Open a distributor accountSpecialized Distributor of Advanced Power Electronics
Advanced power devices and components, sourced and supported in the United States.
APDC is a technical distributor, not a parts warehouse. We select advanced power electronics, verify their documentation, quote them from the U.S., and coordinate delivery — whether you need five contactors next week or a solid-state transformer for a datacenter build.

Start where you fit
We sell wholesale to the trade. The fastest route depends on who you are — pick the one that describes you and you will land on the right form, with the right questions already asked.
Power design firms & specifiers
Designing our components into your product or system? Ask for full technical specifications, application support, evaluation units and design-in pricing.
Get technical specsDatacenters, EPCs & utilities
For SST, UPS, transfer switch and large energy equipment, we scope the application with you and the manufacturer, then coordinate production, inspection and delivery to site.
Discuss a projectContractors & installers
Please work through your local electrical supply store. They can order APDC products for you at trade terms. If your store does not carry us yet, send us their details and we will reach out.
Refer your local storeWhat we supply
Nine departments spanning the whole conversion chain. Each product page carries full electrical and environmental ratings, certification status, lead time, warranty and minimum order quantity.
AC/DC and DC/DC Converters
Isolated and non-isolated modules, DIN-rail supplies and bidirectional converters for storage, test and industrial DC systems.
Inverters and Rectifiers
Grid-tied and central inverters, telecom rectifier shelves and medium-voltage rectifier lineups for industrial DC process loads.
UPS and Power Distribution
Online UPS from 20 kVA to multi-megawatt modular systems, metered and switched rack PDUs, and busway tap-off units.
Solid-State Transformers
SST lineups that take medium voltage directly to a regulated DC bus for AI datacenters, charging plazas and DC microgrids.
High-Speed Transfer Switches
Static and high-speed transfer switches for dual-source distribution, from 400 A rack-level units to 4000 A switchboards.
Contactors and Switching Devices
IEC contactors, sealed high-voltage DC contactors and solid-state relays — held in U.S. stock for fast replacement.
EV-Charging Modules
Liquid- and air-cooled charging power modules, EVSE controllers and OCPP-capable control boards for charger builders.
Sensors and Control Components
Hall-effect and Rogowski current sensors, isolated voltage transducers, SiC gate drivers and thermal monitoring modules.
Portable Energy Equipment
Portable energy storage, mobile power carts and inverter generators for field service, emergency response and job sites.
Three ways to buy
Power electronics do not all buy the same way. A contactor has a price; a solid-state transformer has a project. Every product in our catalog is tagged with one of these three routes so you know what happens when you click.
Published price, order online
Standard modules, sensors, contactors and replacement parts held in U.S. inventory. Price and minimum order quantity are shown on the page; add them to a request and we confirm the same day.
See stocked products →Configure and request a quote
Converters, transfer switches, PDUs and charging modules where voltage, cooling, connectors and firmware change the build. Tell us the configuration and we return a firm price and lead time.
See configurable products →Discuss your project
Solid-state transformers, large UPS, medium-voltage rectifiers and high-speed transfer switches. We scope the application with you and the manufacturer before any price is issued.
See project equipment →Why buy through a specialist
A broad-line catalog will sell you a part number. A specialized distributor makes sure the part is the right one, that its documentation survives an inspection, and that somebody in your time zone answers when the schedule moves.
-
Carefully selected products
A short, deliberate line we can actually stand behind, not a search index.
-
Technical product knowledge
Ratings, derating curves and topology trade-offs discussed before you commit.
-
Certification documentation
Listing and compliance paperwork gathered per model, for your AHJ and your file.
-
Product-selection assistance
Send the load profile and constraints; we come back with candidates and reasons.
-
Access to specialized manufacturers
Including overseas builders that are difficult to reach and qualify directly.
-
U.S. quoting and purchasing
One domestic PO, one domestic invoice, and importer-of-record handled for you.
-
Project coordination
Production tracking, inspection, staging and delivery for datacenters, EPCs and utilities.
-
Customization and integration
Connector sets, firmware profiles, enclosures and kitting arranged with the factory.
How an engineered order moves
For configured and project equipment, this is the path from your first message to equipment on site. You get a named contact at step one and the same contact at step seven.

The manufacturer builds to the released configuration. We track and report milestones.
-
05
Inspection
Incoming or factory inspection against the agreed test plan, with witness testing where required.
-
06
Shipment or staging
Direct shipment from the factory, or staging through a U.S. logistics partner for phased delivery.
-
07
Delivery and support
Delivery to site, documentation package handover, and warranty support through APDC.

A note on certification
Certification is stated per model, never per company. We describe a product as UL Listed or UL Recognized only when that exact model number has been verified in the certifying body's directory, and we will send you the documentation to confirm it. APDC does not represent itself or its catalog as a whole as certified. Where a listing is pending, project-specific or jurisdiction-dependent, the product page says so plainly.
Request certification documentation →Tell us what you are building.
Send a part number, a load profile or a single-line diagram. You will hear back from a person who can talk about the electrical detail, not a ticket queue.
