300W 12V Dimmable LED Power Supply, Triac and 0-10V, 100-130VAC Input, IP20

A 300W constant-voltage LED driver with a 12V DC output, intended for dimmable LED lighting installations in commercial and architectural interiors. It accepts 100-130VAC at 50-60Hz and supports both Triac and 0/1-10V dimming controls. The IP20, non-waterproof housing is built for dry indoor locations. Rated output current is 0-25A at 12V with a voltage tolerance of ±0.5V and ripple and noise of 250mVp-p. Typical full-load efficiency is 86%, with a power factor of 0.5 and maximum AC input current of 1.92A. Short circuit and overload protection operate in hiccup mode with automatic recovery, and over-temperature shutdown occurs at 100°C ±10°C. The aluminum alloy enclosure measures 288 x 50 x 30mm and weighs 0.5kg, with an operating range of -20°C to +50°C. The driver is ETL listed under UL file 5024093 and carries the CE mark.
