Short-circuit protection Constant-current limiting; recovers automatically after the fault is removed. Overvoltage protection 61–78 V; shuts down output voltage, with re-powering required for recovery. Overtemperature protection When Tcase exceeds the 85°C ±5°C threshold, output power derates automatically by up to 6% per °C. This is a case-temperature protection condition, not permission to exceed the rated +85°C case limit. Control and dimming 3-in-1 dimming Apply one method between DIM+ and DIM−: 0–10 VDC; an external 10 V PWM signal at 100 Hz–3 kHz; or resistance. Dimming-source current from the driver is 100 μA typical. Dimming range and OFF Minimum dimming level is about 8%; output current is undefined for 0% < Iout < 8%. Output can fall to 0% at approximately 0 VDC, 0 Ω, or 0% duty of a 10 V PWM signal. This is not a continuously defined 0–8% operating region. Control characteristic The plotted range uses 1–10 VDC or 10–100% PWM duty for approximately 10–100% output current. Resistance uses 10 kΩ/N to 100 kΩ/N for 10–100%, where N is the number of drivers in synchronized operation. Dimming wiring boundary Do not connect DIM− to Vo−. Direct LED connection is suggested; this dimming arrangement is not suitable for use with additional drivers. Temperature and reliability Case temperature Tcase −40 to +85°C; maximum case temperature +85°C. This is a case limit, not an ambient-temperature rating. Use the marked tc measuring point and the applicable load curve. Cooling and load curves Fanless free-air convection in the recommended horizontal mounting direction. The ambient curve is 100% through +40°C and ends there; the Tcase curve is 100% through +85°C. The −40 to −30°C cold region is marked 230 VAC input only. Respect both ambient and case limits; do not infer a higher-temperature operating region from the protection response. Input/load derating At 60 Hz: 85% load from 100 to 180 VAC, increasing to 100% at 200 VAC, then 100% through 305 VAC. Apply the exact 256/301 W limits and corresponding I–V envelopes. Performance-plot conditions PF is plotted in constant-current operation at Tcase 75°C. THD and efficiency plots use ELGC-300-L at Tcase 75°C; the model-specific efficiency table remains applicable.

Output constant power adjustable via the built-in Io potentiometer plus 3-in-1 dimming (0–10 VDC, 10 V PWM or resistance). Select the load within the model’s I–V envelope, not by combining independent voltage and current maxima. Download MEAN WELL ELGC-300 Datasheet (PDF)Download MEAN WELL LED Installation ManualCatalog pages 120–130; specification revision 2026-02-04. Use the exact model and suffix when selecting wiring and operating conditions. Output and constant-power envelope Default output current 2800 mA. This is the factory default, not a statement that the entire current range is available at every output voltage. Rated output power 301 W at 200–305 VAC; 256 W at 100–180 VAC. The family is marketed as 300 W; use the detailed 301/256 W table and operating envelope for selection. Constant-current region 58–116 V. The usable voltage/current combination must remain inside the applicable I–V plot. Full-power current range 2600–4000 mA at the high-input full-power envelope. The series describes full power over the 65–100% operating region. Current adjustment envelope 1300–4000 mA at 200–305 VAC; 1300–3400 mA at 100–180 VAC. Adjustment access and control method depend on this exact suffix. Maximum open-circuit voltage 120 V. Current ripple and tolerance Ripple: 5.0% maximum at rated current. Current tolerance: ±5%. Exact function Output constant power adjustable via the built-in Io potentiometer plus 3-in-1 dimming (0–10 VDC, 10 V PWM or resistance). IP rating IP67. Installation, sealing and any adjustment-access weather restrictions remain applicable; do not immerse the unit. 230 VAC I–V boundary The illustrated operating polygon is bounded by (1300 mA, 116 V), (2600 mA, 116 V), (4000 mA, 75.4 V), (4000 mA, 58 V), (2600 mA, 58 V). Remain within the shaded region and the rated-power limit. 