Test conditions and notes8
- 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. Test condition is at 25℃ the charging current vary with the ambient and components temperature. The lower temperature, the higher charging current.
- 6. Maximum charging current will be in the range of 85~110% rated output current.
- 7. The power supply is considered as an independent unit, but the final equipment still need to re-confirm that whole system complies with the EMC directives.(as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )
- 8. 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 kind of product is the Mean Well GC330A48-C4P?
The GC330A48-C4P is a 330W single-output battery charger in Mean Well's GC330 series. It provides a 54.4V charging voltage with 4.8A continuous (6A peak) charging current, over an output power range of 261.1 to 326.4W. This model is designed for buyers who need an external charger with built-in protection features.
What output does the GC330A48-C4P provide?
This model is rated for 54.4V DC output with 4.8A continuous and 6A peak charging current (typical). Its output power range is 261.1 to 326.4W. Those published ratings make it suitable for battery-charging applications that require this voltage and current range, with a recommended battery capacity of 20 to 65Ah.
What input power range does the GC330A48-C4P support?
The GC330A48-C4P accepts a universal AC input range of 90 to 264VAC, and it also supports 127 to 370VDC input. That broad input range helps simplify sourcing for international or multi-region use. Its typical power factor is above 0.95 at 230VAC and above 0.98 at 115VAC at full load; derating may be needed at low input voltage.
Can the GC330A48-C4P be used in demanding industrial or commercial environments?
This model has a specified working temperature range of -30 to +60°C, subject to the derating curve. It also includes protection for short circuit (hiccup mode, auto-recovery), over voltage, and over temperature. Those characteristics make it a practical option for many commercial and industrial charging environments where reliability matters.
How does the GC330A48-C4P compare with a standard desktop power adapter?
Compared with a typical consumer adapter, the GC330A48-C4P is a higher-power 330W-class battery charger (261.1 to 326.4W) built for 54.4V output. It offers a high power factor (PF>0.95), multiple safety and EMC approvals, and a two-color LED charging status indicator. Its 93.5% typical efficiency and 4-pin output connector also reflect a more industrial-oriented specification.
What certifications and warranty come with the GC330A48-C4P?
The spec sheet lists safety approval to UL62368-1, TUV BS EN/EN62368-1 and EAC TP TC 004. EMC compliance includes BS EN/EN55032 Class B, FCC Part 15 / CISPR22 Class B and CAN ICES-3(B). The spec sheet does not state a warranty period, so please confirm warranty terms before purchase.
