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 Mean Well GC120A12-R7B designed for?
The GC120A12-R7B is an AC-DC battery charger rated at 102W. It provides a 13.6V DC output at 7.5A, making it suitable for 12V-class battery charging applications, with a recommended battery capacity of 40 to 100Ah. Its compact adaptor-style design is intended for professional and commercial use.
What are the key electrical specifications of the GC120A12-R7B?
This model is rated for 102W output with a nominal output of 13.6V DC and 7.5A. It accepts a universal input range of 85 to 264VAC or 120 to 370VDC. The unit also includes PFC (power factor above 0.97 at 230VAC) and has a typical efficiency of 86.5%.
What type of output connector does the GC120A12-R7B use?
The standard DC plug on this model is a 4-pin Power DIN (KYCON KPP-4S or equivalent), identified as R7B. That connector style is a defining feature of this specific variant. Buyers should confirm that their equipment matches the R7B 4-pin Power DIN plug before ordering.
Can the GC120A12-R7B be used in demanding temperature conditions?
This charger is specified for operation from -30°C to +70°C, subject to the manufacturer's derating guidance. That makes it suitable for a wide range of industrial environments. It also has over temperature protection, which shuts down the output and recovers when re-powered.
What protection features are included in the GC120A12-R7B?
The GC120A12-R7B includes protection against short circuit, overload, over voltage, and over temperature. Overload protection operates at 90 to 110% of rated output power with constant current limiting and auto-recovery. Over-voltage protection shuts down the output and requires re-powering to recover.
How does this model compare with a standard fixed-output power adaptor?
Compared with a basic adaptor, the GC120A12-R7B adds features that are useful in professional charging applications, including PFC, a 2-stage charging characteristic, and status indication through a 2-color LED. It also offers a 4-pin Power DIN output plug rather than a generic DC barrel style. These differences make it better suited to applications that need a purpose-built battery charger.
