Where Aerospace Power Gets Tested

Aerospace and defense programs don't leave room for a power supply that almost works. Every spec gets checked, and every failure gets traced back to its source.

Signal-Level Noise Tolerances

Avionics and sensor circuits can't absorb switching noise or ripple. Linear regulation keeps the output clean where it counts.

Environmental Extremes

Temperature swings, vibration, and altitude push components past their rated limits. A ruggedized build option adds internal component staking for shock and vibration tolerance.

TAA and Buy American Requirements

Government and prime contracts often call for domestic sourcing. Every Acopian supply is made in the USA and available TAA compliant, standard or custom.

No Single Point of Failure

Flight-critical and ground support systems need N+1 configurations that keep running when one supply doesn't.

Your Power Supply Lineup

Acopian builds and ships over a million power supply models. These are the families most frequently specified for aerospace and defense programs.

Linear Regulated Power Supplies

Ultra-low noise, ultra-low ripple output for avionics, sensors, and instrumentation.

N+1 Redundant Power Systems

3.3–135 VDC, rack, wall, or DIN rail mount. Custom configurations available.

Custom Power Supplies

Full custom or modified-standard builds to exact program spec.

From Our Engineers

Technical resources from Acopian's engineering team, written for the engineers specifying power for flight-critical and ground support systems.

Linear vs. Switching Linear regulation keeps ripple and noise to a minimum, the standard for avionics and sensor circuits. Switching trades some of that margin for higher efficiency.

Redundant Power Supplies N+1 protection takes isolation diodes, voltage monitoring, and hot-swap-ready design, not just paralleled outputs, so one failed supply doesn't take the line with it.

Overvoltage Protection Fast-acting OVP clamps a sensing or wiring fault to within roughly 15% of rated output, before it reaches a load that can't be swapped out mid-mission.

Remote Sensing Remote sensing corrects for voltage drop on long wire runs by regulating at the load itself, through dedicated +SENS/-SENS leads.

Certified. Documented. Traceable.

Acopian power supplies are built in the USA.
All standard and custom configurations are available TAA compliant.

We choose Acopian power supplies because of their rapid response in shipping.

If Acopian made automobiles. I'd buy one without question..

The power supplies we have purchased from Acopian are top quality.

We're most impressed and appreciative for Acopian's extraordinary customer service.
