REC2412-NG Series Reducer / Equalizer / Charger Technical and Customer Service Guide

Model Overview

The REC2412-NG series, including models REC2412-20NG and REC2412-30NG, introduces a new generation topology that enhances size efficiency and output power. These models serve as Reducers, Chargers, and Equalizers, encapsulated in a compact, weather-resistant, and vibration-resistant package.

Key Features

Dimensions: 160mm x 70mm x 30mm
Encapsulation: Fully encapsulated for improved resistance to vibration and humidity.
Efficiency: Approximately 95%, ensuring cooler operation and extended lifespan.
Standby Drain: Below 0.005A.
Modes: Selectable as a multi-stage charger, equalizer, or dual fixed voltage reducer.
Battery Compatibility: Supports sealed LA, vented LA (60AH-300AH), and Lithium batteries (40AH to 300AH).
Protections: Built-in automatic current limit, over-temperature, and over-voltage protections.
Remote Status Indicator: LED indicator for operational visibility.

Installation and Safety Precautions

Connection Sequence: Ground → Selection wires (if used) → Input → Output → Ignition. Input and ground wires should support at least 20A (REC2412-30NG) or 10A (REC2412-20NG), and output should support at least 40A.
Wire Insulation: Insulate and secure unused wires. Ensure correct polarity to avoid damage.
Battery Compatibility: Verify unit compatibility with your specific battery type.
Installation Location: Avoid heat sources and ensure good ventilation.
Water and Contamination Protection: Protect wiring and unit from water, oil, or grease.
Flammable Materials: Install away from flammable substances.
Battery Charging Safety: Avoid naked flames near batteries and ensure a BMS is installed with Lithium batteries.
