Green Watt Power’s 20-W GLCT series of constant-current dimmable LED power supplies offer a compact solution for Triac/ELV dimmer-compatible LED driver applications. Four models in the series offer output current ratings of 400, 500, 600, and 700 mA. Current range with dimming is 10% to 100% of the full rated output. Output voltage ranges from 14 to 28 V for all models. The IP65-rated supplies, with dimensions of 3.74 by 1.57 by 0.98 in. and weighing 0.157 kg, feature a universal ac input. Power factor correction measures 0.99, while total harmonic noise comes in at less than 20% Rise time is 150 ms. Operating temperature ranges from ‒25 to +60°C; storage temperature ranges from ‒40 to +85°C. Built-in protection includes overvoltage, short-circuit, overcurrent, and overtemperature.
