Rmstator RMS022-106799 Series Machined Aluminum Voltage Regulator Rectifier 50 Amp Universal

The Rmstator RMS022-106799 is a Series Machined Aluminum 50-Amp Voltage Regulator Rectifier engineered as a high-performance upgrade over OEM and standard shunt-type regulators. Featuring Rmstator's advanced Series voltage regulation technology, this unit delivers improved charging system reliability, more precise voltage control, and dramatically lower operating temperatures compared to conventional designs.

How Series Technology Works:

Unlike traditional shunt regulators that control battery voltage by grounding stator coils and dissipating excess energy as heat, the Series regulator works by intermittently disconnecting stator coils from the regulator electronics. This limits current flow through the unit and to the battery more efficiently, resulting in lower regulator and stator temperatures, more accurate voltage regulation, and extended component life.

Key Features:

• 50-Amp / 500W maximum charging current for robust, high-demand applications
• Machined billet aluminum housing dissipates heat 33% more effectively than standard molded casings
• Series regulation technology runs significantly cooler than shunt and MOSFET-type regulators, including OEM units
• Power only flows through electrical components when the battery is actively charging, reducing load on the stator and extending its service life
• Minimum charging voltage: 14.5V ± 0.5V
• Open circuit voltage: less than 15V
• Operating temperature range: -20°C to 85°C (-4°F to 185°F)
• 2-plug, 5-pin connector configuration
• Plug-and-play installation — no assembly required
• Each unit is tested prior to shipment
• Includes opposite connector (main harness side), as factory connectors are a common source of recurring electrical problems
