DC12V/40A, DC24V/20A |
Product Description
Features descriptions:
1. Three stages variable charging voltage algorithm by timing for maximizing the battery lifetime
2. Large charging capacity design (40A for 12Vdc mode, 20A for 24Vdc mode) for reduce the charge time
3. Selectable charging currents based on connected battery capacity for extending battery lifetime with optimized charging current
4. Multiple voltage charging design for protecting diverse types of batteries of Flooded Lead-Acid, Gel, AGM chemistries batteries
5. Wider input voltage range from 90Vac to 280Vac for universal input
6. High AC to DC converting efficiency design (higher than 80%)
7. Smart fan control -Build-in fan control firmware for controlling fan on/off status bases on charger operating mode. When the battery is charged, the fan will stop to reduce the noise and also extend the fan lifetime.

Protection
|
Input O ver V oltage
|
Unit must be safe for input voltage up to 300VacRMS (and up to 430Vpeak), need not be operating. Above this level the unit may be damaged.
|
Reverse B attery P olarity P rotection
|
Non-destructive reverse battery polarity protection with fuses. Unit shall not sustain damage and shall meet all specifications after fuse replacement.
|
Input Under-voltage
|
Unit must not be damaged for all input voltages from 0-300Vac. Shutdown or input current limit or other means may be applied when input voltage is out of normal operating range.
|
Output over voltage
12/24V mode
|
Unit will shut down if Vcharging > Vcharging (target) + 1.0Vdc for more than 2 seconds; unit will restart when voltage <= Vcharging (target) for more than 2 seconds.
For battery OVP the unit will restart in the same stage.
|
Unit will shut down if Vcharging > Vcharging (target) + 1.5Vdc for more than 2 seconds; unit will restart when voltage <= Vcharging (target) for more than 2 seconds.
For battery OVP the unit will restart in the same stage.
|
Charger over temperature protection
|
The internal temperatures of the charger will be measured by NTC. Based on these measurements, unit will shut down if the temperature exceeds 60°C. Unit will restart when environment temperature cools to 55 'C
