Block Diagram
The block diagram illustrates the internal architecture of the XLG-50 series LED driver. The input power (I/P) first passes through an EMI Filter & Rectifiers stage, followed by a PFC Circuit. This is then processed by a Power Switching stage controlled by a PWM & PFC Control unit, which also monitors Over Temperature Protection (O.T.P.) and Over Load Protection (O.L.P.). The switched power is then rectified and filtered by Rectifiers & Filter, and further regulated by an O.L.P. and Detection Circuit to produce the output voltage (Vo+) and (Vo-). For the AB-Type models, there are additional DIM+ and DIM- terminals for dimming control. The metal casing is connected to Protective Earth.
Driving Methods of LED Module
This graph illustrates the relationship between output voltage and output current for the LED module, indicating the recommended performance region. The X-axis represents Output Current in milliamperes (mA) from 0mA to 2450mA, and the Y-axis represents Output Voltage in volts (V) from 0V to 54V. Key operating points shown include (530mA, 54V), (1000mA, 54V), (1050mA, 22V), (2100mA, 24V), and (2100mA, 22V). The shaded area denotes the recommended performance region for optimal operation.
Dimming Operation
Wiring: The input power is connected via AC/N (Blue), AC/L (Brown), and PE (Green/Yellow) wires. The DC output is provided through V- (Black) and V+ (Red) wires. For the AB-Type models, DIM+ (Purple) and DIM- (Pink) wires are available for dimming control.
3 in 1 Dimming Function (for AB-Type)
The output constant current level can be adjusted using one of three methodologies applied between the DIM+ and DIM- terminals: 0~10VDC, 10V PWM signal, or resistance. Direct connection to LEDs is suggested; using additional drivers is not recommended. The dimming source current from the power supply is approximately 100μA (typ.).
Additive 0 ~ 10VDC Dimming
This graph shows the relationship between the percentage of output current and the additive input voltage from 0V to 10V. As the voltage increases from 0V to 10V, the output current increases linearly from approximately 0% to 100%.
Additive 10V PWM Signal Dimming
This graph illustrates the output current percentage based on the duty cycle of a 10V PWM signal, ranging from 0% to 100%. The dimming frequency range is 100Hz to 3KHz. A higher duty cycle results in a higher output current.
Additive Resistance Dimming
This graph depicts the output current percentage as a function of additive resistance. The X-axis shows resistance values from 'Short' (effectively 0Ω) to 100KΩ/N, where N represents the quantity of drivers for synchronized dimming. As the resistance increases, the output current decreases.
Note: The minimum dimming level is approximately 8%. The output current is not defined for Iout below 8%. The output current can drop to 0% when the dimming input is approximately 0kΩ, 0Vdc, or a 10V PWM signal with 0% duty cycle.
Performance Characteristics
Output Load vs Temperature
These graphs illustrate how the load capacity of the XLG-50 series is affected by ambient and case temperatures. The first graph shows Load (%) versus Ambient Temperature (°C) for 100VAC and 230VAC input, indicating that derating is required at higher ambient temperatures. The second graph shows Load (%) versus Case Temperature (°C) for 230VAC input, also demonstrating derating at elevated case temperatures.
Static Characteristic
This graph displays the Load (%) versus Input Voltage (V) at 60Hz. It shows the operating range and highlights that de-rating is necessary under low input voltage conditions to maintain stable operation.
Power Factor (PF) Characteristic
The Power Factor (PF) is plotted against Load (%) at a case temperature (Tcase) of 75°C for different input voltages (115V, 230V, 277V). The PF remains high, generally above 0.9, across most of the load range, indicating efficient power utilization.
Total Harmonic Distortion (THD)
This graph shows the Total Harmonic Distortion (THD) in percentage (%) versus Load (%) at a case temperature (Tcase) of 75°C for 115VAC, 230VAC, and 277VAC input. The THD levels are kept below 10% for most operating conditions.
Efficiency vs Load
The Efficiency (%) is plotted against Load (%) at a case temperature (Tcase) of 75°C for 115V, 230V, and 277V input. The XLG-50 series achieves high efficiency, reaching up to 90% in field applications.
Life Time
This graph illustrates the expected Life Time in thousands of hours (Kh) as a function of Case Temperature (Tcase) in °C. It shows that the lifetime significantly decreases as the case temperature rises above approximately 65°C, emphasizing the importance of thermal management for longevity.

- Refer to the "DRIVING METHODS OF LED MODULE" section for details.
- Setup time is measured at the first cold start; repeated ON/OFF cycles may increase setup time.
- De-rating may be required under low input voltage conditions; consult the "STATIC CHARACTERISTIC" section.
- The driver is a component for final equipment. EMC performance is affected by the complete installation; final equipment manufacturers must re-qualify EMC Directive. (See EMI statement)
- Typical life expectancy of >50,000 hours is achieved when Tcase (or tc point) is approximately 75°C or less.
- Refer to the warranty statement on the MEAN WELL website (www.meanwell.com).
- Input over voltage protection is applicable only for XLG-50 I series and I series without UL/CSA certificate.
