Mecc Alte | Ducati Energia 40µF Run Capacitor | P/N 416.17.27.60 | 9910303140

Ducati Energia 40µF Run Capacitor, P/N 416.17.27.60 | 9910303140 for Single-Phase Alternators, 475V~, FASTON Terminals, Fits Mecc Alte & Other Self-Excited Generators

• VOLTAGE REGULATION FOR SELF-EXCITED ALTERNATORS: Part# 416.17.27.60 acts as an analog voltage regulator on capacitor-regulated, self-exciting alternators (e.g., Mecc Alte and similar single-phase generator models). It works with the auxiliary winding to store and release electrical energy, keeping output voltage steady while the generator runs. It is a simpler alternative to an electronic AVR on smaller units.

• BUILDS & MAINTAINS EXCITATION: Helps the alternator build up and sustain its magnetic field so it can generate electricity from startup through steady-state operation.

• PRECISE ELECTRICAL SPECS: 40µF capacitance (±5%), rated 475V~ (10,000h, Class B) per EN 60252-1/A1. Suitable for 50-60Hz systems. Body size 45 x 117 mm (D x H).

• BUILT FOR RELIABILITY: Plastic case with UL-94 Class V2 self-extinguishing cover, Safety Class S0, VDE and IMQ approved. FASTON 6.3 mm double-tag terminals, no mounting stud.

• KNOW WHEN TO REPLACE: Signs of a failing capacitor include no power output with the engine running, voltage well under 120V/240V, flickering or surging power, or a bulged or cracked case with resin or oil leakage. Part# 416.17.27.60 is a replacement for units specifying this capacitor.

Manufacturer Part Number: 416.17.27.60 (Ducati Energia, Series 416.17)

A generator capacitor is the voltage-regulation component in capacitor-regulated, self-exciting alternators. It stores and releases electrical energy to keep output voltage stable as the generator runs, working alongside the auxiliary winding to build and maintain the alternator’s magnetic field. On smaller single-phase generator models, this is a cost-effective alternative to a full electronic Automatic Voltage Regulator (AVR).

This Ducati Energia 40µF run capacitor (P/N 416.17.27.60) is manufactured to EN 60252-1/A1 with VDE and IMQ approval, in a self-extinguishing plastic case (UL-94 Class V2). It measures 45 x 117 mm and uses double FASTON 6.3 mm terminals with no mounting stud.

Common failure symptoms this part resolves:

• Generator runs but produces no electrical output
• Voltage far below normal (well under 120V/240V)
• Flickering lights or surging power
• Visible bulging, cracking, or resin/oil leakage from the capacitor case
• VOLTAGE REGULATION: Stabilizes output voltage on capacitor-regulated, self-exciting single-phase alternators (Mecc Alte and similar).
• EXCITATION: Helps the alternator build and maintain its magnetic field from startup through steady operation.
• SPECS: 40µF ±5%, 475V~ (10,000h, Class B), 50-60Hz, per EN 60252-1/A1.
• SIZE & TERMINALS: 45 x 117 mm body, double FASTON 6.3 mm tabs, no mounting stud.
• BUILD & CERTS: Plastic case, UL-94 V2 self-extinguishing cover, Safety Class S0, VDE and IMQ approved.
