Power Built to Utility-Grade Standards

High-voltage power supplies for generation, substation, and grid monitoring equipment. Made in the USA.

Where Grid Power Gets Tested

Generation and substation equipment runs continuously, outdoors, and often at voltages a standard bench supply wasn't built for.

High-Voltage Test & Calibration

Protection relays, switchgear, and insulation testing need a stable, adjustable high-voltage source.

Continuous, Redundant Operation

Grid monitoring and control systems can't go dark because one supply failed. N+1 configurations keep them running.

Outdoor, Substation-Grade Enclosures

Equipment sited at a substation or generation facility needs to handle weather and vibration, not just a rack indoors.

Domestic Sourcing for Public Infrastructure

Utility and federal energy projects often carry TAA and domestic-sourcing requirements. Every Acopian supply is made in the USA.

Your Power Supply Lineup

Acopian builds and ships over a million power supply models. Here's what's most frequently specified for energy and power infrastructure.

High Voltage Power Supplies

1,000–30,000 VDC output, adjustable, with arc and short-circuit protection.

N+1 Redundant Power Systems

Rack, wall, or DIN rail mount for continuous operation.

Custom Power Supplies

Full custom or modified-standard builds, including NEMA-enclosed options for outdoor and substation equipment.

From Our Engineers

Technical insight from Acopian's engineering team for generation, substation, and grid equipment.

Acopian industrial wall-mount power supply

Overvoltage Protection Fast-acting OVP clamps a sensing or wiring fault to within roughly 15% of rated output, before a grid transient reaches downstream instrumentation.

Redundant Power Supplies N+1 protection needs isolation diodes, voltage monitoring, and hot-swap-ready design. Paralleled outputs alone can't guarantee it.

Remote Sensing Remote sensing corrects for voltage drop on long runs to remote metering and monitoring equipment by regulating at the load itself.

Keep Machines Operational A single power supply failure can take grid monitoring offline right when it's needed most. N+1 redundancy keeps it running through the failure.

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.
