Key Technical Features & Functionalities
- Intelligent Dual-Source Smart Switching: Integrated with an onboard automated solid-state relay circuit that continuously monitors incoming grid power. When AC grid power is present, the board seamlessly routes currents to power the fan and charge the storage cells; upon power blackout, it instantly flags a zero-latency switchover to internal DC battery reserves.
- 7-Segment Digital Speed Display: Features a bright, centered 1-digit 7-segment LED panel module that provides real-time visual tracking of active fan speed thresholds, numerical settings, or system operation diagnostic codes.
- Integrated Multi-Stage Advanced Protection Systems: Engineered with proprietary overcharge protection voltage limits and over-discharge current drain inhibitors. This design aggressively prevents chemical degradation, internal short-circuit threats, and thermal bloating in connected lead-acid or lithium-ion backup cells.
- Multi-Step Fan Speed & Light Interfacing: Outfitted with physical micro-tactile push buttons and integrated transistor arrays capable of handling multi-tier variable speed modulation (Low/Medium/High) alongside discrete LED array emergency illumination driver arrays.
- USB Device Charging Base: Hosts a surface-mounted USB Type-A port configured to output a stable 5V DC pipeline, transforming your emergency fan unit into a structural power bank station for charging smartphones and external micro-gadgets during prolonged utility outages.
- LED Status Cluster: Accompanied by standalone peripheral red, green, and amber LED indicator lamps to give instant visual updates on current AC grid connection, battery charging progression, and low power warnings.
