3rd/4th Edition EMC, 2×MOPP isolation, low patient leakage current (<100µA).
UL 62368-1, IEC/EN 61000-6-2 / 61000-6-4, SEMI F47 voltage sag tolerance, CE, UKCA mark.

Procurement & Engineering FAQ
Key insights for engineering leaders, procurement managers, and system integrators evaluating power and EMI filter vendors.
We work directly engineer-to-engineer. Many OEM applications can be served by modifying an established platform—such as adjusting voltage rails, adding custom wiring harnesses, applying conformal coating, or altering mechanical mounting—which minimizes NRE costs and speeds time-to-market. For highly unique footprints or electrical specs, our engineering team designs complete ground-up custom solutions.
Unanticipated conducted or radiated noise failures during final agency testing cause severe schedule delays and costly redesign loops. By offering pre-compliance testing and EMI filter optimization in-house, we identify potential noise coupling paths early and tune filter topologies to guarantee adequate margin before formal submission.
Astrodyne TDI facilities operate under rigorous ISO 9001:2015 and medical-certified ISO 13485 quality systems. We enforce automated automated optical inspection (AOI), in-circuit testing, thermal cycling, and 100% full-load functional burn-in testing prior to shipment to ensure zero-defect delivery.
Liquid cooling removes heat up to 4x more efficiently than forced air. This enables extreme power density (kilowatt-class performance in 1U racks), eliminates fan failure modes, avoids acoustic noise, and prevents ambient air/dust movement in sensitive environments such as semiconductor fabs or sealed IP67 industrial enclosures.
