Custom Electrical Control Panels, Engineered to Your Specification

UL508A control panels for utility, industrial, and harsh-environment applications — designed, wired, tested, and documented by engineers, not just assembled to a drawing.

Built to your exact electrical and wiring specification
UL508A panel shop — point-to-point testing and full documentation included
Rated for harsh environments: dust, vibration, moisture, and temperature extremes
Low-volume and custom orders welcome — with full engineering attention, not a minimum-quantity brush-off
Designed and manufactured in the USA

Engineering control systems since 1997 • UL508A • NEMA 1 / 12 / 3R / 4X • Full documentation packages • Made in USA

When the Spec Says “Figure It Out”

Most control panel problems don’t start on the shop floor. They start when a set of incomplete requirements gets handed to a supplier who builds exactly what’s on the drawing — and nothing the drawing forgot. The gaps show up later: at installation, at commissioning, or the first time the panel sees real load in the field.

If you’ve managed a control panel build before, you already know the failure modes:

A supplier builds to the print, but never asks the questions the print doesn’t answer — so the panel works on the bench and fights you on site.
A missing certification or documentation package stalls approval and pushes your schedule.
An off-the-shelf enclosure that was never rated for your environment turns into a recurring maintenance and downtime problem.
Your order is “too small” for the big shops, so it sits at the back of the queue with no engineering attention.

A custom electrical control panel should reduce that risk — not add to it.

What We Build

ACS designs and manufactures custom electrical control panels across utility, industrial, and mining applications. Every build is engineered to your specification and tested before it ships.

Testing	Point-to-point verification, functional testing, and a complete documentation package
Typical Lead Time	10–16 weeks from consult to delivery & install
Volume	Low-volume, one-off, and custom orders welcome

Why ACS

Real Engineering — Not Build-to-Drawing

Most panel shops assemble to a print. ACS is an engineering-led manufacturer: we review your specification, flag what’s missing, and design the panel to work as installed — not just as drawn. That’s the difference between a panel that passes on the bench and one that performs in the field.

We ask the questions your spec doesn’t cover

Integrated electrical engineering review on every build means gaps get caught before they become field problems, rework, or downtime.

Compliance discipline, documented

Full CDRLs, submittals, and test documentation are part of the build — not an upcharge or an afterthought. The documentation discipline we apply to marine and defense programs comes standard on your commercial panel.

Built for the environment it runs in

Panels engineered for continuous duty in dust, vibration, moisture, and temperature extremes — so you reduce unplanned downtime and the ongoing maintenance burden.

Made in the USA, responsive on custom work

Lower overhead and a shorter chain of command than the large primes, which means custom and low-volume orders get real engineering attention and a straight answer on lead time.

Built For

Utility substations, switchyards, and grid infrastructure
Industrial and manufacturing plants
Mining and aggregate operations
Water and wastewater facilities
Outdoor, corrosive, and high-vibration environments

From Specification to Commissioning

A control panel project shouldn’t feel like a sales funnel. Here’s how a build actually goes:

Initial technical discovery. We talk through the application, environment, and constraints — engineer to engineer.
Requirements clarification & collaboration. We identify what the spec covers, what it doesn’t, and how to close the gaps.
Solution development & formal proposal. You get a clear design approach, scope, and realistic lead time.
Support through approval, installation & commissioning. We stay engaged through documentation, install, and startup — including revisions.

Building control and mechanical systems since 1997.

U.S. manufacturer and systems integrator with integrated electrical engineering on every build. Experience spans utility, industrial, mining, and marine/defense control systems — the same engineering and documentation discipline applied to your commercial panel.
