Test conditions and notes7
  1. 1. Modification for charger specification may be required for different battery specification. Please contact battery vendor and MEAN WELL for details.
  2. 2. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
  3. 3. This is MeanWell's suggested range, please consult your battery manufacturer for their suggestions about maximum charging current limitation.
  4. 4. Derating may be needed under low input voltage. Please check the derating curve for more details.
  5. 5. Constant current operation region is within 50~100% rated output voltage.
  6. 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. 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 are the main output specifications of the Mean Well GC120A24-R7B?

The GC120A24-R7B is rated for 120.2W output with a 27.2V output voltage and 4.42A continuous output current. It is the 24V battery charger model in Mean Well's GC120 series.

What type of AC input does this charger support?

This model accepts a universal AC input range of 85 to 264VAC, and it also supports 120 to 370VDC input. That wide input range makes it suitable for use across many standard power environments without needing a region-specific version.

What output connector does the GC120A24-R7B use?

This version uses a 4-pin Power DIN DC plug (KYCON KPP-4S or equivalent), identified as the R7B type. Buyers should confirm their equipment is designed for the R7B 4-pin Power DIN plug before ordering.

Does this model include built-in protection features?

Yes. The GC120A24-R7B includes protection for short circuit, overload, over voltage, and over temperature. Its overload protection is specified at 90 to 110% of rated output power, using constant current limiting with auto-recovery.

Is the GC120A24-R7B suitable for demanding temperature environments?

This model is rated for operation from -30°C to +70°C, subject to the manufacturer's derating guidance. That gives it a broader operating range than many indoor-only commercial power adapters.

What makes this model a good fit for portable industrial or commercial use?

It combines a universal 85 to 264VAC input with PFC (power factor above 0.97 at 230VAC) and a -30°C to +70°C working range with derating. The compact 167 x 67 x 35 mm size and 0.62 kg weight also help when portability and space efficiency matter.

What compliance and approval information is listed for this charger?

The product is listed with TUV BS EN/EN62368-1, PSE J62368-1 and EAC TP TC 004 safety approvals, and the EMC specifications include EN55032 Class B, FCC Part 15 Class B, and multiple EN61000 immunity and harmonic standards. UL1012 is noted only for GC120Axx-AD1 variants, so buyers should not assume that approval applies to the R7B version.
