Balmar MC624S Max Charge 24V Multi-Stage Voltage Regulator

The Balmar MC624S is a microprocessor-controlled multi-stage voltage regulator designed for high-output 24-volt alternators and P-type alternators with external regulation. This intelligent charging regulator delivers precision control to optimize battery charging performance and extend battery life across marine, RV, and powersports applications.

Key Features:

• 24-volt multi-stage programmable voltage regulation
• User-selectable battery programs for 7 different battery technologies including standard flooded, deep cycle flooded, AGM, spiral wound AGM, gel, and LiFePO4 batteries
• Digital LED display shows real-time voltage, charging stage, battery temperature, and diagnostic codes
• Advanced belt load management system allows control of maximum alternator output to prevent belt slip
• Compatible with optional MC-TS-A and MC-TS-B temperature sensors for automatic temperature compensation and over-temperature protection
• Magnetic reed switch programming interface for easy configuration
• Amp manager feature limits field drive output to protect batteries with specific C-rate requirements
• Small engine mode and dual alternator capability with optional Centerfielder II accessory
• Compact dimensions: 4.8" x 3.2" x 1.5"

The MC624S features multi-stage charging with distinct bulk, absorption, and float stages that automatically adjust based on battery state and temperature. The regulator monitors system voltage and can display advisory codes to alert users of potential issues. This model is supplied without a wiring harness (harness available separately as MC-624-H). Ideal for upgrading marine charging systems or replacing factory alternator regulators with an advanced external regulation solution.
