Universal MOSFET Regulator Rectifier RM30511H - Handles up to 350 Watts

Universal fitment - 75 mm between fixation holes - 7 wires

Part RM30511H is a brand new MOSFET voltage rectifier regulator designed as a universal replacement for traditional OEM diode-style units. It is not tied to one make or model: the mounting holes are 75 mm centre to centre and the unit is supplied with seven wires on a generous 660 mm lead, so it can be adapted to a wide range of charging systems where a 350 watt capable regulator is required. That makes it a practical answer for machines whose original regulator is obsolete, for custom and rebuild projects, and for anyone upgrading away from a repeatedly failing diode unit.

The regulator rectifier converts the alternating current produced by the stator into direct current and then holds that output steady so the battery and the electrical system are neither undercharged nor cooked. The important difference here is the switching technology. MOSFET regulators work with much lower internal resistance than the diode-style shunt regulators fitted as original equipment on most older machines, so far less of the surplus energy is turned into heat inside the unit. Cooler running is the single biggest factor in how long a regulator survives, which is why a MOSFET conversion is such a common fix on models with a history of charging failures.

RMSTATOR build the unit with a higher grade of electric components and an improved heat sink, and describe it as offering improved heat sink and charging capabilities over the original design. Installation is described as plug-and-play and direct fit against the specifications listed below. All shipped products are tested before they leave the factory.

Because this is a universal part rather than a model-specific one, the fit is determined by the physical and electrical specification rather than by a vehicle list. Check the 75 mm hole spacing, the 108 x 84 x 41 mm body size, the seven wire configuration and the 350 watt rating against your machine before ordering, and check the wiring layout of the unit you are replacing.
