GSC18B 18W Single Output LED Power Supply F 110 M ■ Features Universal AC input / Full range (up to 277VAC) 2 pole AC inlet IEC320-C8 Built-in active PFC function Constant current design Protections: Short circuit Cooling by free air convection Fully isolated plastic case Class Ⅱ power unit, no FG No load power consumption<0.15W Low cost, high reliability 100% full load burn-in test 3 years warranty M SELV IP40 series 05 ■ Applications Indoor LED lighting Office lighting Commercial lighting Indoor LED decorative lighting ■ Description GSC18B series is a 18W external desktop LED power supply with PFC function. The design of this product is based on the “ plug and play ” concept for adaptors. The AC input side exploits the 2-Pin (Class Ⅱ, no FG) international standard inlet IEC320-C8, and the output side is equipped with the highly accepted DC connector (2.1x5.5x11mm) in the market. This product accepts 90~277VAC input and offers various constant current output models with 350mA/500mA/700mA/1050mA/1400mA. The design complies with the lighting requirements of EMI EN55015 and the harmonic current demand per EN61000-3-2 Class C. In addition, the no load power consumption is less than 0.15W, and the setup time is less than 500ms, making GSC18B conform to the ErP regulation required by European Union for lighting systems as well. ■ Model Encoding GSC 18 B - 350 Output current IEC320-C8 AC inlet Output wattage Series name File Name:GSC18B-SPEC 2015-09-03 GSC18B 18W Single Output LED Power Supply series SPECIFICATION MODEL RATED CURRENT GSC18B-350 GSC18B-500 GSC18B-700 GSC18B-1050 GSC18B-1400 350mA 500mA 700mA 1050mA 1400mA 18 ~ 36V 13 ~ 26V 8 ~ 17V 6 ~ 13V 18.2W OPERATING VOLTAGE RANGE Note.4 26 ~ 52V CURRENT ACCURACY Note.3 ±8.0% OUTPUT INPUT 18W 18.2W 17.9W RIPPLE & NOISE (max.)

All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature. 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor. 3. Please see "AC input voltage drop vs. output current characteristics" table. 4. Constant current operation region is within 50% ~100% rated output voltage. This is the suitable operation region for LED related applications, but please reconfirm special electrical requirements for some specific system design. 5. Direct connecting to LEDs is suggested, but is not suitable for using additional drivers.
