The PFC-824 15V 2A AC to DC Charger Fan Power Supply Board is a universal switching mode power supply (SMPS) module designed as a replacement part for 12V rechargeable emergency fans and air coolers [Image 1, Image 6]. It converts domestic mains AC power into a stable 15V DC, 2A (30W) output to concurrently run the DC fan motor and recharge internal batteries safely [Image 1, Image 4].
⚡ Key Features
- Dual Functionality: Powers the fan directly from the mains while delivering a float charge to internal 12V lead-acid or lithium batteries [Image 1, Image 6].
- Universal Compatibility: Dropped-in replacement module for popular rechargeable fan brands including Walton, Sunca, Defender, and Click [Image 6].
- Built-in Circuit Protection: Features an onboard glass tube safety fuse to guard against utility power surges and short circuits [Image 1].
- Efficient Heat Management: Equipped with a dedicated aluminum vertical heatsink to prevent thermal overheating during long-duration charging cycles [Image 1].
- Clean Power Delivery: Utilizes high-capacity electrolytic filter capacitors to ensure smooth, ripple-free, hum-less fan motor operation [Image 1, Image 27].

💡 Core Operational Mechanics
This internal PCB (Printed Circuit Board) acts as the bridge between your high-voltage mains AC supply and the low-voltage DC electronics of the appliance [Image 12]:
- AC Input Conversion: It steps down domestic 110V–240V AC power through an onboard standard 2-pin figure-8 power terminal socket [Image 1, Image 10].
- Voltage Regulation & Isolation: Utilizing a central high-frequency switching isolation transformer (yellow-wrapped ferrite core core), it safely drops and stabilizes the energy into a fixed, ripple-free 15V DC output capable of delivering up to 2A (30W continuous load) [Image 1, Image 4].
- Dual-Channel System Supply:
- Battery Charging Channel: It provides the calibrated float charge voltage required to fully recharge integrated 12V Sealed Lead-Acid (SLA) or Lithium-ion battery packs safely [Image 1, Image 6].
- Fan Operation Channel: It concurrently provides enough current to run the multi-speed internal DC fan motor and auxiliary LED emergency light clusters directly from the mains without stressing the battery [Image 9].

⚙️ Premium Hardware Architecture
Built with reliability in mind for long-duration operation, the layout contains dedicated safety and regulation stages:
- Overcurrent Overload Safeguards: Features a front-facing glass tube safety fuse near the AC terminal block that instantly snaps to break the circuit in the event of an unexpected utility spike or short circuit, saving your fan’s main logic control board [Image 1].
- Advanced Ripple Filtering: Outfitted with heavy-duty, high-temperature electrolytic capacitors (including dual low-ESR capacitors on the secondary stage) to clean up noise and ensure smooth, hum-free DC fan performance [Image 1, Image 27].
- Robust Thermal Dissipation: The main high-power switching transistor is mounted flush against a vertical, corrugated solid aluminum heatsink, allowing prolonged operation without thermal throttling or heat failure [Image 1].
- Clear Pin Tracking: Clean white silkscreen printing provides explicit labels (PFC-824, 15V2A) for painless wire tracing and orientation during repair swaps [Image 1].
