Universal 36V–72V 1000W–1500W Dual-Mode Sine Wave BLDC Controller (50A Peak

The Universal 36V-72V 1000W-1500W Controller provides intelligent dual-mode sine wave & square wave operation with up to 50A peak current output. Featuring an upgraded internal weather-sealed terminal panel, this 12-MOSFET controller eliminates exposed power lead splices to prevent rain-induced short circuits on e-bikes, trikes, and electric scooters.

⚠️ Important Wiring & Internal Terminal Notice

UPGRADED WEATHERPROOF TERMINAL HOUSING:

  • Hidden Internal Power & Phase Terminals: Unlike traditional controllers with external flying leads, the heavy-gauge battery and motor phase connections are located inside the rear protective cover. Unscrew the back panel, wire directly to the internal terminal block, and re-seal the cover for maximum IP-rated water resistance.

  • Dual-Mode Auto Fallback: Runs silently in Sine Wave Mode when motor Hall sensors are active. If Hall sensors fail or are disconnected, the controller automatically switches to Square Wave Mode to keep you riding.

🚀 Key High-Performance Features

  • Wide-Voltage Operational Range: Built for 36V, 48V, 60V, and 72V DC systems (accepts 36V to 84V max charging limits).

  • High-Torque 50A Current Output: Drives 1000W to 1500W motors with rapid acceleration and steep hill-climbing power.

  • Auto-Learning Self-Study Harness: Integrated intelligent recognition loop automatically senses motor phase angle and rotation direction.

  • Dual Speedometer Telemetry: Supports both Phase Speedometer (Voltage) and Hall Speedometer display instruments.

  • Complete Multi-Function Harness: Pre-wired for High/Low Brakes, 3-Speed Shift, Single-Wire Reverse, Cruise Control, and Anti-Theft Alarm.

🛠️ Step-by-Step Wiring & Setup Procedure

1
Wire High-Current Main Connections
Open rear cover before connecting battery power
1.Wire High-Current Main Connections:Open rear cover before connecting battery power.

Unscrew the rear panel to access the hidden internal terminals. Wire the Battery Positive (+) and Battery Negative (-) directly, then attach the three Motor Phase Wires (Blue, Green, Yellow). Re-seal the rear cover.
2
Connect Motor Hall Sensors & Throttle
2.Connect Motor Hall Sensors & Throttle:

Plug in the 5-wire Motor Hall Sensor connector. Connect the 3-pin Throttle harness (Red +5V, Black Ground, Green Signal) and the Electric Door Lock / Ignition Wire (must receive battery voltage to power up the controller).
3
Run Auto-Learning Self-Study Cycle
Must be performed within 2 minutes of powering on
3.Run Auto-Learning Self-Study Cycle:Must be performed within 2 minutes of powering on.

  1. Turn on system power while holding the two white Intelligent Recognition Wires together.

  2. The motor wheel will automatically spin forward or backward.

  3. If spinning backward, disconnect the white wires and plug them together again until the wheel spins forward.

  4. Once spinning forward, disconnect the intelligent recognition wires to lock the setting.
4
Attach Auxiliary Function Harnesses
4.Attach Auxiliary Function Harnesses:

Plug in required peripherals: High/Low Brake Cutoffs, 3-Speed Switch, Single-Wire Reverse (ground to any black wire to activate), Speedometer Line, and Cruise Control.

📋 Harness Pinout Index

  1. Motor Hall Sensor: 5-Wire Connector (Red, Black, Yellow, Green, Blue)

  2. 3-Speed Gear Harness: High / Medium / Low Speed Selection

  3. Single-Wire Reverse: Connects to throttle reverse switch; grounds via common Black Negative wire

  4. Throttle Harness: 3-Wire Signal (0.8V–4.2V Speed Control)

  5. Electric Door Lock: Power Ignition Switch Input

  6. Intelligent Recognition: 2-Pin Self-Learning Loop (White Wires)
