Control Panel FAQs: Lead Time, Certification, Testing

Uni Regal builds custom UL 508A control panels, electrical enclosures, and industrial UPS systems for OEMs, system integrators, and EPCs worldwide.

Custom UL 508A control panels manufactured
Below are the questions OEMs, system integrators, and EPCs ask us most before placing an order—covering lead time, UL 508A certification, FAT testing, enclosure ratings, brands we integrate, and international shipping from our Foshan, China, factory.

Frequently Asked Questions

Do you build UL 508A certified control panels?

Yes. We design and build custom control panels to UL 508A standards and work with NRTL partners for listing and field-labeling. For projects that only require self-declaration, we supply the full construction file, torque records, and test reports so your panel passes local inspection.



What is your typical lead time for a custom control panel?

Standard custom panels ship in 2–4 weeks; more complex builds with special enclosures or multiple PLC brands run 4–8 weeks. Every panel goes through FAT before shipment, so the lead time you are quoted already includes testing—not just assembly.

Can you build panels around Mitsubishi, Siemens, ABB, or Allen-Bradley?

Not really. But we could apply for all of the components from authorized channels. So that we integrate Mitsubishi, Siemens, ABB, Allen-Bradley, Yaskawa, Omron, and Schneider components, and we are experienced with mixed-brand systems where a project specifies more than one PLC or drive family.

Do you provide Factory Acceptance Testing (FAT) before shipment?

Yes. Our FAT checklist covers wiring verification against the schematic, I/O functional testing, safety-circuit confirmation, and a full power-up run. You receive a signed FAT report and photos, so commissioning on-site starts from a known-good panel.



What IP and NEMA ratings do your enclosures support?

We build enclosures from IP54 up to IP66 and NEMA 4 / 4X in stainless steel or powder-coated mild steel. For outdoor and coastal sites, we offer 316 stainless and anti-corrosion treatment to resist salt spray and UV.

Do you ship internationally and handle export documentation?

Yes. We export worldwide from Foshan, China, with FOB or CIF terms, and supply CE/UL documentation, HS codes, packing lists, and commercial invoices. We regularly ship to North America, Europe, the Middle East, and Southeast Asia.

What do you need from me to prepare a quote?

Send us the electrical schematic or I/O list, your preferred component brands, target quantity, operating environment (indoor/outdoor, temperature, dust/water exposure), and any certification requirement. If you only have a rough idea, we can help turn a one-line spec into a buildable panel.

Will I get wiring diagrams and full documentation?

Yes. Every panel ships with schematics, a bill of materials, the I/O list, setpoint records, and a user manual. Documentation is provided in editable and PDF formats so your maintenance team can service the panel after handover.

What is your minimum order quantity (MOQ)?

We accept single-unit custom orders—there is no minimum for bespoke panels. Volume builds get better per-unit pricing, but prototypes and one-off replacements are a normal part of our work.

Do you manufacture industrial UPS systems?

Yes. We build industrial UPS systems for CNC machines, data rooms, and harsh-environment control cabinets, with options for extended battery runtime and wide input-voltage tolerance. UPS can be integrated inside the same enclosure as your control panel.

Can you build panels for water treatment, oil & gas, HVAC, or packaging?

Yes. We deliver panels for water treatment, oil & gas, HVAC, packaging, and material-handling lines, with enclosures and component choices matched to each environment. Tell us the duty cycle, and we'll design around it rather than using a generic box.

What certifications does Uni Regal hold?

We run an ISO 9001 quality system and build to CE and UL 508A requirements. Component-level certificates (UL, CE, RoHS) are supplied per project, and we can support third-party inspection when your tender requires it.

Still have a question we didn't cover?

Email Natalie at info@uniregal.com with your drawing or spec, and we'll come back with a quote and a buildable plan—usually within 1–2 business days.
