Control Panels
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.
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 Foshan, China.
Frequently Asked Questions
Can you supply UL 508A listed control panels?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?
It depends on what we are supplying, and we quote each scope separately. Empty enclosures and cabinets ship in about 15 days, from 5 units. Complete custom panels — engineered, built and tested to your drawings and BOM — run 35–40 days, and we build them from 1 unit. Component orders (PLC, VFD, HMI and spare parts) ship in 3–5 days when stock is available. The 35–40 day figure already includes FAT, so you are quoted a tested panel, not just an assembled one.
Can you build panels around Mitsubishi, Siemens, ABB, or Allen-Bradley?
Yes. We source all of the components from authorized channels and 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)?
It differs by supply scope, so there is no single number. Complete custom panels start from 1 unit — prototypes and one-off replacements are routine work for us. Empty enclosures and cabinets start from 5 units with roughly 15 days to ship, because the tooling and finishing line only runs economically at that quantity. For components there is no MOQ; we ship what is in stock in 3–5 days. Volume improves per-unit pricing at each of these tiers, but it is never a condition of quoting.
Can you supply industrial UPS systems?
Yes. We source and integrate 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 quality standards and certifications do you work to?
We build to CE and UL 508A requirements under a quality-managed process, and UL 508A listing is routed through NRTL partners with the file number verifiable in writing. 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.
