Defender KN-2926 Charger Fan Circuit regulates power flow for 16-inch rechargeable cooling units. It manages the transition between AC mains and 12V DC battery power. This module controls motor speed while charging internal lead-acid cells.
Key Features
- Dual Power Input: 12V DC and AC operation modes integrated. Fan stays operational during frequent load shedding.
- Battery Management: Automatic overcharge and discharge protection thresholds. Circuitry blocks voltage spikes from damaging the battery.
- Lighting Interface: Direct connection pins for 8-LED emergency light boards. Lights activate when the primary power cuts.
- 16-Inch Compatibility: Current output calibrated for 16-inch desktop fan motors. PCB sustains high RPM without overheating components.
Frequently Asked Questions
How to repair KN-2926 fan circuit?
Swap the full PCB if the charging module stops responding. Vibration or road dust often cracks terminal solder points over time.
Is KN-2926 circuit compatible with 6V fans?
This board operates strictly on a 12V DC system. Connecting 6V components causes immediate hardware failure due to overvoltage.
