Pro Chaser DC-DC Converter for Golf Carts & RVs — 48V/36V to 12V 30A Step-Down, Ventilated Aluminum

The Pro Chaser DC-DC converter reduces 36V or 48V golf-cart/RV battery packs to a steady 12V/30A output for lights, radios, and accessories.

Designed for utility vehicles and recreational rigs, this compact 360 W step-down regulator provides a reliable 12V supply from six-battery 36V (6×6V) or 48V (6×8V) systems. It’s housed in a ventilated aluminum shell, ships with a color-coded wiring harness and a full-color manual, and includes built-in overload protection and factory burn-in testing to help ensure consistent operation in typical vehicle environments.

How do I wire the Pro Chaser converter safely?

Wiring is streamlined with color-coded leads and a single-line wiring diagram in the included manual. Match each harness wire to its labeled terminal and torque all connections to the specified range to minimize arcing and voltage loss.

• Thin black → battery negative (–)
• Thick red → battery positive (+)
• Thick black → accessory negative (–)
• Yellow → accessory positive (+)
• Thin red → key-switch/switched 12V terminal

What electrical limits and protections should I observe?

The unit is rated for 360 W continuous output (12 V × 30 A) with short surge tolerance up to 400 W. It includes an overload protector that trips when current is too high; after a trip, remove the load and wait about 60 seconds before attempting restart.

• Maximum continuous: 360 W (30 A at 12 V)
• Peak surge tolerance: ≤ 400 W
• Automatic trip on overload; manual reset by removing load
• Factory-tested with 1-hour full-load burn-in and surge simulation

Where should I mount the converter and what environmental limits apply?

Install the converter in a dry, ventilated location under the vehicle or inside a compartment that avoids direct water spray and excessive heat. Maintain free airflow around the vents and keep the unit within the specified operating temperature and humidity range for reliable performance.

• Operating temperature: 0 °C to 50 °C
• Maximum relative humidity: ≤ 85%
• Secure under-vehicle wiring to prevent chafing and strain
• Tighten terminals to 4–6 N·m for secure electrical contact

What comes in the box and how does the harness simplify installation?

The package includes the Pro Chaser DC-DC converter, a matched color-coded harness with butt connectors, and a full-color manual with a step-by-step wiring illustration. The harness reduces guesswork during installation and speeds up hookup for common 36V and 48V golf-cart/RV battery layouts.

• Color-coded harness for direct wire matching
• Butt-connectors supplied for secure splicing where needed
• Full-color manual with single-line wiring diagram and final-image step-by-step guide
• Aluminum-cast shell with venting for heat dissipation

Who is this for: The Pro Chaser DC-DC 48V/36V to 12V converter is intended for golf cart owners, RV enthusiasts, fleet technicians, and anyone who needs a dependable 12V source from a legacy multi-battery pack. It suits users who prioritize a compact, ventilated regulator with clear wiring, factory testing, and basic overload safeguards — ideal for powering lights, radios, solar-charge controllers, and other 12V accessories when running from 36V or 48V systems.
