Model and charging selection
| Complete order code |
GC220A24-R7B |
| Series and voltage code |
GC220: single-output battery charger. A24 identifies the 24 V battery-voltage code; the typical charger output is 27.2 V. |
| Selected connector code |
R7B; standard configuration with four-pin power DIN (R7B). |
The series is intended for lead-acid batteries (flooded, gel and AGM) and Li-ion battery applications described as lithium iron and lithium manganese in the catalogue. Charger specifications may require modification for the particular battery. Confirm compatibility with the battery manufacturer and MEAN WELL; nominal battery voltage alone is insufficient.
Charging output
| Typical charging voltage |
27.2 V DC. |
| Continuous output current (typical) |
8 A. |
| Rated output power |
217.6 W. |
| Recommended battery capacity |
40–125 Ah; manufacturer-suggested range. Observe the battery manufacturer's maximum charging-current limit. |
| Charging stages and indication |
Stage 1: constant current (CC), red LED. Stage 2: constant voltage (CV) / floating charge, green LED. |
| Constant-current operating region |
50–100% of rated output voltage. The charging curve shows current tapering during CV operation toward its 10% reference line. |
The charging curve is a stage illustration, not a fixed charging-time guarantee. Respect the specified current and power limits as well as the battery's permitted charging profile.
AC and DC input
| Input voltage and frequency |
90–264 VAC or 127–370 VDC; 47–63 Hz AC. |
| Input class and inlet |
Class I with protective earth; three-pole IEC320-C14 AC inlet. Use a suitable grounded mains connection. |
| Active PFC / power factor (typical) |
Built-in active PFC; PF >0.90 at 230 VAC and >0.98 at 115 VAC, full load. |
| Efficiency (typical) |
92.5%, under the default 230 VAC / rated-load / 25°C test conditions. |
| AC current |
4 A at 115 VAC; 2 A at 230 VAC. |
| Inrush / leakage / no-load power |
Inrush maximum 120 A at 230 VAC; leakage maximum 1.5 mA at 240 VAC; no-load consumption <1 W. |
Protection
| Overload |
90–110% of rated output power; constant-current limiting, with automatic recovery after the fault is removed. |
| Short circuit |
Hiccup mode, with automatic recovery after the fault is removed. |
| Overvoltage |
105–135% of rated output voltage; output shutdown, re-power to recover. |
| Overtemperature |
95±10°C, sensed by TSW1; power-transistor heatsink. Output shuts down; it recovers automatically after the temperature falls. This is a protection-sensor threshold, not the permitted external ambient temperature. |
Cooling and derating
| Working temperature and cooling |
-30 to 60°C, subject to the derating curves; free-air convection, horizontal orientation. |
| Temperature curve at 230 VAC |
-30°C: 100%; 50°C: 100%; 60°C: 80%. Reduce load along the sloped section. |
| Temperature curve at 100 VAC |
-30°C: 100%; 40°C: 100%; 60°C: 50%. Reduce load along the sloped section. |
| Input-voltage curve |
90 VAC: 90%; 100 VAC: 100%; 264 VAC: 100%; AC test frequency 60 Hz. |
Apply input-voltage and temperature derating together; the maximum ambient rating does not imply full-load operation.
Above 2000 m, reduce allowable ambient temperature by 3.5°C per additional 1000 m for these fanless units. This temperature correction is not a separately specified maximum operating-altitude approval.
Environment and reliability
| Humidity |
Working: 20–90% RH, non-condensing. Storage: 10–95% RH. |
| Storage temperature |

The specified connector is fitted to this model's output lead. Confirm the mating connector against the complete drawing; a separate mating part or adapter kit is not listed as included.
Other output plugs and cable types are available by customer request. Confirm the complete approved configuration with the supplier; the R7B and AD1 versions are distinct order codes.
The AC inlet is specified, but an included AC mains cord is not identified in these pages. Confirm regional cord supply with the seller.
