Rectifier Regulator, MOSFET 20 Amp (Tri-Spark)

MOSFET voltage rectifier regulator. Suits 2 and 3 wire stators up to 20 amps. Can be used for positive or negative earth.

These voltage regulators use latest MOSFET technology for cool running reliability. Generous 20 amp rating exceeds the requirements of 10 amp, 16 amp and 14.5 amp two and three wire stators commonly used on British bikes.

Heavier wire connections are extra long (60 cm), in two sleeves so you can route the wires and connect them exactly as you wish.

Smaller in size makes fitting possible in tight locations under the seat or behind side covers. Cool running so you can hide it away!

Suitable for use with 2 and 3 wire stators (single and three phase), 10 amp single phase, 16 amp single phase and 14.5 amp three phase. These stators are commonly known as RM21, RM23 and RM24 and used on Triumph, Norton, BSA and other British bikes. It is compatible with any single or three phase permanent magnet 12 volt alternator up to 20 amps.

Whether you are replacing the original equipment plate rectifier and zener diode or upgrading an older regulator, this one will tick all the boxes!

Wiring instructions included and covered by a 2 year warranty.

Size: 80 x 67 x 20 mm
