15A BLACK W/P HEAVY CONVERTOR

he 15A Black Waterproof Heavy Converter is a high-efficiency DC-DC step-down power module designed to convert high-voltage main traction battery power (48V to 72V DC) into a safe, regulated 12V output.

Built specifically for electric scooters, e-bikes, and e-rickshaws, this converter powers critical 12V auxiliary electronics—including headlights, tail indicators, horns, turn signals, and digital dashboard display panels—without draining individual battery cells unevenly.

Equipped with an integrated light fuse for instant overcurrent protection, the converter features a heavy-duty weather-sealed housing engineered to withstand road splashes, vibration, heat, and rain.

Key Features

Wide Input Voltage Range: Seamlessly steps down input voltages from 48V to 72V DC, making it universally compatible with most electric two-wheeler and three-wheeler battery setups.

15A High-Current Output: Delivers a stable 12V DC output up to 15A (120W max), providing ample power to run multiple auxiliary accessories simultaneously.

Integrated Light Fuse Protection: Includes a built-in fuse system that instantly cuts power during current surges or short circuits, protecting both the converter and connected 12V accessories.

Heavy-Duty & Waterproof (IP-Rated): Encased in a rugged black housing designed to resist water ingress, dust, and environmental wear during outdoor riding.

High Conversion Efficiency: Operates at ~90% power conversion efficiency to reduce energy loss and prevent unwanted heat buildup.

Compact Plug-and-Play Footprint: Slim, low-profile body fits easily inside scooter battery bays or front head cowls without added bulk.

1.Safety & Power Isolation:

Turn off the main battery power switch and disconnect the battery pack from the converter harness before touching any electrical leads to prevent accidental short circuits or spark discharge.

2.Mount the Converter Unit:

Securely attach the converter housing to a clean, flat surface on the scooter frame (such as the main body frame or cowl panel) using mounting screws or zip-ties. Ensure it is placed in an area with adequate airflow for heat dissipation.

3.Connect High-Voltage DC Input (48V–72V):

Connect the high-voltage input leads from the converter harness directly to the main battery power supply/switched terminal line, making sure to match polarity:Red Wire (+): Positive battery line (switched via key ignition).Black Wire (-): Negative battery ground line.

4.Connect 12V Auxiliary Output Lines:

Attach the 12V step-down output wires to your vehicle's 12V accessory wiring harness (powering headlights, tail lights, horn, turn signals, or dashboard display panel):Yellow/Red Wire (+): 12V Positive output feed to accessories.Black Wire (-): Common ground negative return line.

5.Test & Confirm Power Output:

Reconnect the main battery terminals, switch on the ignition key, and toggle individual 12V accessories (light switch, horn button) to verify power supply stability.

Wipe the converter casing regularly with a dry or slightly damp cloth to keep dirt, mud, and road debris from clogging the surface. Periodically inspect the wiring harness for frayed insulation, exposed leads, or loose terminals, and ensure the built-in light fuse housing remains tightly sealed against moisture ingress.
