Robust, Repeatable Performance in a Space-Saving Package
You are designing the most technically advanced systems in the world. Power to exacting specifications — tight regulation, low ripple, predictable thermal behaviour — is not a line item; it is the difference between a qualified design and a field failure.
Since 1957, Acopian power supplies have been specified by engineers in aerospace, space, defense, semiconductor, telecommunications, medical, energy, oil & gas and transportation programs. Every unit is built to order, burn-in tested and serialized at our own USA facilities — never re-badged, never sourced from an unknown supply chain.
What engineers gain by specifying Acopian
- Regulated linear, switching, unregulated and high voltage topologies from one qualified vendor
- Metal-enclosed construction with UL 508, PFC and universal-input options
- Documented datasheets, CAD drawings and input current data for design files
- Direct access to application engineers — no automated phone trees

Why Choose Acopian
Engineers Don't Buy a Power Supply — They Buy a Promise
In an industry of opaque lead times, questionable supply chains and automated call queues, we built our reputation on a different model: manufacture everything ourselves, answer the phone with an engineer, and ship when we say we will.
Designed & Built in the USA
Every unit is manufactured in Easton, PA and Melbourne, FL — TAA compliant and traceable through an ISO 9001:2015 system.
Talk to an Engineer Now
During business hours your call reaches a sales associate or application engineer — no menu trees, no ticket queues.
3-Day Build & 5-Year Warranty
3-day models ship within three business days; larger systems within nine. Each one is built fresh after your order, not pulled from aging stock.
“Acopian power supplies are very reliable and your delivery dates can't be beat.”
Case Study
Helping the Aerospace Industry Take Off at Full Power
An industry-leading aerospace manufacturer designed a complete flight system and needed a partner to produce the custom power supplies behind it. Acopian delivered four separate rack-mounting power systems, engineered to operate together and supply linear regulated DC power to every cockpit component.
- Four coordinated 19" rack-mount power systems
- Linear regulated DC outputs for noise-sensitive avionics
- Custom wiring, metering and front-panel layout to the customer's drawing
- Delivered on the program schedule with full documentation
Experience You Can Verify
The Partner You Can Depend On
Dependability defines our service just as much as our hardware — from our 3-day shipping promise to nearly seven decades of American manufacturing.

How to Select the Best Power Supply for Your Application
A practical engineering framework for comparing linear vs. switching topologies, calculating derating and thermal headroom, evaluating ripple and regulation limits, and deciding when a custom or N+1 redundant system is the safer specification.
Buyer FAQ
What Global Buyers Ask Acopian Most
Straight answers on lead time, compliance, warranty and customization — the four questions that decide most power supply purchase orders.
Most Acopian 3-day models are freshly built and shipped within three business days of the order. Larger power systems and multi-output custom assemblies typically ship within nine business days. Because units are built to order, you receive newly manufactured hardware rather than long-stored inventory.
Yes. Every Acopian power supply is designed, built and tested in our own facilities in Easton, Pennsylvania and Melbourne, Florida. Our products are TAA compliant, which supports US government, defense and federal integrator procurement requirements.
Acopian metal-enclosed power supplies carry a 5-year warranty. Manufacturing is governed by an ISO 9001:2015 certified quality management system, with documented test records for traceability in regulated programs.
Yes. Beyond millions of standard configurations, our engineers design custom single and multi-output supplies, rack-mount systems, NEMA 4X enclosed units and N+1 redundant architectures. The Custom System Builder lets you configure a system with one to five outputs and submit it directly to engineering.
Acopian covers every output from 0 Vdc through 30 kVdc in single, dual, triple, wide-adjust, constant current and high voltage forms. Mounting options include DIN rail, wall mount, 19" rack mount, chassis/modular, low profile and NEMA 4X enclosed packages.
