Notes ?
- All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25°C of ambient temperature.
- Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
- Tolerance: includes set up tolerance, line regulation and load regulation.
- Please refer to "DRIVING METHODS OF LED MODULE".
- De-rating may be needed under low input voltages. Please refer to "STATIC CHARACTERISTIC" sections for details.
- Length of set up time is measured at first cold start. Turning ON/OFF the driver may lead to increase of the set up time.
- The driver is considered as a component that will be operated in combination with final equipment. Since EMC performance will be affected by the complete installation, the final equipment manufacturers must re-qualify EMC Directive on the complete installation again. (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)
- To fulfill requirements of the latest ErP regulation for lighting fixtures, this LED driver can only be used behind a switch without permanently connected to the mains.
- This series meets the typical life expectancy of >62,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 75°C or less.
- Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com
- The ambient temperature derating of 3.5°C/1000m with fanless models and of 5°C/1000m with fan models for operating altitude higher than 2000m(6500ft).

Block Diagram ?️
The block diagram illustrates the internal components and signal flow of the HLG-120H LED driver. The input (I/P) passes through an EMI FILTER & RECTIFIERS, followed by a PFC CIRCUIT and POWER SWITCHING stage. Control signals are managed by PFC CONTROL, PWM CONTROL, O.L.P. (Over Load Protection), O.T.P. (Over Temperature Protection), and O.V.P. (Over Voltage Protection). The output stage includes RECTIFIERS & FILTER, and a DETECTION CIRCUIT, providing the final output voltages (+V, -V) and dimming signals (DIM+, DIM- for B-Type models).
Driving Methods of LED Module ?
This series is designed to operate in either Constant Current mode (direct drive) or Constant Voltage mode (typically with an additional DC/DC driver) to power LEDs.
The graph "Vo(%) vs Io (%)" illustrates the operational regions. Region (A) represents the Constant Voltage area, where the output voltage is regulated. Region (B) represents the Constant Current region, where the output current is regulated. In the constant current region, the maximum output voltage depends on the configuration of the end systems. Contact MEAN WELL for compatibility issues.
Dimming Operation ?️
The HLG-120H series offers a 3-in-1 dimming function for B/AB-Type models. The output constant current level can be adjusted using one of three methodologies applied between the DIM+ and DIM- terminals: 1~10VDC, 10V PWM signal, or resistance. Direct connection to LEDs is suggested, and it is not suitable for use with additional drivers. The dimming source current from the power supply is approximately 100μA (typ.).
Applying additive 1 ~ 10VDC
A diagram shows the connection for additive voltage dimming, with DIM+ and DIM- terminals connected to an external voltage source. A warning states "DO NOT connect 'DIM- to -V'".
The accompanying graph shows "Output current (%)" versus "Dimming input: Additive voltage" (1V to 10V), demonstrating a linear relationship where 1V corresponds to approximately 10% output current and 10V corresponds to 100% output current.
Applying additive 10V PWM signal (frequency range 100Hz ~ 3KHz)
A diagram illustrates the connection for additive PWM signal dimming. A warning states "DO NOT connect 'DIM- to -V'".
The accompanying graph shows "Output current (%)" versus "Duty cycle of additive 10V PWM signal dimming input" (10% to 100%), showing a linear relationship.
Applying additive resistance
A diagram shows the connection for additive resistance dimming. A warning states "DO NOT connect 'DIM- to -V'".
The accompanying graph shows "Output current (%)" versus "Dimming input: Additive resistance" (ranging from 10K/N to 100K/N Ohms, where N is the driver quantity for synchronized dimming operation), demonstrating a linear relationship.
Dimming Control Example ?️
This section provides a wiring diagram for controlling the lighting fixture's ON/OFF and dimming. It shows connections for AC source (N, FG, L) to a Relay, Switch, and Adjuster. The HLG-120H (B-Type) is connected via its DIM+ and DIM- terminals to the adjuster, which can be set up using 10K/N~100K/N Ohms resistance, 1~10V DC Voltage, or 10V PWM Signal. The output (+V, -V) connects to the LED Lighting Fixture. A switch and relay can be used to turn the lighting fixture ON/OFF.
Performance Characteristics ?
Output Load vs Temperature (Note.10)
Two graphs illustrate derating based on temperature. The first graph plots LOAD (%) against AMBIENT TEMPERATURE, Ta (°C), showing 100% load capacity up to 50°C, followed by a linear derating to 0% at 70°C. The second graph plots LOAD (%) against Tcase (°C), indicating 100% load capacity up to 75°C, with linear derating to 0% at 80°C.
Static Characteristics ?
This graph plots LOAD (%) against INPUT VOLTAGE (V) at 60Hz. It shows that the driver maintains 100% load capacity across a wide input voltage range, from approximately 90V up to 305V. A note indicates that de-rating is needed under low input voltages.
Power Factor (PF) Characteristic ?
The graph shows the Power Factor (PF) versus LOAD (%) at Tcase = 70°C for the Constant Current Mode. For all input voltages (115Vac, 230Vac, 277Vac), the PF remains high, generally above 0.90, and approaches 1.00 at higher load percentages.
Total Harmonic Distortion (THD) ?
This graph displays THD (%) versus LOAD (%) for the 48V Model at Tcase = 70°C. It shows that THD is relatively low, especially at higher load percentages, with values generally below 20% for 115Vac and 230Vac inputs, and slightly higher for 277Vac input.
Efficiency vs Load ?
The graph illustrates EFFICIENCY (%) versus LOAD (%) for the HLG-120H series (48V Model, Tcase at 70°C). The efficiency is high across the load range, reaching up to 93.5% at full load for 230Vac and 277Vac inputs, and around 92% for 115Vac input.
Life Time ⏳
The graph shows LIFETIME (Kh) versus Tcase (°C). It indicates a typical lifetime of over 100,000 hours (100 Kh) when the case temperature (Tcase) is below approximately 60°C. The lifetime decreases as the case temperature increases, reaching about 50,000 hours at 80°C.
