99.999% High-Availability Uptime
Continuous-duty operation engineered with premium conservative component derating to withstand 24/7 thermal stress without performance degradation.
Zero-Downtime Architecture
Engineered for 99.999% Uptime in High-Density Data Centers
In modern hyperscale, enterprise, and edge data centers, power failure is not an option. A single component outage can trigger catastrophic cascading downtime, costing thousands of dollars per minute in lost transactions and SLA penalties.
Since 1957, Acopian has designed and manufactured industrial-grade power supplies in the USA that deliver uncompromised reliability under continuous full-load operational conditions. Our server rack power systems, redundant modules, and high-efficiency switchers provide stable, clean DC power to mission-critical infrastructure worldwide.
- N+1 fault-tolerant redundant systems with built-in isolation diodes
- Hot-swappable plug-in power modules for zero-downtime maintenance
- Precision output voltage regulation (5 Vdc to 125 Vdc) with low ripple and noise
- 1U, 2U, 3U, and 4U 19-inch rack-mount configurations engineered for high thermal efficiency
Reliability by Design
Solving Critical Data Center Power Challenges
Data center loads present unique electrical and environmental demands. Acopian power supplies are built specifically to address high-density infrastructure vulnerabilities.
N+1 Redundancy & Active Sharing
Seamless paralleling with internal decoupling diodes ensures instantaneous fault isolation without disturbing the primary DC bus voltage.
Rack Density & Heat Management
Compact 1U and low-profile form factors designed to maximize power per rack unit while maintaining convection or internal fan-assisted thermal balance.
Hot-Swap Field Serviceability
Modular slide-in designs enable live replacement of power supplies while equipment remains fully operational, eliminating scheduled maintenance windows.
Proven Product Families
Data Center Power Supply Lineup
Acopian manufactures millions of standard and custom power supply configurations. These product families are specified most frequently by data center facilities engineers.
N+1 Redundant Power Systems
Configurable multi-output redundant packages (5 Vdc to 125 Vdc). Features active current sharing, status indicators, failure alarms, and hot-swap capability.
Rack Mount Power Supplies
Standard 19-inch 1U to 4U rack-mountable AC-DC and DC-DC power assemblies with meters, front-panel controls, and rugged heavy-gauge aluminum enclosures.
High-Efficiency Switchers

Engineering Insights
Direct Guidance From Senior Power Engineers
Technical considerations specified by Acopian's USA engineering team to maximize infrastructure lifespan and eliminate failure points.
Paralleling & Current Sharing
Proper diode isolation and active current balance prevent individual module overload and maintain true N+1 redundancy across all load levels.
Uninterrupted DC Flow
Rugged internal storage capacitance and fast dynamic response maintain steady DC output voltages during AC line voltage dips and rapid load steps.
Precision Remote Voltage Sensing
Built-in remote sense terminals automatically compensate for line voltage drops across long rack distribution cabling, ensuring exact voltage at the load.
Overvoltage Protection (OVP)
Fast-acting solid-state OVP circuitry safeguards expensive downstream servers, storage arrays, and network switches from transient overvoltage spikes.
Quality & Compliance
Certified. Documented. Traceable.
Every Acopian power supply is built in Easton, PA and Melbourne, FL, USA. Fully compliant with international quality standards and military/federal procurement requirements.
