Test conditions and notes7
- 1. Modification for charger specification may be required for different battery specification. Please contact battery vendor and MEAN WELL for details.
- 2. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
- 3. This is MeanWell's suggested range, please consult your battery manufacturer for their suggestions about maximum charging current limitation.
- 4. Derating may be needed under low input voltage. Please check the derating curve for more details.
- 5. Constant current operation region is within 50~100% rated output voltage.
- 6. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives.(as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )
- 7. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).

FAQ
What is the output rating of the Mean Well GC120A24-AD1?
The GC120A24-AD1 is rated for 120.2W with a 27.2V DC output and 4.42A continuous output current. That makes it a battery charger for 24V-class charging applications that need a 27.2V output.
What input power range does the GC120A24-AD1 support?
This model accepts a universal 85 to 264VAC input range and also supports 120 to 370VDC input. Its power factor is above 0.97 at 230VAC and above 0.99 at 115VAC at full load, for broad mains compatibility.
What kinds of applications is the GC120A24-AD1 best suited for?
The GC120A24-AD1 is intended for 24V battery charging duties where a 27.2V, 4.42A output is appropriate, with a recommended battery capacity of 20 to 65Ah. Buyers typically look at this type of unit for service or bench charging needs where a compact 167 x 67 x 35 mm charger is preferred.
What protection features are built into the GC120A24-AD1?
This charger includes short circuit, overload, over voltage, and over temperature protection. Overload protection operates at 90 to 110% of rated output power with constant current limiting and auto-recovery, while over voltage protection (29 to 33V) shuts down the output and requires re-powering to recover.
Can the GC120A24-AD1 be used in demanding temperature conditions?
The specified working temperature range is -30 to +70 degrees C, subject to the derating curve. Over temperature protection shuts down the output if the internal temperature gets too high, and re-powering is needed to recover.
What connector and cable does the GC120A24-AD1 use on the DC output side?
The AD1 version uses an Anderson connector (housing Anderson 1327FP red / 1327G6FP black, 261G2 contacts or equivalent). The output cable length is 1200mm ±50mm and uses SJTW 18AWG 2-conductor cable.
How does the GC120A24-AD1 compare with lower-power 24V chargers?
The main difference is output capacity: the GC120A24-AD1 delivers up to 120.2W and 4.42A at 27.2V. For buyers comparing 24V chargers, this model is positioned for applications that need more charging current than smaller wattage units can provide.
What status and efficiency features does the GC120A24-AD1 offer?
This model provides a 2-color LED indicator (red while charging, green in float charging) and uses a 2-stage charging characteristic. Its typical efficiency is 90%.
