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 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.
