Product Details

The Balmar 621-VUP-MC-120-DV is a complete 120-amp, 12-volt marine alternator charging kit built around Balmar's best-selling 6-Series high-output alternator platform. Designed for VUP (Volvo/Universal/Perkins-style) single-foot spindle-mount engines, this factory-matched package eliminates the guesswork of building a custom charging system by pairing a high-output alternator with a smart multi-stage voltage regulator and all necessary sensors and hardware.

What's Included:

  • 621-120-DV Alternator – 120A, 12V, isolated ground, spindle-mount (single foot), with Dual Deep Vee pulley
  • MC-614 Max Charge Multi-Stage Voltage Regulator – programmable, microprocessor-controlled external regulator
  • MC-TS-A Alternator Temperature Sensor
  • MC-TS-B Battery Temperature Sensor
  • Mounting hardware

Key Features:

  • 120 Amps / 12 Volts output – ideal for vessels with moderate to heavy house battery loads
  • Dual Deep Vee (DV) Pulley – compatible with standard 1/2" dual belt drive systems
  • Dual Internal Cooling Fans with high-airflow frame for thermal management
  • Smart Ready® Technology – allows operation with or without external regulation, with built-in internal regulator redundancy
  • Isolated Ground design for clean electrical performance in marine environments
  • 1" Motorola-Style Mounting – typical for Westerbeke, Lehman, Hino, and Pathfinder engines
  • 2" Delco-Style Mounting – typical for Volvo Penta (gas & diesel), Nanni, John Deere, Perkins, Mercruiser, Pleasurecraft, Crusader, Indmar, Marine Power, and other GM-based engines
  • Maximum RPM: 12,000
  • 4.0 HP power take-off
  • USCG Title 33, ISO, SAE, and CE compliant

The included MC-614 Max Charge regulator is a multi-stage, microprocessor-controlled voltage regulator that monitors and adjusts charging based on battery temperature, charge level, and belt load, delivering an optimized charge profile for flooded, gel, AGM, and lithium battery banks. The dual temperature sensors (alternator and battery) ensure the system protects both the alternator and the battery throughout the charge cycle.

The 621-VUP-MC-120-DV is the smart choice for cruising boaters and live-aboards looking to upgrade their vessel's charging capability with a complete, pre-matched system backed by Balmar's reputation for marine-grade quality.
