Parallax Power Supply

What Parallax Power Supply does

Parallax Power Supply is a privately held American manufacturer of electrical power conversion and distribution systems for the recreational vehicle (RV) industry, operating under the legal entity Parallax Group Inc. and headquartered at 600 Broadway St., Anderson, Indiana. The company was founded in 1970 with heritage traceable to Phillips, BW Manufacturing, and MagneTek, positioning it as one of the original developers of solid-state three-current stage converter/charger technology for RV applications. Its core product portfolio spans Deckmount Converters (4400 and 5400 Series, 35-90 Amp), Power Centers (5300, 6730D, 7155, and 8300 Series), Transfer Switches, Circuit Breakers, Fuse Panels, Distribution Panels, and Outdoor Power Outlets, all manufactured in North America with steel enclosures and certified by Intertek (ETL/NRTL). The company's primary technological differentiator is TempAssure™, a patented temperature-compensated charging system that adjusts battery voltage in real-time based on temperature readings. Complementary offerings include wireless TempAssure upgrade kits, a lithium battery charging module, and a Replacement Unit (RU) Series that provides direct drop-in replacements for legacy MagneTek and B-W Manufacturing systems.

Parallax serves two primary customer segments: RV original equipment manufacturers (OEMs) building new recreational vehicles, and the aftermarket through an exclusive Certified Dealership Program with hundreds of dealers across the United States and Canada. The company generates revenue through direct hardware sales of electrical components, with a standard 2-year limited warranty and an optional $50 extended warranty add-on. Distribution is channel-mediated: the company does not sell directly to end consumers but routes both OEM and aftermarket sales through its certified dealer network, offering drop-ship pricing, product training, and customer referrals as dealer incentives. Technical support is delivered via a toll-free phone line, email, and comprehensive online documentation including archived technical resources for legacy products.

The business model is fundamentally a specialty hardware manufacturer operating in a niche vertical with limited geographic reach (North America only). Revenue is concentrated in RV electrical components with no disclosed diversification into adjacent verticals or software/service revenue streams. The company maintains a lean headcount of 11-50 employees and operates from a single manufacturing location, with no disclosed funding rounds, M&A activity, or external investment.

Direct peers

• Samlex America: Samlex America manufactures DC power supplies, battery chargers, and inverters for mobile, marine, and RV markets, with product categories that overlap Parallax's converter/charger, transfer switch, and outdoor power outlet offerings.
• WFCO Technologies: WFCO is a direct competitor to Parallax in RV power converters, power centers, and distribution panels, selling through the same OEM and dealer channels across North America. Its Wildcat and RVC inverter/charger and converter lines overlap head-to-head with Parallax's 4400, 5400, and 8300 series.
• Xantrex (Schneider Electric): Xantrex, now part of Schneider Electric, manufactures RV and mobile inverter/chargers, transfer switches, and energy management systems that compete with Parallax's converter, ATS, and energy-management product lines at the OEM level.
• IOTA Engineering: IOTA Engineering makes RV battery chargers, converters, and power supplies, including DLS series converters that compete directly with Parallax's deckmount and power-center lines at OEM and aftermarket.
• Progressive Dynamics: Progressive Dynamics manufactures RV converters, power centers, and distribution panels with Inteli-Power and similar multistage charging technology, competing directly against Parallax's three-current stage and TempAssure™ products in both OEM fitment and aftermarket replacement.
• Magnum Energy (Sensata): Magnum Energy, now under Sensata, produces RV inverter/chargers and energy management products targeting the same OEM and premium aftermarket customers as Parallax's higher-amperage 5400 and 8300 series products.

Broad incumbents

• Furrion: Furrion is a broad RV electronics and appliance incumbent supplying OEMs with power, audiovisual, and energy management systems, creating a one-stop alternative to Parallax for OEMs that prefer bundled electrical solutions.
• Atwood (Airxcel): Airxcel is a broad RV products incumbent that owns multiple RV component brands, and its acquisition of WFCO places it directly against Parallax in power conversion while also bundling adjacent HVAC, appliances, and accessories that OEMs may prefer as single-source suppliers.

Emerging players

• Victron Energy: Victron Energy provides inverters, chargers, and battery management systems popular in premium and off-grid RV applications, including lithium compatibility. It overlaps with Parallax on converter/charger functionality but competes more on software-defined, inverter-integrated systems.
• Go Power!: Go Power! specializes in RV solar, inverter, and lithium-compatible charging systems. Its overlap with Parallax is partial, focused on converter/charger and lithium-ready products, making it an emerging competitor in the lithium RV power segment.
