Balmar 621VUP70SV 6-Series 70 Amp Alternator Kit with ARS-5 Regulator

The Balmar 621VUP70SV is a complete 6-Series alternator charging kit designed to deliver high-output performance in a compact, small-case package for marine applications. This 70-amp, 12-volt system features Balmar's patented Smart Ready Technology, providing faster and safer charging for battery types ranging from standard flooded to AGM technologies.

Complete Charging Kit Includes:

• 70-amp, 12-volt small case alternator with single 1/2" pulley
• ARS-5 multi-stage voltage regulator
• Battery and alternator temperature sensors
• Wiring harness and mounting hardware

Key Features:

• Dual internal cooling fans for improved heat dissipation
• Fixed voltage internal regulation with external regulator capability
• Dedicated isolated ground terminal for improved system ground and noise reduction
• Multi-position tensioning crown for easy belt adjustment
• Durable white powder-coat finish for marine environments
• Single foot (spool) mount configuration with 1" or 2" mounting options
• Lamp circuit for charge indication

The Smart Ready internal regulator can function as a standalone system for smaller battery loads and frequent engine operation, or seamlessly integrate with the included ARS-5 external voltage regulator for larger deep-cycle battery banks and less frequent duty cycles common in sailing applications. This VUP model is compatible with engines using single foot mounting, including many Mercruiser, Volvo Penta, Pleasurecraft, Crusader, Westerbeke, Yanmar 6LP, and other marine diesel and gas engines equipped with Delco or Motorola-style alternators.
