Product Description
The JS-2936S-2-SMT is a 12V replacement motherboard circuit board designed for AC/DC rechargeable emergency table fans [Image 1, Image 2]. It serves as a universal repair module compatible with major brands like Kennedy, Defender, and Sunca [Image 1].
Core Features
- Smart Charge Controller: Automatically regulates power input to prevent battery overcharging and deep discharging [Image 1].
- Visual Interface: Integrated single-digit 7-segment display shows current fan speed level alongside LED status indicators [Image 1].
- Power Management: Designed to interface directly with a 12V lead-acid battery and 15V step-down transformer input [Image 1, Image 2].
- Multi-Speed Controls: Built-in tactile micro-switches manage multi-stage airflow speed adjustments and power modes.
If you are replacing an old board, let me know:
- What fan brand or model are you installing this into?
- Do you need help identifying the wiring connection points (Battery, Transformer, or Motor terminals)?

Key Technical Features
-
- Advanced Battery Protection Modules: Equipped with intelligent overcharge and over-discharge protection parameters. It monitors voltage thresholds to stop charging when full and disconnects the load before the battery drops below unsafe voltages, dramatically extending the lifespan of your 12V lead-acid or lithium-ion battery.
- Integrated 7-Segment LED Display: Features an onboard single-digit digital display panel that gives real-time visual feedback on fan speed steps, operation modes, and error status tracking.
- Multi-Speed Dynamic Control: Supports seamless multi-stage or step-less wind speed regulations, managing power distribution to the fan motor efficiently to conserve energy during power outages.
- Peripherals Control UI: Onboard push buttons coordinate primary functions such as power switching, speed increments, and light toggle controls. Five built-in green LEDs provide immediate diagnostic visual references for speed and mode indicators.
- Auxiliary Power Connectivity: Includes dedicated output terminals designed to supply steady low-voltage power for auxiliary LED nightlights or USB mobile charging interfaces.
