3、 Key functions
Automatic adaptation of charging mode
Float charging: The battery maintains 27.2VDC when fully charged, preventing overcharging and extending its lifespan
Boost: When the battery is depleted, it automatically boosts to 28.2VDC and quickly recharges
Automatic switching: intelligently switches based on battery voltage, without the need for manual intervention
Dual purpose design (charger+power supply)
Can charge the battery separately
Parallel connected batteries with load (seamless battery switching for power supply in case of power failure)
Can be used independently as a 24V regulated power supply (without battery)
LED status indication
Green: Power supply normal, output ready
Yellow: Charging in progress (evenly charged)
Red: Fault (overvoltage/overheating/short circuit)
Parallel redundancy (optional)
Multiple DCP2-2420 can operate in parallel, with equal current output, improving reliability and power
