PEC

What PEC does

Process Electronics Corporation (PEC) is a privately held US manufacturer of DC power conversion equipment (rectifiers) for industrial applications, primarily metal finishing and electroplating. Founded in 1984 in Roseville, Michigan as a subsidiary of OMI International Corporation — and relocated to Gastonia and later Mt. Holly, North Carolina after 1988 — the company holds exclusive US manufacturing, sales, and marketing rights for the UDYLITE brand, which originated in 1919. PEC operates from a single facility at 100 Brickyard Road, Mt. Holly, NC, with 1-10 employees.

The product portfolio consists of five DC power converter lines: SASSC (closed-loop liquid-cooled, 500-12,000A), MACC (microprocessor-based air-cooled, 500-12,000A), MARC-A (modular switch-mode, 500-3000A with RS-485), Miniverter (single-phase bench-type, 25-300A), and PC-10 (compact bench-type, 0-10A). Underlying technologies include SCR control, microprocessor-based controls with proprietary short-circuit protection, switch-mode power supply architectures, and a patented two-stage liquid cooling system with a patented peak current limit circuit. All major assemblies, including transformer coils (aluminum and copper), are wound and built in-house. The company has shipped more than 50,000 units globally over 55 years.

Revenue is generated through hardware sales of complete power conversion systems, spare parts (semiconductors, control boards, plumbing components, analog meters), a 34-point preventative maintenance program, field service and emergency repair, and RMA inspection/testing services ($50/board and $250/rectifier, waived if repaired). Pricing is quote-based and not publicly disclosed. The go-to-market combines direct factory sales staffed by factory-trained personnel with local PEC equipment distributors, targeting metal finishing facilities, manufacturing quality control departments, and laboratory/light-duty applications globally. The company is family-owned following the 1996 death of founder George B. Berry, with Carolyn Berry continuing to oversee operations.

Core offering

Process Electronics Corporation (PEC) designs, manufactures, and services UDYLITE-brand DC power conversion equipment (rectifiers) for industrial applications. The portfolio spans closed-loop liquid-cooled converters (SASSC), microprocessor-controlled air-cooled converters (MACC), modular switch mode power supplies (MARC-A), and compact bench-type units (Miniverter, PC-10), with outputs ranging from 0-10 amperes up to 12,000 amperes. Supporting the hardware, PEC sells replacement parts and provides field service, preventative maintenance, inspection/testing, and repair for both PEC/Udylite and competitor equipment globally.

Product overview

Process Electronics Corporation (PEC) offers a portfolio of power conversion equipment under the UDYLITE brand for industrial applications. The core product lineup consists of five specialized DC power converters: SASSC (closed-loop liquid-cooled), MACC (microprocessor-controlled air-cooled), MARC-A (modular switch mode), Miniverter (single-phase bench-type), and PC-10 (compact bench-type dual range). These rectifiers serve surface finishing applications including electroplating, anodizing, electropainting, and galvanizing. Supporting the product line, PEC provides spare parts (semiconductors, boards, plumbing components, voltmeters, ammeters), a 34-point preventative maintenance program, field service with unlimited telephone support, and RMA services. The company designs and manufactures all products in-house at their North Carolina facility.