115 VAC I–V boundary The low-line red boundary uses (1300 mA, 116 V), (2210 mA, 116 V), (3400 mA, 75.4 V), (3400 mA, 58 V), (2600 mA, 58 V). Remain within the reduced envelope; the plotted corner coordinates are catalog values. Built-in adjustment The underside Io potentiometer selects the operating current within the applicable envelope. Do not exceed the LED module current rating or the driver’s total-power limit. Catalog option status Listed as a standard/in-stock option in the catalog; this is not a live inventory statement. Input and performance Input supply 100–305 VAC or 142–431 VDC; AC frequency 47–63 Hz. Low-input output derating applies. Setup time 500 ms at 115 VAC and 230 VAC. Efficiency 93.5% typical for the M current range. Power factor Built-in active PFC; PF ≥0.97 at 115 VAC, ≥0.95 at 230 VAC and ≥0.92 at 277 VAC, at full load. Total harmonic distortion THD <10% at load ≥50% on 115/230 VAC and ≥75% on 277 VAC. AC input current 3 A at 115 VAC; 1.6 A at 230 VAC; 1.3 A at 277 VAC; typical. Inrush current Cold start: 45 A typical at 230 VAC; 1200 μs pulse width measured at 50% of peak, per NEMA 410. Circuit-breaker loading Catalog maximum on a 16 A breaker at 230 VAC: 2 units on type B; 4 units on type C. Check the actual breaker and installation conditions. Leakage current <0.75 mA at 277 VAC. Internal switching frequencies PFC oscillator: 45 kHz; PWM oscillator: 100 kHz. These are internal converter frequencies. Standby consumption <0.5 W when dimming is OFF, as specified for AB/ADA. Protection Protection functions The cover lists OCP, SCP, OVP and OTP. Apply the detailed recovery conditions below. Short-circuit protection Constant-current limiting; recovers automatically after the fault is removed. Overvoltage protection 121–145 V; shuts down output voltage, with re-powering required for recovery. Overtemperature protection When Tcase exceeds the 85°C ±5°C threshold, output power derates automatically by up to 6% per °C. This is a case-temperature protection condition, not permission to exceed the rated +85°C case limit. Control and dimming 3-in-1 dimming Apply one method between DIM+ and DIM−: 0–10 VDC; an external 10 V PWM signal at 100 Hz–3 kHz; or resistance. Dimming-source current from the driver is 100 μA typical. Dimming range and OFF Minimum dimming level is about 8%; output current is undefined for 0% < Iout < 8%. Output can fall to 0% at approximately 0 VDC, 0 Ω, or 0% duty of a 10 V PWM signal. This is not a continuously defined 0–8% operating region. Control characteristic The plotted range uses 1–10 VDC or 10–100% PWM duty for approximately 10–100% output current. Resistance uses 10 kΩ/N to 100 kΩ/N for 10–100%, where N is the number of drivers in synchronized operation. Dimming wiring boundary Do not connect DIM− to Vo−. Direct LED connection is suggested; this dimming arrangement is not suitable for use with additional drivers. Temperature and reliability Case temperature Tcase −40 to +85°C; maximum case temperature +85°C. This is a case limit, not an ambient-temperature rating. Use the marked tc measuring point and the applicable load curve. Cooling and load curves Fanless free-air convection in the recommended horizontal mounting direction. The ambient curve is 100% through +40°C and ends there; the Tcase curve is 100% through +85°C. The −40 to −30°C cold region is marked 230 VAC input only. Respect both ambient and case limits; do not infer a higher-temperature operating region from the protection response. Input/load derating At 60 Hz: 85% load from 100 to 180 VAC, increasing to 100% at 200 VAC, then 100% through 305 VAC. Apply the exact 256/301 W limits and corresponding I–V envelopes. Performance-plot conditions PF is plotted in constant-current operation at Tcase 75°C. THD and efficiency plots use ELGC-300-L at Tcase 75°C; the model-specific efficiency table remains applicable. Humidity and storage Operating: 20–95% RH, non-condensing. Storage: −40 to +80°C, 10–95% RH, non-condensing. Temperature coefficient ±0.03%/°C over 0–60°C.

ErP installation Use behind a switch; do not permanently connect this driver to the mains, as stated by the catalog’s ErP note. Specification conditions Unless separately stated: 230 VAC input, rated current and 25°C ambient temperature. Verify the finished installation’s EMC performance again. 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 This 3Y version has a three-wire input with a green/yellow PE/FG conductor.
