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 GSC25B conform to the ErP regulation required by European Union for lighting systems as well. ■ Model Encoding GSC 25 B - 350 Output current IEC320-C8 AC inlet Output wattage Series name File Name:GSC25B-SPEC 2015-04-16 GSC25B 25W Single Output LED Power Supply series SPECIFICATION MODEL RATED CURRENT GSC25B-350 GSC25B-500 GSC25B-700 GSC25B-1050 GSC25B-1400 350mA 500mA 700mA 1050mA 1400mA 26 ~ 52V 18 ~ 36V 12 ~ 24V 9 ~ 18V OPERATING VOLTAGE RANGE 36 ~ 72V CURRENT ACCURACY Note.3 ±8.0% OUTPUT INPUT 26W 25.2W 25.2W 25.2W 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.
