5-in-1 Universal Dimming Compatibility: A single driver supports all five major dimming protocols — Triac/Phase-Cut, 0–10V, 1–10V, 10V PWM, and Potentiometer — covering the full spectrum of commercial and residential dimming systems without requiring a protocol-specific SKU at the time of purchase.
-
Full Dimming Range — 0.1% to 100%: Achieves smooth, flicker-free dimming from 0.1% to 100% for precise scene control, energy management, and deep-dim applications across hospitality, retail, office, and residential LED lighting systems.
-
300W Constant Voltage Output — Two Voltage Models: Available in 12V DC at 25A (LMFV-300-12J005) or 24V DC at 12.5A (LMFV-300-24J005) — select the output voltage to match your LED strip or fixture system. Both models deliver 300W of stable constant voltage output.
-
Universal Commercial Input Voltage: Accepts 120–277VAC, 50–60Hz — compatible with standard US residential circuits and commercial 208V / 240V / 277V single-phase branch circuits, eliminating the need for voltage-specific inventory across different job sites.
-
Built-in Active PFC: Integrated active Power Factor Correction delivers PF ≥0.98 at 120V and ≥0.81 at 277V — meeting commercial energy codes, reducing reactive power demand on building electrical infrastructure, and qualifying for utility incentive programs.
-
High Efficiency — 85% at 220VAC: Operates at 85% power efficiency — minimizing heat generation and energy waste, which extends driver lifespan and reduces operating costs in continuous-duty commercial installations.
-
Flicker-Free Output: Designed for flicker-free performance — critical for office environments, retail displays, hospitality, and video/photography settings where light quality and occupant comfort are priorities.
-
Fine Output Voltage Tuning: Built-in output voltage fine-tune adjustment allows precise calibration to compensate for cable voltage drop in long LED strip runs — maintaining consistent brightness from start to end of the strip.
-
UL / cUL Listed — Type HL, Class 2: Certified UL/cUL Listed, Type HL for safe installation in commercial and residential environments — meeting NEC Class 2 requirements and simplifying wiring on the output side in most jurisdictions.
-
Dry, Damp & Wet Location Rated: Approved for installation in dry, damp, and wet locations — suitable for covered exterior applications, food service environments, natatoriums, and other moisture-exposed installations.
-
Comprehensive Protection Suite: Features short-circuit protection (Hiccup Mode, auto-recovery), over-voltage protection (auto-recovery at ≥28V for 24V model / ≥60V for 12V model), and over-temperature protection (auto-shutdown and recovery at 100°C ±10°C) — ensuring long-term reliability in high-demand operating conditions.
-
Full Protection Aluminum Housing: Housed in a rugged full aluminum enclosure for structural durability, EMI shielding, and efficient passive thermal management — rated for continuous operation from -40°C to +60°C ambient.
-
Junction Box Design — Flat or Vertical Mounting: Junction box form factor supports both flat and vertical mounting orientations — adapts cleanly to panel, plenum, or surface-mount installation scenarios.
The LMFV-300-J005 is a professional-grade 300W constant voltage LED driver engineered for commercial and architectural LED lighting installations requiring maximum dimming flexibility. With 5-in-1 dimming protocol support, universal 120–277V input, high active PFC, flicker-free output, and UL/cUL Class 2 certification — it delivers reliable, code-compliant performance in a compact aluminum junction box form factor. Available in 12V / 25A and 24V / 12.5A variants. Backed by a 5-year warranty.
