Electrosport Voltage regulatorRef : ELS00157A / 1077888

Manufacturer Ref: ESR025 — Brand: ELECTROSPORT. Replaces the internal regulator of Nippon Denso alternators found on a wide range of roadsters and sportbikes (some Suzuki GSX-R / Bandit, Yamaha FJ, Kawasaki Ninja). Designed to manage the charging system and protect the battery and onboard electronics, this rectifier-regulator is intended for demanding riders looking for a reliable and durable replacement.

Compared to the original module, this regulator features improved thermal dissipation capacity and includes a thermal overload protection circuit. This device cuts off the regulator in the event of a short circuit in the alternator rotor, a common issue that can damage the charging system.

• Key Functions: charge management, improved thermal dissipation, thermal overload protection.
• Applications: suitable for Nippon Denso alternators used on several roadster and sport-touring models.
