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 GC120A48-AD1 designed for?

The GC120A48-AD1 is an AC/DC battery charger rated at 120.2W. It provides a 54.4V output at 2.21A and is suited to applications that require a compact external charger with an Anderson connector output. Its 167 x 67 x 35 mm size and 0.62 kg weight make it suitable for portable and bench-side commercial use.

What are the key electrical ratings of the GC120A48-AD1?

This model is rated for 120.2W output power, with a nominal output of 54.4V DC and 2.21A. It accepts a universal 85 to 264VAC input range, and also supports 120 to 370VDC input. Typical efficiency is 91%, with a power factor above 0.97 at 230VAC.

Does the GC120A48-AD1 include charger protections?

Yes, this model includes protection for 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 at 59 to 69V and requires re-powering to recover.

Can this charger be used in demanding temperature conditions?

The GC120A48-AD1 has a specified operating temperature range of -30°C to +70°C, subject to the derating curve. That makes it appropriate for a wide range of industrial and commercial environments where ambient temperature can vary significantly. Buyers should still confirm the full operating conditions of their enclosure or end equipment.

What charging features does this model offer?

This charger uses a 2-stage charging characteristic and includes a 2-color LED indicator for charging status. It also includes PFC (power factor above 0.97 at 230VAC) and over temperature protection. These features support efficient operation in a compact charger format.

What output interface and cable details come with the GC120A48-AD1?

The standard DC output connector is an Anderson connector (AD1; housing Anderson 1327FP red / 1327G6FP black). The output cable length is specified as 1200mm ±50mm using SJTW, 18AWG x 2C cable. This is useful for buyers who need to confirm fitment with existing equipment specifications.

What compliance and warranty information is available for this charger?

The GC120A48-AD1 is listed with UL1012 (for GC120Axx-AD1 models), TUV BS EN/EN62368-1, PSE J62368-1 and EAC TP TC 004 approvals. EMC standards listed include EN55032 Class B, FCC Part 15 Class B, and multiple EN61000 immunity and harmonic standards. The datasheet does not state a warranty period, so confirm warranty terms before ordering.
