VDBC1224-20-NG-2 Booster Battery Charger / Doubler Technical and Customer Service Guide
Overview
The VDBC1224-20-NG-2 is part of the Next Generation (NG) series, offering advanced technology in a compact design for efficient power conversion and battery charging. This unit serves dual purposes as a 3-Stage 24V Battery Charger and a Voltage Doubler, designed for 12VDC to 24VDC conversion with a peak output of 20A. It is built to withstand weather, dust, and vibration, making it suitable for a wide range of applications.
Key Features
- Dual Functionality: Operates as a 24V Battery Charger or Voltage Doubler.
- Selectable Output Voltages: Supports various battery types including Lithium (29.6V/27.6V), Sealed Lead Acid (28.4V/27V), Vented Lead Acid (29.2V/27V), and Doubler mode (25V/27V/28V).
- Protection Mechanisms: Features over-current and temperature protections, precise under-voltage protection without the need for an external isolator, and latched overload protection.
- Efficiency and Standby: Boasts a high efficiency (>95%) and very low standby current (<3mA).
- Remote LED Indication: For monitoring battery charge status.
Installation Instructions
- Preparation: Ensure the battery supply is disconnected before installation.
- Connection Sequence: Follow the specific order for connections - Ground (BLACK), Output (BROWN), Input (RED), LED (GREEN), Chemistry/Output Selection (Orange), ON/OFF (Blue), and Mode Select (WHITE). Connect the BLACK and BROWN wires directly to the 12V input battery.
- Mounting Considerations: Avoid pressure washing or mounting in areas prone to submersion. Keep away from fuel lines, external heat sources (e.g., exhaust systems), and battery locations.
- Ventilation: Choose a well-ventilated installation spot to allow free air circulation around the unit.
- Protection from Contaminants: Install the unit in a location protected from oil, grease, dust, flammable fumes, liquids, or materials.
Wiring Diagrams
- For Doubler Setup: Includes connections for 27V, 28V, and 25V outputs with specific instructions for the Chemistry Selection in Doubler Mode.
- For Charger Setup: Details the connections for Vented Lead Acid, Lithium, and Sealed Lead Acid batteries with corresponding fuse ratings (Main Fuse: 30A, Battery Fuse: 50A).
Safety and Precautions
- Isolation of Unused Wires: Ensure that any floating or unused wires are properly isolated or taped up to prevent accidental connections.
- Fuse Ratings: Main Fuse should be 30A, and the Battery Fuse should be 50A for both setups.
Warranty and Support
- Warranty Period: 2 years from the date of original purchase, covering defects in material and workmanship under normal use and service.
- Australian Consumer Law: Products come with guarantees that cannot be excluded, including entitlements to replacements, refunds for major failures, and compensation for any other reasonably foreseeable loss or damage.
