Input/load derating
At 60 Hz: 80% load at 90 VAC, rising to 100% at 110 VAC; 100% is shown from 110 to 305 VAC. Observe the simultaneous thermal and output limits.
Adjustment and control
3-in-1 control
Apply 1–10 VDC, a 10 V PWM signal at 100 Hz–3 kHz, or resistance between DIM+ and DIM−. Dimming-source current: 100 µA typical.
Control leads
DIM+ is purple; DIM− is pink. SJOW 17 AWG × 2C / H05RN-F 2 × 1.0 mm², 300 ±20 mm.
Resistance and shared controllers
10 kΩ/N to 100 kΩ/N corresponds to 10–100% current. N is the number of drivers controlled by the same dimming circuit. Verify controller capacity and interface compatibility.
Low-end dimming and switch-off
The analog dimming curves cover approximately 10–100% output current. Use an external AC switch or relay as shown in the catalog for 0% output; do not assume the 1–10 V control alone provides dim-to-off.
Dimming connection restrictions
Do not connect DIM− to Vo−. Connect the driver directly to the LEDs; an additional driver in the LED path is not suitable for the illustrated dimming application.
Protection and insulation
Short-circuit protection
Constant-current limiting; automatically recovers after the fault is removed.
Overvoltage protection
250–275 V. Shuts down the output; re-power on to recover.
Overtemperature protection
Shuts down the output and recovers automatically after temperature falls.
Dielectric withstand
Input–output: 3.75 kVAC; input–FG: 2 kVAC; output–FG: 1.5 kVAC
Insulation resistance
100 MΩ at 500 VDC / 25°C / 70% RH, input–output, input–FG and output–FG
Temperature and operating conditions
Working case temperature
Tcase −40 to +90°C; maximum case temperature +90°C. Case temperature is not ambient temperature.
Ambient-temperature/load curve
Horizontal mounting: 100% load through +50°C at 110 VAC, or +60°C at 230 VAC; derate along the applicable curve to 60% load at +70°C. The ambient curve ends there. Maintain the case-temperature limit simultaneously.
Case-temperature/load curve
The horizontal-mounting Tcase curve shows 100% load from −40°C through +90°C, then ends. This does not override ambient or low-input derating.
Working humidity
20–95% RH, non-condensing
Storage conditions
−40 to +80°C; 10–95% RH
Altitude derating
Above 2000 m (6500 ft), reduce ambient-temperature allowance by 3.5°C per additional 1000 m for this fanless driver.
Vibration
10–500 Hz; 5 G; 12 minutes per cycle; 72 minutes along each X, Y and Z axis.
Specification and performance-plot conditions
Unless otherwise stated, specifications are measured at 230 VAC input, rated current and 25°C ambient. PF plots use Tcase 80°C; THD and efficiency plots illustrate the 1400 mA model at that case temperature and do not replace the specific model ratings.

Installation safety
Disconnect the mains supply and prevent accidental reconnection before installation or maintenance. Have faults examined by a qualified technician; do not open the power-supply case yourself.
Ventilation and mounting
Keep ventilation clear and do not stack objects on the unit. Keep 10–15 cm clearance when the adjacent device is a heat source. Follow this model’s mounting, ambient-temperature and output-derating requirements.
System wiring and protection
Use approved primary and secondary wiring rated for at least the applicable unit current. Provide suitable system-level insulation and an enclosure around single-insulated wiring; verify EMC again in the completed system.
Environmental and load limits
Do not immerse the unit or install it near fire or above its specified ambient limit. Keep output current and power within the model’s rated operating envelope. If a fitted external flexible cable is damaged, replacement is limited to the manufacturer, its service agent or a similarly qualified person.
Connection seals and support
If waterproof connectors are fitted, secure their connections to prevent water entry. Verify the mounting structure and luminaire strength; use safety cables for bay-light applications.
Protective-earth installation
Connect the fitted FG/PE conductor to PE according to this Class I model’s wiring diagram.
Weather protection
This IP65 model must be installed indoors or in a location sheltered from rain outdoors, as required by the installation manual. The IP rating does not permit immersion.
Controller installation
Verify the compatibility and capacity of the controller for this exact interface. For standalone use with dimming conductors smaller than 18 AWG (0.75 mm²), use SELV controllers/networks; contact MEAN WELL for guidance before using FELV control. Follow this model’s control wiring.
Dimming isolation
The installation manual lists this HLG-60H–320H-C family’s analog dimming circuit as not isolated from the secondary circuit. Follow the specified DIM wiring and controller requirements.
